Hello, I am trying to display a bar chart of a measure on certain countries.
For clarity, I want to use the flags of the countries rather than the names in the legend of the bar chart.
I am aware of this post : https://www.googlecloudcommunity.com/gc/Technical-Tips-Tricks/How-to-Add-Images-to-Visualizations/ta... which illustrates what i want to do. For this I use base64 images in the html field of my dimension, which display properly in a table visualisation. However, while url-based images display fine when in bar chart, the base64 images do not display.
What can I do to make this work without using url-based images?
