Hi,

I am trying to plot a heatmap in a polar plot like so:

```julia
contourf(deg2rad.(collect((0:360))),deg2rad.(collect(0:1:85)), B, aspect_ratio=:equal, proj=:polar, color=:viridis, alpha=0.5)

```

But I get a tiny little figure

Why is that? And how can I fix it? Thank you!

Hi RBraghiere,

Did you make any progress with this? I have the same issue.  
e.g.

```julia
using Plots
pyplot()
using PyPlot

X = range(1,stop=100,length=100)
Y = range(1,stop=100,length=100)
Z = rand(100,100)

h1 = heatmap(
     X,Y, Z,
     proj=:polar
    )

```

Does anyone have any ideas?

Just bumping this up in case anyone else is having the same issue or has any ideas? I still haven’t found a solution ☹

This should be fixed in Plots \>= v1.7.2 ([https://github.com/JuliaPlots/Plots.jl/pull/3088](https://github.com/JuliaPlots/Plots.jl/pull/3088)).
