Fat band using matplotlib in python
matplotlib, numpy, physics, python, thickness
Solution
You can do this using `fill_between`.
For example, to have half the `bandwidth` above and half below (and also drawing the original line using `plot`):
import matplotlib.pyplot as P
import numpy as N
x_value = N.arange(0,10,1)
y_value = N.random.rand(10)
bandwidth = N.random.rand(10)*10
print bandwidth
P.fill_between(x_value, y_value+bandwidth/2, y_value-bandwidth/2, alpha=.5)
P.plot(x_value,y_value)
P.show()
Problem
I would like to plot a line with varying thickness using matplotlib in python. To be clearer, I have the following variable ``` import matplotlib.pyplot as P import numpy as N x_value = N.arange(0,10,1) y_value = N.random.rand(10) bandwidth = N.random.rand(10)*10 P.plot(x_value,y_value,bandwidth) ``` I would like to plot a line with x_value and y_value and a thickness that vary with the x_value position and given by the bandwidth vector. A possible solution that I see would be to draw the upper and lower line (i.e. I take y_value[index] +- bandwidth[index]/2 and plot those two lines. Then I could try to fill the space between the two lines (how?) If you have any suggestions? Thank you, Samuel.
