设置颜色条 matplotlib 的标签

Question

I have spent a couple hours trying to figure this out. I want the colorbar to display three values along the bar, [0, 3315/2, 3315]. However, I am just getting this result:

Code:

print(max(average_powers)) # 3314.455810547
sm = plt.cm.ScalarMappable(cmap=cmap)
sm.set_array([])
mn=int(np.floor(0)) 3 
mx=int(np.ceil(max(average_powers)))
md=(mx-mn)/2
cb = plt.colorbar(sm)
cb.set_ticks([mn,md,mx])
cb.set_ticklabels([mn,md,mx],update_ticks=True)
cb.set_label('Magnitude of Average Power for turbine')

Thanks in advance!

Answer 1

Replace

cb.set_ticks([mn,md,mx])

With

cb.set_ticks([0, 0.5, 1])
