It’s safe to say that SAS Global Forum is a conference designed for users, by users. As your conference chair, I am excited by this year’s top-notch user sessions. More than 150 sessions are available, many by SAS users just like you. Wherever you work or whatever you do, you’ll find sessions relevant to your industry or job role. New to SAS? Been using SAS forever and want to learn something new? Managing SAS users? We have you covered. Search for sessions by industry or topic, then add those sessions to your agenda and personal calendar.

Creating a customizable agenda and experience

Besides two full days of amazing sessions, networking opportunities and more, many user sessions will be available on the SAS Users YouTube channel on May 20, 2021 at 10:00am ET. After you register, build your agenda and attend the sessions that most interest you when the conference begins. Once you’ve viewed a session, you can chat with the presenter. Don’t know where to start? Sample agendas are available in the Help Desk.

For the first time, proceedings will live on SAS Support Communities. Presenters have been busy adding their papers to the community. Everything is there, including full paper content, video presentations, and code on GitHub. It all premiers on “Day 3” of the conference, May 20. Have a question about the paper or code? You’ll be able to post a question on the community and ask the presenter.

Want training or help with your code?

Code Doctors are back this year. Check out the agenda for the specific times they’re available and make your appointment, so you’ll be sure to catch them and get their diagnosis of code errors. If you’re looking for training, you’ll be quite happy. Training is also back this year and it’s free! SAS instructor-led demos will be available on May 20, along with the user presentations on the SAS Users YouTube channel.

Chat with attendees and SAS

It is hard to replicate the buzz of a live conference, but we’ve tried our best to make you feel like you’re walking the conference floor. And we know networking is always an important component to any conference. We’ve made it possible for you to network with colleagues and SAS employees. Simply make your profile visible (by clicking on your photo) to connect with others, and you can schedule a meeting right from the attendee page. That’s almost easier than tracking down someone during the in-person event.

We know the exhibit hall is also a big draw for many attendees. This year’s Innovation Hub (formerly known as The Quad) has industry-focused booths and technology booths, where you can interact in real-time with SAS experts. There will also be a SAS Lounge where you can learn more about various SAS services and platforms such as SAS Support Communities and SAS Analytics Explorers.

Get started now

I’ve highlighted a lot in this blog post, but I encourage you to view this 7-minute Innovation Hub video. It goes in depth on the Hub and all its features.

This year there is no reason not to register for SAS Global Forum…and attend as few or as many sessions as you want. Why? Because the conference is FREE!

Where else can you get such quality SAS content and learning opportunities? Nowhere, which is why I encourage you to register today. See you soon!

Ever heard of Mandelbrot set? I learned about it recently from an article introducing a book translated from the ‘Le Grand Roman des Maths’ by Mickaël Launay. I was impressed and thought I would see if I could draw one in SAS Visual Analytics.

Here are the seven steps I took:

1. Generate the data set

The first problem is where to get the data set. SAS documentation provides  this sample using DS2 and HPDS2 to generate the data set. I changed the code to make it run with SAS data step. When I run my code in SAS Studio, and the PROC GCONTOUR renders the graph shown below.

2. Assign data to numeric series plot

Now I get the generated Mandelbrot data set, which has about 360K rows and three numeric columns: p, q and mesh. Now it’s ready to upload the Mandelbrot dataset in SAS Visual Analytics – and I’m ready to start my drawing 😊.

I am going to use a numeric series plot to draw the graph. Realizing that the system data limitation for numeric series plot is 3,000, I need to override it by checking the ‘Options’ -> ‘Object’ -> ‘Override system data limit’. I reset it to 500,000 based on my VA server capacity. (This value should be adjusted based on your VA environment capability.)

Now assign the p to ‘X axis’, the q to ‘Y axis’, the mesh to ‘Group’ (be sure to change the classification of mesh to ‘Category’), and happily wait for the rendering of the graph.

Unfortunately, I got the message: ‘No data appears because too many values were returned from the query. Filter your data to reduce the number of values.’

3. Filter the data

So I must compromise to break the data into several parts with filters, and then use Precision layout to put them together.

I am using the q value to create the filter. Try a couple of times and something like “( 'q'n BetweenInclusive(-1.5, -0.9) ) OR ( 'q'n Missing )” works for me. Thus, I decide to break the whole data set into five parts for the span of the q (from -1.5 to 1.5) and draw each part in one numeric series plot.

 4. Use Precision layout

To put together all the parts with the filtered data in each numeric series plot, I need to have the Precision Container to hold all five plots. To put them together nicely, I need to adjust the options for the numeric series plots.

An easy way is to set for one and duplicate for others. Here are option settings I am using:

  • In ‘Object’ -> ‘Title’, set to ‘No title’;
  • Check the ‘Style’ -> ‘Padding’, and set the value to 0;
  • Uncheck the ‘Graph Frame’ -> ‘Grid lines’;
  • In ‘Series’ -> ‘Line thickness’: set to 1;
  • In ‘Series’ -> ‘Markers’ -> ‘Marker size’: set to 3;
  • Uncheck ‘X Axis Options -> ‘Axis label’, and uncheck ‘Tick values’;
  • Uncheck ‘Y Axis Options -> ‘Axis label’, and uncheck ‘Tick values’;
  • In ‘Legend’ -> ‘Visibility’, choose ‘Off’.

5. Duplicate and set layout for the five numeric series plots

Now, I have one numeric series plot that has options set up as described, and one filter on the q.

Next is to duplicate the numeric series plot four times and change the filter for each. What I want, is to have the five numeric series plots add up to the whole span of the q (from 1.5 to -1.5), from up to bottom.

For each of the numeric series plot, set the value in its ‘Options’ -> ‘Layout’ section as following. The Filter column is indicating the filter range of the q.

Filter for q Left Top Width Height
0.9 ~ 1.5 0% 0% 100% 20%
0.3 ~ 0.9 0% 18% 100% 20%
-0.3 ~ 0.3 0% 36% 100% 20%
-0.9 ~ -0.3 0% 54% 100% 20%
-1.5 ~ -0.9 0% 72% 100% 20%

 

6. Set Display Rules

With above steps, now the graph is rendered using the default colors in VA.

But I like the colors used by the codes, I want to change them using display rule. In the Display Rules tab, create a display rule with the mesh. And add each mesh value with the wanted color.

For example, if the mesh value is 3, look up the GOPTIONS segment in the codes and note that it uses the ‘CX003366’ color value. In SAS Visual Analytics, go to the Custom color tab of creating display rule. For the mesh value 3, enter ‘003366’ in the ‘Hex value’ box.

Of course, I need some patience to get all the mesh values colored with display rules.

7. Render the Mandelbrot set

And now, I have drawn the Mandelbrot set in SAS Visual Analytics. I also put a Text Object (‘Mandelbrot set’) below the graph to show what is graphing.

How do you like it? Just give it a try and have fun!

Readers of my earlier post Discover Visual Analytics Report Paths with REST APIs asked for ways to export SAS Visual Analytics (VA) report content programmatically. I know this is a topic of interest from many VA report designers. So, I think it’s better to write something on this and I hope this post can be of help for such requirements.

We all know SAS Visual Analytics provides ability to export reports to PDF in the product GUI. In addition, the REST API for visualization also provides APIs to save the entire report or report objects to SVG image. In this article, I will use the SAS VA SDK to export VA reports to a PDF file. Note: this task requires some basic knowledge with JavaScript programming; good thing is, it’s not that complicated.

The SAS VA SDK provides a set of components and APIs that enable you to render anything from the entire report down to individual report parts. I am going to show how to export VA report content to a PDF document.

The VA SDK requires several prerequisites be set up in SAS Viya. These steps are covered in the documentation and I’ll not detail them here. For reference, these may include enabling CORS, CSRF, HTTPS and Cross-site cookies. Also, the VA SDK provides options to connect to SAS Viya using 'credentials' or 'guest' authentication. If you want to have the report accessible by the 'guest' user, it needs the

<script async src="https://unpkg.com/@sassoftware/va-report-components@latest/dist/umd/va-report-components.js"></script>

*Note: I am using va-report-components@latest above to invoke the latest available version of SDK library. You may also indicate a specific version, such as @0.14.0 for version 0.14.0 of the SDK library.

Get the VA report URI

If you are not familiar with how to get the reportUri, refer to the 'Get the ReportURI' section in the Using REST API to transform a Visual Analytics Report post. In this example I received the following response to my API call: reportUri=/reports/reports/cbf97b0a-457d-4b4f-8913-547e0cdf390c.

Display the VA report in the web page

This can be done by embedding an HTML custom tag in the section of your web page. The VA SDK supports three types of HTML custom tags: the entire report, a report page, or individual report objects. Each type is introduced below.

  1. <sas-report>
  2. In the sample code below, the URL represents the SAS Viya server, the authenticationType is 'guest' or 'credentials', and the reportUri identifies the report to render.

            <sas-report
                authenticationType="guest"
                url="http://sas-viya-server.com"
                reportUri="/reports/reports/c3c6befb-3981-4c9e-b011-7dc11dec5e37">
            </sas-report>
  3. <sas-report-page>
  4. In the sample code below, the URL represents the SAS Viya server, the authenticationType is ‘guest’ or ‘credentials’, the reportUri identifies the report, and the pageName indicates which page within the report to render. You can use and actual page number or use pageIndex="0" which refers to the first page in the report. You can get the tag in SAS Visual Analytics, by clicking the 'Copy link…' menu item from the context menu of the page, choosing the 'Embeddable web component' option and clicking the 'Copy Link' button.

            <sas-report-page
                authenticationType="credentials"
                url="http://sas-viya-server.com"
                reportUri="/reports/reports/c3c6befb-3981-4c9e-b011-7dc11dec5e37"
                pageName="vi20">
          </sas-report-page>
  5. <sas-report-object>
  6. In the sample code below, the URL represents the SAS Viya server, the authenticationType is 'guest' or 'credentials', the reportUri identifies the report, and the objectName gives the name of the object in VA report to render. You can get the tag in SAS Visual Analytics, by clicking the 'Copy link…' menu item from the context menu of any an object, choosing the 'Embeddable web component' option and clicking the 'Copy Link' button.

            <sas-report-object
                authenticationType="guest"
                url="http://sas-viya-server.com"
                reportUri="/reports/reports/c3c6befb-3981-4c9e-b011-7dc11dec5e37"
                objectName="ve27">
            </sas-report-object>

Make a function to export PDF

Remember when I said you’d need a little JavaScript knowledge? Well, the time is now. Follow the steps below to create a function in JavaScript which exports the report, page or object to a PDF file.

  1. Load the global vaReportComponents from SDK library. This is done by the window.addEventListener('vaReportComponents.loaded', function()) function.
  2. Next, get the report handle by calling the getReportHandle method on an object given by one type of three custom HTML tags. Something like myReport.getReportHandle(), myReportPage.getReportHandle(), or myReportObject.getReportHandle().
  3. Invoke the reportHandle.exportPDF(options) function to export the PDF. The options give the customized properties of the exported report. If no option is specified, the default value for the options is used. For example, the options can have the 'includeCoverPage: false' which means the exported PDF will not generate the cover page for the report. There are multiple options for the exportPDF function, please refer the VA SDK document for more info and its usage.

Put all together

Below are the snippets to generate the PDF document for a report page, using the options of no cover page and no appendix.

  1. I put a button in the HTML page, so I can click the button to trigger the export PDF function.
  2. The page displays the report page I am going to export. I’ve added id="sasReportPage" in the sas-report-page html tag, so I can get the DOM element by its ID quickly using the document.getElementById("sasReportPage") method.
  3. <html>
    <head> <meta http-equiv="content-Type" content="text/html"> 
    <script async src="https://unpkg.com/@sassoftware/va-report-components@latest/dist/umd/va-report-components.js"></script>
    </head>
     
    <body>
    <div id="buttons"> Export the PDF document of the VA report page by clicking the 
    <button type="button" class="btn_load" id ="PrintBtn" onclick="PrintPDF()"> EXPORT PDF </button> button. </div>
    <div >
            <sas-report-page id="sasReportPage"
                authenticationType="credentials" 
                url="https://sas-viya.com" 
                reportUri="/reports/reports/cbf97b0a-457d-4b4f-8913-547e0cdf390c" pageIndex=0>
        </sas-report-pag>
    </div>
    <script>
        function PrintPDF() {
    		// load the global variable of vaReportComponents
                document.addEventListener('vaReportComponents.loaded', function(){});
                const myReport = document.getElementById("sasReportPage");
    		// get the report page handle
            myReport.getReportHandle().then((reportHandle) => {
    	  	    // set options – not include cover page and appendix of the report
    const options = {
                          includeCoverPage: false,
                          includeAppendix: false,
                   includedReportObjects: ["vi6"],
                };
     
    	   	    // call the exportPDF function to export PDF document
                reportHandle.exportPDF(options).then((pdfUrl) => {
                          // Open the exported PDF in a new window
                      window.open(pdfUrl, '_blank');
            });
            });
    }
    </script>
    </body>
    </html>
  4. Save the code above as an html page, so I can access it from a web server. For example, save to my localhost/myproj/mysdk.html. When I load the page successfully, it shows the VA report page embedded in my html page as below:
  5. VA report page embedded in my html page

  6. Now, clicking the 'EXPORT PDF' button, opens a new page with exported PDF document like below:
  7. Exported PDF document

Summary

In this post, we’ve learned how to use the SAS VA SDK to call reports, display them in a web page and export them to a PDF file. In the sample snippets, I used the sas-report-page html tag to export one page of a VA report. Change the html tag to sas-report accordingly, and you can easily export the whole VA report, or change it to sas-report-object to export an object in the VA report.

In one of my prior posts, I discussed the power behind a Hidden Data Role in SAS Visual Analytics. In this post, I provide a summary of places you can go to learn more about other enhancements to the List Table.

The List Table can be more than just a black-and-white ledger style visual. Here is one example where I’ve highlighted some of the enhancements you can apply to the List Table:

List Table Example 1

You can also control the styling of the List Table by changing the header and total cell background colors as well as an alternating row color:

If you want to style your List Table for all users to have the same color scheme and other style enhancements, consider using either a Report Theme or Object Templates for consistency across report developers.
