Re: [matplotlib-devel] Selecting all the way to the edge of a plot
I'd like to throw another vote in for this feature as well. We have a lot of cases like this and not being able to zoom to the limits of the window is a real head ache. Back in the old days (when we were maintaining our own plot library), we solved this by allowing the bounding rectangle to be drawn outside the figure (assuming the mouse started inside the figure). When the mouse is released, the limits are reduced by the current axes values before applying the zoom. Something like: - mouse click outside the figure - handle like normal - mouse click inside the figure - start zooming - mouse drag - draw zoom box - mouse leaves figure - keep drawing zoom box (change from current havior) - mouse release - if mouse is outside figure zoom box started in, reduce zoom box to limits of axes (change from current behavior) - zoom Hope that helps...

Re: [matplotlib-devel] Selecting all the way to the edge of a plot
Rectangle selection also kind of bugs out when you reach the edge of the axes. I looked into fixing this a while ago and had a partial solution. The rectangle selector does some inaxes checking and relies on the xdata and ydata values. These are invalid outside the axes, but you can fake it by using the pixel values and a the axes transform. It might be worth adding a parameter to the rectangle selector to allow or disallow the rectangle to go outside of the axes. -Ben -Original Message- From: Anne Archibald [mailto:peridot.face...@gmail.com] Sent: Monday, March 22, 2010 11:39 AM To: Drain, Theodore R (343P) Cc: matplotlib-devel@lists.sourceforge.net Subject: Re: [matplotlib-devel] Selecting all the way to the edge of a plot On 22 March 2010 11:32, Drain, Theodore R (343P) theodore.r.dr...@jpl.nasa.gov wrote: I'd like to throw another vote in for this feature as well.

That way it is always called after you have done something. I like this approach better, because one problem with doing it in the mpl Artist layer is that one artist setter may call another, and trigger a series of calls to draw for what is only a single draw at the interactive prompt. ipython knows when an interactive call is made, and can issue a draw. The trick will be to manage something like a needdraw flag for all mpl figures, which is set when any property contained in that fiugure changed and flushed when any call to draw is made. If we maintain this flag on all mpl setters and flush it after all mpl draws, the ipython prompt hook could check the flag and draw if needed when interactive is True. Not sure it is worth the effort, since like JJ I tend to mostly use the pyplot functions when working from the interactive shell and don't mind calling draw when using the API. I don't think API usage should be encouraged for the interactive prompt -- but I don't think it should be discouraged either -- it's just that in practice most experienced users use the state machine in this case because it is less typing and we needn't be pedantic, even when teaching wink.
