Coloring by bars and not by stacks in a StackBar chart

[A1exandre]

Hi all, and thanks @danielgindi & @PhilJay for this great piece of work :)

I have a chart with stack bars and I'm trying to have each bar with a different color.

However, when we have stack bars the barChartDataSet.colors property does not set the colors for the bars anymore but for the stacks.

Is there anyway to set the colors independently for each bar?
Thanks!

dataSet.setColors(...)

dataSet.colors = ...

Just like you normally set colors. In stacked-bars, colors are reused for bars.

Sorry I wasn't very clear.
I use dataSet.colors = ...

However, it seems that the coloring automatically switch from coloring-by-bar to coloring-by-stack when we use stacks.

Because of this, i get that

And what I want is this

(My stacks are not supposed to have different colors, they should just be seen because of the borders)

I found a temporary fix by modifying the drawDataSet function of BarChartRenderer.swift.
Line 237 was CGContextSetFillColorWithColor(context, dataSet.colorAt(k).CGColor) and I replaced it with
CGContextSetFillColorWithColor(context, dataSet.colorAt(j).CGColor)

However, having a dataSet.colorByBar or dataSet.colorByStack property to do this would be nice.

your cae is different, stack bar chart will repeat the value, but you don't want it. Then you have to customized it your self.
BTW, to me, it does not make sense(?) that a stacked bar chart should have the same color, unless you have other ways to distinguish them. However, from your screenshot, it looks just like a normal bar chart. Why using stack not normal for this case?
