While I am never in favor of dropping support for l packages just because they are old, if they are impeding adding good functionality because it is too difficult to code/test against too many interfaces, then by all means yes, we can drop <2.4. I thnk we could safely drop <2.6. JDH -- Register Now for Creativity and Technology (CaT), June 3rd, NYC. CaT is a gathering of tech-side developers & brand creativity professionals.

You are welcome Gus :) Go ahead and try these too.. I am assuming that you are experimenting in Ipython with --pylab. Use ? or ?? or browse and read for more information regarding to the usage of functions (http://matplotlib.sourceforge.net/api/pyplot_api.html) I am sure gallery has some extra demonstration, too setp(labels, 'rotation', 'vertical') xticklabels = getp(gca(), 'xticklabels') setp(xticklabels, fontsize=14, weight='bold') Have fun :) Gökhan On Sat, May 30, 2009 at 8:17 PM, W.

Possible, but I think there is a much better solution along the lines I suggested earlier. I have it partly implemented. To really do it right will require a little bit of work on all the interactive backends; it might be very little and very easy. It prompted my question starting another thread as to whether we can drop support for GTK < 2.4 so as to simplify that backend.

[Matplotlib-users] Stineman interpolation
Hi, Given that the values of ordinates are changing monotonically, I found that in some cases, stineman interpolation is monotonic even when the slopes are not monotonic. And in other cases, it overshoots. Like in the following one: x = (0, 10, 70, 100) y = (0, 535, 595, 1000) xx = arange(0,100,1) yy = stineman_interp(xx,x,y,yp=None) plot(x,y,'x') plot(xx,yy) Are there some factors that can make the interpolation monotonic, when the slopes are not monotonic? or does it depend on case by case basis? -- Register Now for Creativity and Technology (CaT), June 3rd, NYC.

Just to clarify -- by "readout" do you mean the toolbar strings? At first I was assuming that since the toolbar formatting picks up the tick Formatter to format the strings, and ScalarFormatter uses rcParams['axes.formatter.limits'] to determine when to fall over to scientific notation, that this setting would be picked up by the toolbar. The reason it does not is because ScalarFormatter overrides Formatter.format_data_short, which is what the toolbar uses via Axes.format_xdata/format_ydata, and ScalarFormatter.format_data_short does not use the formatter.limits setting. Are we at least on the same page now? If so, is it advisable/possible to make format_data_short respect the formatter.limits setting so Xavier can customize it to his heart's content.

You can control the point at which mpl falls over to scientific notation. From the matplotlibrc file (see http://matplotlib.sourceforge.net/users/customizing.html) axes.formatter.limits : -7, 7 # use scientific notation if log10 # of the axis range is smaller than the # first or larger than the second I'm actually surprised you are seeing problems with images of 1000x1000 -- it makes me suspect you have an older matplotlib version or an older matplotlibrc laying around because at -7,7, which is the current default, you should not see exponential formatting until you get to much larger sizes.
