Dear All, I want to use the following plot function from Matlab in Julia. I could not find the correct commands of Julia to do this work. subplot(1,1,1) pcolor(con), shading interp, ... axis('off'), axis('equal'), title('simulation'); colorbar temp=['fig',num2str(jj),'.png']; saveas…

Use can try the Plots.jl package. This can be installed by typing ] add Plots in the REPL. using Plots d = rand(5, 5) p = heatmap(d, aspect_ratio=:equal, axis=false, title="simulation") # or p = contour(d, aspect_ratio=:equal, axis=false, title="simulation") savefig(p, "myplot.png")

Julia doesn’t have builtin plotting so you would need to use a plotting library (package). What have you tried so far?

Hi Kristoffer, thank your for reply! I am trying to plot the phase-field value in 2D using FDM, example con := zeros(Float64,32,32) In Matlab : pcolor(con), shading interp this simple command works well.

Yeah, but what have you tried in Julia? What plotting packages have you used and what examples of these have you tried to modify to get something that looks like the Matlab plot?

[image] Aquaman: pcolor using PyPlot M = rand(10, 10) pcolormesh(M) There are some Issues with PyPlot in MKL Julia, hence, How can I use Plots.jl ?

Have a look at the Plots.jl examples here: http://docs.juliaplots.org/latest/examples/gr/ and see whether there’s a plot that looks like the one you’re after. You can use Plots like any other package by doing using Plots, by default it will use the GR backend.

Hi @feanor12 @nilshg @kristoffer.carlsson , many thanks for your support!

[image] Aquaman: temp=[‘fig’,num2str(jj),‘.png’]; saveas(gca,temp); how can define the name of file automatically in Julia, i.e. temp=['fig',num2str(jj),'.png']; saveas(gca,temp); fig1.png fig2.png … fig30.png …

savefig(p, "fig"*string(jj)*".png")

String interpolation is really useful for that: savefig(p, "fig$(jj).png")

[image] Diego_Javier_Zea: savefig(p, “fig$(jj).png”) very nice, thank you!
