Drawing stripped and dodged barplot

[harrysw1729]

This is just a repeat of my unanswered question at Discourse. :(

In short, I tried to create a dodged barplot where the dodged bar would have different hatch patterns. Below is a short example of my attempt:

using CairoMakie

cats = repeat(Float64[1, 2], inner=2)
heights = repeat(Float64[1, 2], outer=2)
group = repeat([1, 2], outer=2)

directions = [[1.0, 1.0], [-1.0, 1.0]]
patterns = Any[Makie.LinePattern(background_color=(:red, 0.5), direction=direction) for direction in directions]

fig = Figure()
barplot(fig[1, 1], cats, heights, dodge=group, color=patterns[group])
fig

The code was based on the documentation about dodged bars and stripped bars. However, the code ran into the following error:

ERROR: StackOverflowError:
Stacktrace:
 [1] float32type(::Type{DataType}) (repeats 2 times)
   @ Makie ~/.julia/packages/Makie/eziUH/src/conversions.jl:706

The individual line patterns defined in my codes seemed to be fine in that the code would run without any issue I fix the line pattern, such as the one below.

fig2 = Figure()
barplot(fig2[1, 1], cats, heights, dodge=group, color=patterns[1])
fig2

Below is the version information:

Could you post the full error, including the stacktrace, along with which versions of Makie and Julia you're running?

You can get the versions by:

versioninfo()

and

using Pkg
Pkg.status(["CairoMakie", "Makie"])

I just edited the post to include the information. Thanks a lot!

I also realized that my CairoMakie was one version behind. Strangely, after I updated it, the error message changed. 😅

I think you're running into two issues:

1. Patterns are currently one-per-plot
2. The Any[] might result in Makie going down the wrong conversion path as that's type based.

Thanks for the reply. I tried removing Any but the StackTrace and the error message remained the same.

As for your point 1, could you please elaborate on that? Any suggestions on fixing the issue?
