[Matplotlib-users] preventing scaling view after updating plot
(mpl 0.98.5 OO embedded in wx) Hi, I'm trying to highlight a picked datapoint, such as is shown in this thread: http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/msg05580.html As John suggested there, I get the index of the picked point, and then plot a marker on that point. I am using the OO mpl form, so then I call, to draw this new point on the canvas: self.canvas.draw() (self.canvas is a figure.canvas object). But when I do this it *rescales the plot*, which I don't want. In this thread: http://www.nabble.com/Re%3A-Plotting-single-marker-point-at-zoomed-level-p17511209.html I found someone mentioning this concern. He said: Thanks for that, the canvas.draw() function redraws the graph. I had to add the autoscale_on=False to the add_subplot() to stop the graph from autoscaling. I tried this, and it did stop autoscaling--but I do want y autoscaling. What I want is y autoscaling but not y autoscaling (just setting xlims). I tried adding either of these lines right before or right after when I plotted the highlighted point: self.subplot.set_autoscale_on(False) self.subplot.autoscale_view(tight=False, scalex=False, scaley=True) and it didn't help--the plot rescaled, both x and y. Any ideas what I'm doing wrong? Thanks, Che -- This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.

I tried adding either of these lines right before or right after when I plotted the highlighted point: Just to be clearer: What I want is the plot to stay precisely the same when I add the highlighted point. But now I have either of two undesired alternatives: 1) I do add_subplot(111,autoscale_on=False) when I create the subplot and none of my plots have the y scaled (but I want them scaled). 2) I do add_subplot(111) and when I add a highlighted datapoint it autoscales my plot (but I don't want that).

If you upgrade to SVN head, it supports what you want. You can use: add_subplot(111, autoscalex_on=False) I don't think this particular feature has made it into a release yet.

I'll try to get it from SVN or back-burner this issue until the next release. Che -- This SF.net email is sponsored by: High Quality Requirements in a Collaborative Environment.
