Hi, I want to plot two region_plots into one plot. The idea is if you use different colors for the inequalities you can see how the regions change. A minimal example:
var('x,y')
plot1=region_plot(x<y,(x,0,1),(y,0,1),incol='red')
plot2=region_plot(2*x<y,(x,0,1),(y,0,1),incol='blue')
show(plot2+plot1)
I do not know how to manage this, since zorder or opacity are not working for region_plot. Does anybody know how to make this work (by the way I use sagenb.org)? Thanks in advance
