Thank you.

Let's see if someone wants to adapt it for direct inclusion in mpl, or 
as an example.  I'm not going to volunteer, since it is far from my area 
of expertise, and I am short of time anyway.

Hi Eric,

Thanks agaon. Now it works after updating to matplotlib 98.5.

Well I also attach the code. I find it good if we can publish it to other
interested users. May be some one needs it or likes to upgrade it. I made
already the basic work. How does this work? Should I distribute it via the
list here or somewhere else?

I am not expert in this stuff :)

Nice wishes,
Sherif

It looks like support for the resolution kwarg was added late in 
January, so you need either a more recent version, or an older version. 
  Unfortunately, it also looks like the latest release was before this 
change.

Maybe it is time for another release, either 0.98.5 maintenance or 
trunk. Or both. Releases are not my area, though.

Do you know what is the reason behind this?

Put the resolution kwarg in the call to the add_axes method.  The way 
the line is drawn between points--whether as a straight line on the plot 
or by interpolating in the data coordinates--is controlled on a per-axes 
basis by this kwarg when the axes are created.
