If you just want to set them to a single color, use the error_kw kwarg (expected to be a dict of keyword arguments that’s passed on to ax.errorbar). Also, just so you know, you can pass a sequence of facecolors directly to bar, though this won’t change the errorbar color. As a quick example: import … Read more
If you create the figure without using plt.figure, then it should be reference counted as you expect. For example (This is using the non-interactive Agg backend, as well.) from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas from matplotlib.figure import Figure # The pylab figure manager will be bypassed in this instance. # This means that `fig` will … Read more
Not a real answer but a workaround, as suggested by Tom Augspurger, is that you can just use the working line plot type and specify dots instead of lines: df.plot(x=’x’, y=’y’, style=”.”)
For Arabic you need both bidi.algorithm.get_display and arabic_reshaper modules: from bidi.algorithm import get_display import matplotlib.pyplot as plt import arabic_reshaper reshaped_text = arabic_reshaper.reshape(u’لغةٌ عربيّة’) artext = get_display(reshaped_text) plt.text(0.25, 0.45, artext , name=”Times New Roman”,fontsize=50) plt.show()
You can use axhspan and/or axvspan like this: import matplotlib.pyplot as plt plt.figure() plt.xlim(0, 5) plt.ylim(0, 5) for i in range(0, 5): plt.axhspan(i, i+.2, facecolor=”0.2″, alpha=0.5) plt.axvspan(i, i+.5, facecolor=”b”, alpha=0.5) plt.show()
As you want to change the figure, instead of creating a new one, may I suggest the following way: Use an interactive backend; %matplotlib notebook Update the line in the plot, instead of drawing new ones. So the code could look something like this: %matplotlib notebook from ipywidgets import * import numpy as np import … Read more
This could work: import pylab fig = pylab.figure() figlegend = pylab.figure(figsize=(3,2)) ax = fig.add_subplot(111) lines = ax.plot(range(10), pylab.randn(10), range(10), pylab.randn(10)) figlegend.legend(lines, (‘one’, ‘two’), ‘center’) fig.show() figlegend.show() figlegend.savefig(‘legend.png’)
pyplot is a sub-module of matplotlib which doesn’t get imported with a simple import matplotlib. >>> import matplotlib >>> print matplotlib.pyplot Traceback (most recent call last): File “<stdin>”, line 1, in <module> AttributeError: ‘module’ object has no attribute ‘pyplot’ >>> import matplotlib.pyplot >>> It seems customary to do: import matplotlib.pyplot as plt at which time … Read more
As tom suggested in the comment above, deleting the files: fontList.cache fontList.py3k.cache tex.cache solve the problem. In my case the files were under: `~/.matplotlib` EDITED A couple of days ago the message appeared again, I deleted the files in the locations mention above without any success. I found that as suggested here by T Mudau … Read more
There are several problems in your code. First the big ones: You are creating a new figure and a new axes in every iteration of your loop → put fig = plt.figure and ax = fig.add_subplot(1,1,1) outside of the loop. Don’t use the Locators. Call the functions ax.set_xticks() and ax.grid() with the correct keywords. With … Read more
