漂亮的阴谋条形图python与matplotlib
问题描述:
我写了一个python代码下面为我的数据绘制条形图。我调整了参数但未能使它变得美丽(见附图)。漂亮的阴谋条形图python与matplotlib
的Python代码如下所示:
def plotElapsedDis(axis, jvm1, jvm2, ylabel, title, name):
import matplotlib.pyplot as plt
import numpy as np
#fig, ax = plt.subplots(111)
fig = plt.figure()
ax = fig.add_subplot(111)
## the data
N = len(jvm1)
#menMeans = [18, 35, 30, 35, 27]
#womenMeans = [25, 32, 34, 20, 25]
ind = np.arange(N)+1
width = 0.25 # the width of the bars
rects1 = ax.bar(ind-width, jvm1, width)
rects2 = ax.bar(ind, jvm2, width, color='r')
ax.set_ylabel(ylabel)
ax.set_title(title)
plt.xticks(ind , axis, rotation=-90)
ax.legend((rects1[0], rects2[0]), ('Originl', 'Optimal'))
plt.savefig(name)
plt.close()
plotElapsedDis(keys, y_jvm1, y_jvm2, 'seconds', 'CPU Elapsed', '../tmp/cpu_elapsed.jpg')
前三列出plotElapsedDis是:

- x-aixs的标签太长,会被截断(超出图形边界)。
- 用别人的颜色来区分酒吧。由于图片将被打印,因此按颜色区分将不起作用。如何填写不同风格的组(例如,figure中的最后一个栏)。
如果有人能帮助调整此照片的前景,我将不胜感激。谢谢!

我会考虑清理一下名称,这应该有所帮助。一旦你这样做,你可以改变旋转到45
这将使它看起来更好。
你可以通过改变plt.xticks(ind , axis, rotation=90)
到plt.xticks("range", "custom label list", rotation=90)
def plotElapsedDis(axis, jvm1, jvm2, ylabel, title, name):
import matplotlib.pyplot as plt
import numpy as np
#fig, ax = plt.subplots(111)
fig = plt.figure()
ax = fig.add_subplot(111)
## the data
N = len(jvm1)
#menMeans = [18, 35, 30, 35, 27]
#womenMeans = [25, 32, 34, 20, 25]
ind = np.arange(N)+1
width = 0.25 # the width of the bars
# add "hatch"
rects1 = ax.bar(ind-width, jvm1, width, color='white', edgecolor='black', hatch="*")
rects2 = ax.bar(ind, jvm2, width, color='white', edgecolor='black', hatch='//')
ax.set_ylabel(ylabel)
ax.set_title(title)
plt.xticks(ind , axis, rotation=90)
ax.legend((rects1[0], rects2[0]), ('Originl', 'Optimal'))
fig.tight_layout() # make sure it fits
plt.show()
plotElapsedDis(keys, y_jvm1, y_jvm2, 'seconds', 'CPU Elapsed', '../tmp/cpu_elapsed.jpg')
你不应该混合对象API('ax.legend()')与MATLAB般的API('PLT。 xticks','plt.savefig')。你可以通过调用'fig.tight_layout()'来解决你的标签问题 – MaxNoe
