Multiple figures side by side with rasters tcoloborx

Question

Context

Based on this answer, I can have 2 figures side by side with adjusted width, same height for sub-figures.

The same approach works for multiple graphs to get something like

I created \newcommand to include 2, 3, 4 graphs side by side. However, I could certainly benefit from automation of this task with keys.

My question

How can I adjust the \width of each raster (same height) so they can fit harmoniously on the \textwidth ?

How can I use tcolorbox raster for this task ?

So far, here is where I stand

Next steps

In a future question, I'll ask how to enter a list of figures with their captions to avoid hardcoding. But one step at a time :)

Edit 1

Using raster equal height as described in the anwer leads to

that is not what I am trying to reach.

@DG' thank you but. using
%raster width = \fullPage, %raster width = \textwidth, raster columns = #1, %raster force size = false, %raster equal height=rows, raster equal height, size = fbox, colframe = blue!50, colback = white, fonttitle = \bfseries, center title, drop fuzzy shadow, ]``` leads to the output in Edit 1 — JeT, Mar 01 '22 at 09:27
tcbraster divides linewidth in several equal width columns. If you want/need different width columns, you have to adjust them by hand. — Ignasi, Mar 01 '22 at 19:40
@Ignasi Thank you for your extremely useful comment. As we say in French "it puts the church in the middle of the village" :) — JeT, Mar 01 '22 at 20:14

Using raster equal height I get this output:

Sorry, I don't get it. The raster is fixed and the boxes are the same height. What do you want to change? — DG', Mar 01 '22 at 09:38
Same height yes, but the width is adjusted as you can see on the 3 graphs below "The same approach works for multiple graphs to get something like" in my question. I'd like to know if I can mimic that with rasters. — JeT, Mar 01 '22 at 09:40
I do actually. I updated the second image on my question to reflect that. — JeT, Mar 01 '22 at 09:56
As far as I can see, you have to stick to columns. Maybe someone else finds a solution that allows flexible widths — DG', Mar 01 '22 at 10:08
