Matplotlib multiple set_over / under - G_rizzle - Feb-14-2022
Hey,
I'm plotting gradients of a surface. Most of them lay between 0 -1, but there are also a few from 1 - 700.
Right now im coloring gradients > 1 in matplotlib via the set_over function
label_schriftgroesse = 20
schriftart = "Courier"
fig, ax = plt.subplots(figsize=(30,15))
custom_cmap = copy.copy(cm.get_cmap("gray"))
custom_cmap.set_over(color=[1,1,0])
plt.imshow(G_np, cmap = custom_cmap,
origin="lower",
vmax = 1,
extent=[x_koordinaten_np[0],x_koordinaten_np[-1], # X-Werte
y_koordinaten_np[0],y_koordinaten_np[-1]], # y-Werte
interpolation='none')
ax.set_xlabel('x [mm]', fontsize=label_schriftgroesse, fontname = schriftart)
ax.set_ylabel('y [mm]', fontsize=label_schriftgroesse, fontname = schriftart)
clb = plt.colorbar(extend = 'max')
clb.set_label("z [mm]", fontsize=label_schriftgroesse, fontname = schriftart)
plt.show()giving me the attached picture below.actually it would be great not just to plot everything >1 in one colour, but plotting for example values between 1-100 green, 100-200 blue etc etc.
How can i achieve that?
