I’ll copy this text block here and paste it into the editor. The next thing to do is to set the labels to horizontal and turn off the X axis. We’ll change this from a bar chart to a column chart by flipping the X and Y. Once we have those locked in, we can use a simple bar chart specification, select Toxin for the category, and select Size for the measure.Īnd there we go. We’ll add in our Size measure, which is a simple equal to one. We’ll add a slicer using our Deneb visual, and add in our Toxins as a value. Vega-Lite doesn’t have a specific graphic for a slicer, but you can use visuals instead of slicers.įor the slicers, let’s try to use bar charts of a fixed size. Then we’ll go back to the report and adjust the size a little bit. We’ll also change the alignment from left to right and change the X coordinate to 380. Let’s change the font size to 12, and the font style to italic. We don’t need a layer and a second mark so let’s get rid of those, and then change the name of the measure to report info.

We can put that JSON code in this new visual and use the empty specification again.įor this visual, we only have one mark to use. Let’s go back to the visual we just developed to copy the JSON code. We’ll add a new Deneb visual and place it on the top right corner and add our report info measure. Let’s move on to the report info text box. Then we’ll go back and resize the visual just a little bit. Let’s now change the circle mark into a text mark using our page subtitle, and then make the changes as needed. Let’s add a few characteristics for the visual to mark. The next thing we’ll do is to copy some of the font attributes into the visual here. We’ll grab a block from my snippets file and set the alignment in the editor to the left, then align the center mark to 0. The next step is to change the alignment of the text. Now we can see that the text is coming in the top left. Let’s make a layered visual with the text box and a circle mark.Īnd we can now see a circle is located at the center of the entire visual.Īnother thing we can do is change the position of the origin of the visual by setting the X and Y coordinates. Let’s visualize it by adding a circle mark to show us where the origin is. Then we’ll look at the position to see if it is centered in the visual. We can use Control and the mouse wheel to make it bigger. Then we go over to our snippets file and use the page title measure for our visual. The first thing to do is to add a measure with our values (page title and page subtitle), then choose an empty specification. Since Vega-Lite is a graphical language for visuals, there isn’t an obvious method to create a text box.īut since Vega-Lite visual is just a collection of marks, I thought I might be able to use only text marks to simulate a text box. I created a number of blank pages on to the title text box. So there were no remaining visuals only the data, the data model, and the DAX calculations remained. To start, I took a copy of my Challenge #17 submission and deleted all the pages. Before we begin, just a quick note on the development environment. Now let’s take a look at each visual intern as we develop them from scratch.
We have a slicer for Years, a slicer for States, a slicer for Toxins, a metrics card, and a main visual displaying the Toxin Concentration that can be sorted by State and Year. There are 7 different visuals and 2 text boxes at the top. An Overview Of The Report Page In Vega-Lite I didn’t spend much time at all with the data either, so I won’t spend any time on the development of the dataset other than to include the air toxins portion in my report. My goal for this challenge was to gain experience using the Deneb custom visual, which is why I chose to use it solely, and not to use any standard Power BI visuals. This received some positive feedback, which is why I decided to make a tutorial on how I used Vega-Lite in my submission.

I used it exclusively in my partial submission for the Enterprise DNA Challenge #17 on environmental data reporting. In today’s blog post, I’ll talk about the newly available Deneb Vega-Lite custom visual for Power BI.
