[Matplotlib-users] Using callbacks to change Axes positions

Hi, I am trying to set up a colorbar that automatically resizes if I zoom in to an image (which changes the aspect ratio of the axes, so I want the colorbar to get resized too). Let's say I have two Axes instances, say ax (for the main image) and cax (for the colorbar). I can set up a callback

[Matplotlib-users] Change colorbar orientation once drawn

Hi, I would like to change the orientation of a colorbar once it has already been drawn. So for example if I create the colorbar with: cb = fig.colorbar(mappable=image, cax=cax, orientation='vertical') I would like to be able to do cb.set_orientation('horizontal') Is there a way to do this, s

Re: [Matplotlib-users] Plotting boolean/logical data type

Not sure what exactly you want. Is this close? ax = subplot(111) tr = ax.get_xaxis_transform() ax.plot([0.2, 0.8], [0.5, 0.5], transform=tr) The x-coodinate is in data coordinate, but y coordinate is in (normalized) axes coordinate. More about the transforms behind matplotlib can be foun

Re: [Matplotlib-users] Transform problem with fixed aspect ratio

With axes aspect_ratio set, the position of the axes is determined during the drawing time. And the position of the inset axes also need to be adjusted during the drawing time to incorporate this, One way to archive this is to set axes_locator attribute, which accept a callable object that returns

[Matplotlib-users] Transform problem with fixed aspect ratio

Hi list - I've got a need to add several axes instances (e.g., barplots) to an existing figure. These additional axes need to be placed relative to data points on that plot. A problem occurs if the aspect ratio of the parent axes is set to a fixed value rather than using 'auto'. The attached scr

Re: [Matplotlib-users] Older Version of Matplotlib for Python 2.2.1

what kind of errors did you get when building on windows? I recently found out that Visual Studio is required to build MPL on windows. This is because MPL contains C++ sources. Additionally, you must have the same version of Visual Studio that was used to build Python. So if you installed py

Hey All, I have a fig, see attach image. I am plotting the number of infected nodes versus time. Time is running from 0 to 100. I need to insert a subplot in that figure that shows me the number of infected nodes for time running from 0 to 20 for example. If there is an example that can do the s
