How can a pie chart be drawn with Matplotlib with a first wedge that starts at noon (i.e. on the top of the pie)? The default is for pyplot.pie() to place the first edge at three o'clock, and it would be great to be able to customize this. ...
I'm trying to display a grayscale image using matplotlib.pyplot.imshow(). My problem is that the grayscale image is displayed as a colormap. I need the grayscale because I want to draw on top of the image with color. I read in the image and convert to grayscale using PIL's Image.open().convert("L") image = Image.open(file).convert(...
I'd like to annotate a plot in matplotlib with filled and non-filled dots. I can create a circle patch, but the circle scales with my axes which is not my desired effect. I can achieve this with plt.plot(x,y,'.',markersize=10) plt.plot(x,y,'o',markersize=10) but both markers are filled even if I set markerfacecolor=None. ...
Dear all, I'm trying to perform a scatter plot with color with an associated color bar. I would like the colorbar to have string values rather than numerical values, as I'm comparing two different data sets each one with different colorvalues (but in any case between a maximum and minimum values). Here the code I'm using import matplotl...
Hi guys! I've been googleing to find if it's possible to change only the color of a bar in a graph made by matplotlib. Imagine this graph: let's say I've evaluation 1 to 10 and for each one I've a graph generate when the user choice the evaluation. For each evaluation one of this boys will win. So for each graph, I would like to leav...

I have this beautiful sphere I made in matplotlib. How would I go about putting it in a tkinter frame widget? It'd be nice to be able to integrate it into an existing tkinter GUI. Also is it possible to rid of the menu bar below the display? I have no need to save the output or zoom, so it's useless to me. from mpl_toolkits.mplot3d imp...
