Hi all! I’m trying to plot a heat map of one variable (with all values >>0), but on the same plot, I want to plot contours of two other variables where they equal 0. When I try countour! after plotting the heatmap, the colors of the heatmap go off, I guess because the other variables are 0. my at…

You could shift the additional datasets and their contour levels to the mean z0 of the primary dataset and request that the z0 contour be plotted for each shifted version: z0 = mean(mag) p = heatmap(P_range, δ_range, mag; xlabel="P", ylabel="δ", title="‖∇Q_T‖", color=:viridis, clims=cl) levels1 …

Is there a way to have heatmap and contours from other variables in Plots.jl with GR?

Perhaps a default white background of the contour plot covers everything below:

background_color = :transparent
