Hi all, I ran into a problem where I wanted to plot a step-plot with dashed lines instead of solid lines which can be important for print media. This isn't possible with the current matplotlib version, so I added support for this. The patch is attached, but I didn't commit it yet since I wanted to ask for feedback first. It basically adds support to do pylab.plot(x, y, 'steps--') to create a step plot with dashed lines. mm

This needs to be fixed ... mm
Hi all, I think I have finally found a nice way to implement step-plots with different linestyles. The way this is done required some re-writing of lines.py, but I think it is done in a consistent manner: A new property *drawstyle* is introduced. By default this just connects the datapoints by a straight line. It can be set to "steps-***" to create step-plots. So, the important point is that "steps-***" is no longer a linestyle and thus it is possible to set the linestyle independently. Additionally one can set a combined line- and drawstyle, e.g. linestyle='steps-mid:'. The drawstyle property has the advantage, that one can add other ways to draw the data naturally, for example one can think of a drawstyle "bspline" that connects data-points using a spline, or something like a moving-mean plot. The patch is applied and also an example and its output. If there are no objections, I will commit the patch soon. Any comments ??? Manuel
