[Matplotlib-users] Unusual (?) spacing with sub-/superscripts
Hello everyone,
I frequently use subscripts and superscripts in text on my plots, but
I've noticed that the line and character spacing (kerning ?) is not
always as I would expect. For most things, this is not a problem.
However, I would occasionally like various text objects to line up with
one another, and at these times, this spacing difference can become a issue.
I guess I have a couple questions at this point... First, is this
expected? Second, is there any (simple) way I can control the line and
character spacing? I see there is a 'linespacing' keyword argument;
however, this seems to be a multiplier relative to the total text height
for each line not an absolute, fixed height of every line. For character
spacing, is there a special symbol I could insert to add or removing
spacing between characters?
I'm using Matploblib 1.0.0 that ships with Python(x,y) for Windows.
Below is a test script that highlights these differences (at least on my
system).
Any help or suggestions are most appreciated. (I don't know much TeX, so
I appologize if these differences are obvious for those in the know.)

import matplotlib.pyplot as plt
plt.rc('font', size=25.0)
plt.text(0.25, 0.25,
'X1Y2\nX1Y2\nX$_1$Y$_2$\nX$_{1}$Y$_{2}$\n$X_1Y_2$\n$X_{1}Y_{2}$')
plt.text(0.75, 0.25,
'X1Y2\nX1Y2\nX$^1$Y$^2$\nX$^{1}$Y$^{2}$\n$X^1Y^2$\n$X^{1}Y^{2}$')
plt.text(0.5, 0.25, 'X$_{1}$Y$_{2}$\nX$^{1}$Y$^{2}$\n$X_1Y_2$\n$X^1Y^2$')
plt.show()

Re: [Matplotlib-users] clearing previous format changes
Ben, Sorry to take so long getting back. I found a solution. Perhaps not the best one but I discovered that using close() after a show() or save() worked for me.

[Matplotlib-users] Analog of processing map() or protovis scale?
Hi all, Does there already exist some python implementation (in MPL or other) of an easy-to-use 1D scale transformation? This is something analogous to processing's map function or protovis's scale functionality. It would work something like: s = linear().domain(5,100).range(13000,15000) or s = root(p=5).domain(0.1,0.6).range(0,1) There could be multiple versions, including linear, log, symlog, root (power), discrete, etc. Thanks!

Both of these do end up with an inverse method that you could leverage to get an arbitrary range, though. 1. http://matplotlib.sourceforge.net/api/colors_api.html#matplotlib.colors.Normalize 2. http://matplotlib.sourceforge.net/api/colors_api.html#matplotlib.colors.LogNorm -- Paul Ivanov 314 address only used for lists, off-list direct email at: http://pirsquared.org | GPG/PGP key id: 0x0F3E28F7 signature.asc Description: Digital signature -- Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.

[Matplotlib-users] autofmt_xdate and twinx?
Hi from what I can see if I call fig.autofmt_xdate() with a the twinx command the xaxis labels do not roatate as you might expect. There seem to be a few threads on this e.g. http://old.nabble.com/autofmt_xdate()-broken-for-twinx()-p30248577.html However does anyone know a workaround until there is a later version available?
