Hello everyone,
if I read a column file like this (simplified to integers):
0 1 2 3
1 2 3 4
2 3 4 5
3 4 5 6
with: "data = np.loadtxt("fileName")", why can't I use a for loop inside
ipython (started with "-pylab" option) to plot each of the Line2D objects and
then draw them on the plot? I am using matplotlib to debug a computational
geometry code and I would like these lines to plot paused by the user input so
that I can identify when (where) exactly the wrong calculations happen:
import numpy as np
import matplotlib.pyplot as plt
fig1 = plt.figure()
ax1 = fig1.add_subplot(111)
ax1.set_aspect("equal")
for line in data:
raw_input("press enter to plot the line")
ax1.plot([line[0],line[2]],[line[1],line[3]],'b')
plt.draw()
This way I could see with pressing e.g. the return key when my calculations go
wrong.... any advice?
