How to display image on Heat Map visualization

#1

We ran across a blog on Dundas website that talks about Heat Map with an example of sales people images display along side the heat map (see screenshot below). The blog didn’t go into detail on how to get the image to display.

Here’s the link to the blog: https://www.dundas.com/resources/blogs/from-heat-map-charts-to-color-scale-legends-experience-dundas-bi-version-7

We were able to reproduce a similar heat map chart using the Heat Map visualization. However, we couldn’t figure out how to get the images to show along side the names and the heat map. We have a field that stores the URLs pointing to the images. I tried adding the URL field to the metric set that the heat map visualization uses. That didn’t work. I assume that we would need to use the Data Image visualization to get the image to show. If that’s the case, how do you link the Data Image visualization to the Heat Map so that when the Heat Map shows 10 rows of data, the Data Image will show 10 images as well.

Hi Nathan,

As it stands today, the chart doesn’t have a concept of adding images to the axis scale.

In the case of this visualization, a table with the images was positioned and aligned beside the heat map. It was known the numbers of rows would be fixed, meaning that from day-to-day we don’t get to get much fluctuation in the data. So this side-by-side trick was ok.

If you’re in a situation where the number of rows could change, you should use a scorecard to create something like this. Build a single row using a Data Label, Data Image, and a Single Row Heatmap and allow the Scorecard to repeat based on your data.

Thanks! Since the numbers of rows will fluctuate based on the filter values, I will give the scorecard option a try.
