Hello everyone,
I would like to draw the attention on the slow startup of matplotlib.
Indeed, running matplotlib takes a long time.
I performed the following sequence :
```bash
#!/bin/bash
for i in * ; do python2 -c "from temp import * ; plot_(\"${i}\") " ; done
```
with temp.py like this :
```python
#!/usr/bin/env python2
import sys
import matplotlib.pyplot as plt
import read_data as rd
import numpy
def plot_( fname ):
P,I = rd.read_data(fname)
Iprime = [ l / k for k , l in zip( numpy.diff(P) , numpy.diff(I) ) ]
fig = plt.figure()
ax1 = fig.add_subplot(211)
ax2 = fig.add_subplot(212)
ax1.plot(P,I)
ax2.plot(P[:-1],Iprime)
fig.savefig( fname + ".pdf", format='pdf' )
```
And it seems the longer operation is to import matplotlib.pyplot.
Does something could be done to improve the loading time of this module ?
Thank you very much.
greatings,
David Kremer
