Customising each bar drawn within a chart

[markedup]

What is the problem?

I'd like to visually round off the ends of a StackedBarChart element’s bars – both foreground data and background guides – like so: I'd also like to apply a gradient effect to each bar, as per the illustration above.

However, having read through the documentation and looked at the examples, I haven't discovered if customisation for individual bar chart elements is possible in this specific way.

Can someone tell me how to apply these customisations to each bar please?

I don't think we support rounded corners on bar-charts at the moment. We draw the bars as "shapes" instead of rectangles and as such the don't support any radius props.

The gradients is supported, have a look at this example

Thanks @JesperLekland, appreciate the details regarding per-bar drawing options (specifically rounding).

Regarding the gradients, do you have an example of the gradient being applied relative to the bar's size within the overall graph "spectrum"? Or will I need to create a proportional gradient start and finish per bar, based on the overall chart gradient?

[JesperLekland]

@markedup Unfortunately don't have an example. I think you'll need to create one gradient per bar and do some calculations based on it's relation to the entire data set min/max. Perhaps some color interpolation

No worries, @JesperLekland – thanks again for your help. I was thinking it would need to be an interpolated, per-bar gradient; if I produce anything useful, I'll share it here.

Great, thanks for the input. I'll keep this issue open to remind me about the borderRadius for BarChart

HI @markedup , were you able to solve this? I'm trying to do something similar, but I don't know how to make the color fill only a certain height of the bar

@JesperLekland Please I'd appreciate your thoughts on this too

@markedup Hi, pls help i dont know how to border this bar.
