try using plot_date() function instead of plot()

Hi,
I've coded (with help from John) a plot of mine to allow a user to
select a data point, and when they click on it a new plot pops up. It
works great. However, some of the points are very close together and if
I'm not extremely careful in selecting the point, then multiple graphs

Sorry for the repost, but I'm still struggling with this.
I'm trying to replicate a plot like this:

In this case, the y-axis on the left (the black dots) is linear
and the y-axis on the right (red data) is log base 2.
I can't figure out how to do the following:

Coming from MATLAB, I started using matplotlib in the same fashion (and
was very appreciative of the similariry). That is, I would import pylab
and call the plotting functions as necessary. However, after seeing
some of how others are using matplotlib, it seems most people use axes
object methods
Excellent. Thank you very much!

Hi,
Please look at the short example attached showing the issue.
I want to display only one contour line, with value 0.8.
Obviously, the color associated with this contour line is bad
(blue instead of red color).
I think the reason is that the contour has its own colormap,
so for only one valu

Hello darkside,
the below example seems to do the job.
The problem with x, y = event.xdata, event.ydata could be due to a
local-global-variable issue (solution: define x, y with keyword global,
i.e. "global x, y" in your function 'click' [ -> they become global
variables] to change their value

Hi, thanks, yes infact wind barbs it's difficult to plot with quiver I have
to coding something appropiate.
So ,just I HAVE FOR THE MOMENT TO PLOT ONLY A LEGEND with one wind vector
that have a lenght autoscale
Works for me.
Thanks, Mark
