[Matplotlib-users] hatching problem

[Tomasz Koziara]

Dear Users/Developers




I will appreciate some hints on how to get by,

===================

I just installed version 0.99.1.1 since in my previous version (0.98) I had problems with hatching. It seems though that the same problems persist in the current version. The attached files reproduce the problem (a data file and a python short script). Note that hatching is not present on all green 'CONUPD' fields - but only on few of them.

cubes_1_PSEUDO_RIGID_FULL
Description: Binary data

#!/usr/bin/env python
# a stacked bar plot with errorbars
import numpy as np
import matplotlib.pyplot as plt

inp = open ("cubes_1_PSEUDO_RIGID_FULL", "r")
dat = [[],[],[],[],[],[],[],[],[],[],[]]
lin = inp.readline ()
num = 0
while lin != "":
  lst = lin.rsplit (" ")
  lin = inp.readline ()
  if len (lst) > 2:
    dat [num % 11].append (float (lst [2]))
    num = num + 1

N = 8
TIMINT = np.array (dat [0])
CONUPD = np.array (dat [1])
CONDET = np.array (dat [2])
LOCDYN = np.array (dat [3])
CONSOL = np.array (dat [4])
PARBAL = np.array (dat [5])
ind = np.arange(N)
width = 0.6

p1 = plt.bar (ind, TIMINT, width, color='r')
p2 = plt.bar (ind, CONUPD, width, color='g', bottom=TIMINT, hatch='//')
p3 = plt.bar (ind, CONDET, width, color='b', bottom=TIMINT+CONUPD, hatch='.')
p4 = plt.bar (ind, LOCDYN, width, color='y', bottom=TIMINT+CONUPD+CONDET, hatch='o')
p5 = plt.bar (ind, CONSOL, width, color='c', bottom=TIMINT+CONUPD+CONDET+LOCDYN, hatch='*')
p6 = plt.bar (ind, PARBAL, width, color='m', bottom=TIMINT+CONUPD+CONDET+LOCDYN+CONSOL, hatch='O')

plt.ylabel ('Time [s]')
plt.title ('Runtimes by processor count')
plt.xticks (ind+width/2., ('1', '2', '4', '8', '16', '32', '64', '128') )
plt.legend ((p6[0], p5[0], p4[0], p3[0], p2[0], p1[0]), ('PARBAL', 'CONSOL', 'LOCDYN', 'CONDET', 'CONUPD', 'TIMEINT'), loc = "upper left")
plt.axis (xmin = -0.2, xmax = ind[N-1]+width+0.2)
plt.savefig ('cubes-1-prb-full.eps')
plt.clf ()
