I’m currently converting some code from MATLAB to Julia, and have reached the stage where I have to do some graphics.

The picture shows the MATLAB plot on the right and my attempt in Julia using Makie.jl on the left. I’m almost there but I have some problems.

- I need to turn off the axes, grid and labels on the bottom two plots.
- The title refuses to appear on the top plot
- I need to add colorbars to the bottom two plots.
- Using ‘axis image’ in MATLAB the plot on the right has the coins that stay in proportion when the plot is resized. The Makie plot distorts the coins when I resize the window.

Any help gratefully received. My code is below. I’ve cut and pasted it as is, so there’s lots of crap in there, but I hope my feeble attempts at using Makie are clear. Be kind. This is my first attempt.

```
function solplot(sol::Solution)
x = vec(collect(range(0.0, sol.target.LX, length = sol.target.NX)))
y = vec(collect(range(0.0, sol.target.LY, length = sol.target.NY)))
Zrange = sol.Zmax - sol.Zmin
if Zrange == 0.0
title1 = @sprintf(
"RMS error = %2.2f%s.",
1000 * sol.err * sol.beamparams.beamdiameter,
"μ"
)
else
title1 = @sprintf(
"RMS error = %2.2f%sm (%2.1f%s).",
1000 * sol.err * sol.beamparams.beamdiameter,
"μ",
100 * sol.err * sol.beamparams.beamdiameter / Zrange,
"%"
)
end
scene1 = Makie.heatmap(
x,
y,

colormap = :bone,
