I do have a problem to set the color I want for my dimension in a Mekko Chart.
Let's resume my situation :
For each category, i have three additionals datas : "Red color", "Green color" and "Blue color".
In every other charts, I'm using the background color of the first expression with the RGB() function to set the color of my category dimension. However, I can't find this option in the Mekko chart.
Did anyone already face this problem ?
