In material science, we frequently have to plot pole figures to know the symmetry of the as-grown thin film. The Pole figure is a polar contour plot. I struggle to plot it in Julia. It would be a great help if someone helped me out. The pole figure should look like: But what I am getting is like …

[image] How to plot heatmap and contour plots in polar coordinates with Plots.jl? Visualization It is really nice to have polar coordinates implemented in Plots.jl: using Plots; gr() plot(linspace(0,3π,100), rand(100), proj=:polar, m=:red) [polar] and even nicer to int…

Its not working, I am getting following error: MethodError: no method matching heatmap_edges(::Vector{Float64}, ::Symbol, ::Vector{Float64}, ::Symbol, ::Tuple{Int64}) Closest candidates are: heatmap_edges(::AbstractVector, ::Symbol, ::AbstractVector, ::Symbol, ::Tuple{Int64, Int64}) at C:\Users\u…

Please share the exact code you tried to run and quote it in backquotes so that Discourse highlights it correctly.

I am using the following code (Julia 1.7.0). using DataFrames, Plots, DelimitedFiles, Glob, LaTeXStrings f=Glob.glob("*.txt") df=readdlm(f[1],comment_char='#',comments=true) df=DataFrame(df,:auto) Chi,phi,I=df[:,1],df[:,2],df[:,3] pyplot() c=heatmap(Chi,phi,I,fill=true,c=:Spectral,frame=:box,p…

Ideally you don’t need to share a file, just create fake data and make a minimum working example. That way we can easily help without downloading data.

Plots.jl pyplot() backend works ( see example here ) but with some limitations and PyPlot.jl seems to work best ( see github post here ). PyPlot example below: using PyPlot fig = plt.figure() ax = fig.add_subplot(111, projection="polar") ρ = LinRange(0., 7, 200) θ = LinRange(0., 2π, 360) funp(ρ,θ) = …

Thanks, Jheinen. This solution also works, but how could one change other plot properties like color and levels

@jheinen , what do the labels 100.5 and 0.5 mean?

I think that’s fixed in the meantime:

using GR
ρ = LinRange(0., 7, 200)
θ = LinRange(0., 2π, 360)
funp(ρ,θ) =  sin(2ρ) * cos(θ)
polarheatmap(ρ,θ,funp.(ρ,θ')')
