In this module you will learn how to use the Table Heatmap Power BI Custom Visual. The Table Heatmap has the look and feel of a pivot table or matrix report. However, instead of seeing traditional values in the table you actually see colors that represent your values instead.
Module 15 – Table Heatmap
- Power BI Custom Visual – Table Heatmap
- Dataset – Monthly Sales.xlsx
- Completed Example – Module 15 – Table Heatmap.pbix
- In the Table Heatmap the color of the boxes is determined by the value in your measure.
- Only 1 category field can be used, which will dynamically generate the number of columns based on the number of distinct values your field has.
- The number and types of colors can be changed using some of the settings we’ll discuss below.
This shows a Table Heatmap with Month as the category column and individual fields 2013, 2014, 2015, 2016 in the Y axis.
- Under the Format paintbrush there isn’t much available to customize the appearance of the Table Heatmap.
- The one section specific to the Table Heatmap that you have available is found under the General section.
- By changing the Colorbrewer property you are able to swap out the color palette being used
- You can also use the Buckets setting to increase/decrease the number of colors that are used in the color palette you’ve selected.
- There are many color palettes that you can use in the Colorbrewer property but unfortunately they’re not well documented. Here’s a list of values that you could use in this property:
- Purples, Blues, Greens, Oranges, Reds, Greys,
- Spectral, RdYlGn,
- Paired, Pastel1, Set1, Set2, Set
- Experiment with these and see which makes most sense for your solution
- In addition to these properties you have a set of settings that appears on every visual to adjust the background color, add a border around the visual and lock the aspect ratio.
