Hi! I would like to plot only the very contents of a plot (a heatmap in this case) using Plots.jl.
I’ve set the aspect ratio to 1:1, hidden the axes, hidden the color bar, set the margins to zero, and set the image size to match the size of the actual heatmap. However, I still get a white border around the plot, and the size of the plot is not exactly what I set it to be.
Here is a sample code:
using Plots using Plots.PlotMeasures const N = 400 const xs = 1:N const ys = 1:N const values = rand(N, N) heatmap( xs, ys, values, aspect_ratio=:equal, # 1:1 aspect ratio axis=(, false), # Hide axes cbar=false, # Hide color bar margins=0px, # Hide margins size=(N, N), # Figure size ) savefig("plot.png")
Notice the white border around the plot and the
399 × 400 dimensions instead of
400 × 400.
