Adapt stem plot #10165
Description
Proposed changes
Inspired by the example stem plot.
1. Z order
Currently the stems are on top of the markers. This is in agreement with the MATLAB behavior http://de.mathworks.com/help/matlab/ref/stem.html#btrw_xi-94
However, it looks a bit untidy. I propose to place the markers on top.
2. Example coloring
The example cycles through the stem colors. IMO this is an untypical use case. The example (in particular if we just have one) should show a typical diagram. Therefore, we should change it to just one stem color.

I would also argue that it should be considered a bug that
ax.stem([1, 2])does not cycle the colors butax.stem([1, 2],"-.")does... not sure if #9565 helps with that.AdamsonMA commentedon Feb 4, 2018
I've also found that the lines overlapping the markers looked untidy. My solution was to create a new pyplot method for personal use that allows users to re-order which items appear on top when plotting. I would be glad to share the code if this issue is still open!
An example of the reordered plot:

It seems that #9565 (comment) also fixes the z-order. To prevent duplicate work, I wouldn't do anything here until the above is merged.

I mildly disagree about the zorder. Its easier to pick off a precise number when a solid line ends at the end to the stem.

Ok, let's keep the zorder.
The example coloring is adapted in #13687.
