I have to plot a set of totally separate and independent plots, and then adjust their ylim values so they can be easily visually compared. How can I retrieve the ylim values from each plot, so that I can take the min and max of the lower and upper ylim values, respectively, and adjust the plots so they can be visually compared?

Of course, I could just analyze the data and come up with my own custom ylim values Any suggestions on how to easily and efficiently do this? Just use axes. From the docs :. The above code should produce the following output plot. It's an old question, but I don't see mentioned that, depending on the details, the sharey option may be able to do all of this for you, instead of digging up axis limits, margins, etc.

There's a demo in the docs that shows how to use sharexbut the same can be done with y -axes. Learn more. Asked 6 years ago. Active 3 days ago. Viewed k times.

I'm writing a little app in wxPython which has a matplotlib figure using the wxagg backend panel.

I'd like to add the ability for the user to export X,Y data of what is currently plotted in the figure to a text file. Is there a non-invasive way to do this?

I've searched quite a bit and can't seem to find anything, though I feel like it is incredibly simple and right in front of my face. I could definitely get the data and store it somewhere when it is plotted, and use that - but that would be fairly invasive, into the lower levels of my code.

It would be so much easier, and universal, if I could do something as easy as:. Writing to the text file after that is trivial.

I found these by digging around in the axis object. I could only find some minimal information about these functions, apperently you can give them a boolean flag to get either original or processed data, not sure what the means. Learn more.

Implementation of matplotlib function import numpy as np import matplotlib.The projection type of the Axes. The default None results in a 'rectilinear' projection. The axis will have the same limits, ticks, and scale as the axis of the shared axes.

The returned axes class depends on the projection used. It is Axes if rectilinear projection is used and projections. PolarAxes if polar projection is used. This method also takes the keyword arguments for the returned axes class.

The keyword arguments for the rectilinear axes class Axes can be found in the following table but there might also be other keyword arguments if another projection is used, see the actual axes class.

If the figure already has a axes with key argskwargs then it will simply make that axes current and return it. This behavior is deprecated. Meanwhile, if you do not want this behavior i. The axes label attribute has been exposed for this purpose: if you want two axes that are otherwise identical to be added to the figure, make sure you give them unique labels.

Property Description adjustable.Axes object is the region of the image with the data space. A given figure can contain many Axes, but a given Axes object can only be in one Figure. The Axes contains two or three in the case of 3D Axis objects. The Axes class and its member functions are the primary entry point to working with the OO interface.

It returns the axes object and adds an axes at position rect [left, bottom, width, height] where all quantities are in fractions of figure width and height. The legend method of axes class adds a legend to the plot figure. Where labels is a sequence of strings and handles a sequence of Line2D or Patch instances. This is the basic method of axes class that plots values of one array versus another as lines or markers.

The plot method can have an optional format string argument to specify color, style and size of line and marker. Following example shows the advertisement expenses and sales figures of TV and smartphone in the form of line plots.

Line representing TV is a solid line with yellow colour and square markers whereas smartphone line is a dashed line with green colour and circle marker. Matplotlib - Axes Class Advertisements.
