[Matplotlib-users] Arrow Questions

2008-08-14 Thread Ben Axelrod
I am trying to implement a dynamic graph in mpl, where users can drag around the nodes, and the edges follow the nodes like rubber bands. I have this working with regular edges, but I want to give the option of putting arrows on the edges. I am running into some issues with the Arrow classes.

Hi Mathieu, It seems to me that you're confused with the meaning of the transAxes. It is a transform from the Axes coordinate to the Canvas(?) coordinate. As far as I can see, what you seemed to want is a transform between Data coordinate and Axes coordinate, and that would be transScale + transLi

I am still investigating and I am stuck at converting transAxes values to data. If my axes goes from 10.0 to 20.0 then transAxes 0.5 should give me 15.0. This would allow me to compute bar width and space, since I am able to convert inches to transAxes values. I tried many combinations of transA

Hi, Sorry for the long delay - I have been on vacation. I don't use the imcrop function, but it looks fairly easy to implement using ginput. I am heading off for vacation again for another two weeks and I want to get in some of the changes I proposed a long while ago before working on this, so i
