Specify colors of bars per column property

[philip-n]

I've hit this a couple of times in recent weeks and am not sure if I'm missing something, or if it is not possible, ... . Any hints are appreciated!

In our database, there's some model with a property that describes its category (e.g. column fruit with property type that could be apple, banana, ananas, ...).

I now want to show the current amounts of these categories - how many entries with category apple, banana, ... etc are there.

So what I do is

• Query builder
• Select the model under data
• Summarize by COUNT of property

This gives me a nice bar chart with one bar for apple, one for banana, ... . However, all bars are shown in the same color, and the options only allow to change that single color.

Is there any simple way to chose custom colors (so that the bar for apple could be colored red, banana yellow, ...)?

I've searched a bit on github and in the forum, but only found answers related to more complex things (stacked bar charts, time series with trends, ...).

Nope, we don’t support that yet

I had a similar requirement. You can fudge it by doing a second grouping on a field that results in a strict 1:1 mapping with the category you want to count/colour by (if you've got a unique "code" and "description" for your category that can work well). In my case I had to do join on the same table, so each row joined to itself, something like this:

Then set your chart to stack, and set the colours as needed:

This approach is very much a work around and will depend on the shape of your data, but it has come in handy for me a couple of times.
