How can I set maximum and minimum value in the color scale of contourf of matplotlib?
I explain. I have a set of data and I want to put as maximum in the color scale the 95% percentile of the data.
I have tried in this way:
goh = colors.Normalize(0, perchi)
plt.contourf(x, y, B, norm = goh) #cmap = plt.cm.hot,
plt.colorbar()
plt.show()
but it returns to me a plot with only one color...and also the scale is monochromatic... I want the whole color scale linear but in the range (min, perchi) and not in (min, max). I want that the points between perchi and max are shown as if the y have perchi values...
How could I do?
to set the maximum and minimum valued you can do something like:
import matplotlib.pylab as plt
import numpy as np
# Create fake data
B = np.random.uniform(0, 10, size=(100, 100))
plt.contourf(B, vmin=2, vmax=8)
plt.colorbar()
The values outside the range are set to the maximum and minimum.
