Sometimes the solution is embarrassing simple.
Thanks a lot, I did not get that before :)

There is no requirement that the arguments be on a grid; x, y, u, and v 
can simply be 1-D arrays with the desired locations and values.

basemap's barbs is a mapping wrapper around matplotlib's Axes.barbs() 
method, so you can use either one depending on whether you want to plot 
on a map projection or on some other x,y coordinates.

[Matplotlib-users] Help with updating the limits of an axis to reflect the range of new data

2015-03-25 Thread rogerjames99 
Hi,

I am trying to draw a polar plot of a sonar scan. The idea being to present
it like a radar display. I have used axisartist to do the ploar plot. This
is working fine but I would like to reset the limits of the radius axis with
each new scan. I have tried a number of ways of doing this without success.
My current code to set up the plot looks like this.



and to update the plot. Like this


I have tried doing the above on the host axes and the auxiliary one and with
different parameters to the relim etc. Nothing seems to work. Before I tried
various other calls to manipulate the extremes but with the same lack of
results. Can anyone set me straight on this? I feel I must be missing
something obvious. However I find the documentation and the class
inheritance hierarchy almost impossible to follow.

Here are a couple of links to snapshots of the output.

Before

  

After

  

Thanks,

Roger

[Matplotlib-users] Wind barb plot for a single station data

2015-03-25 Thread Foehn 
Hello all,

the routine barbs(x,y,u,v) in basemap plots a regular 2-dimensional 
vector field for a geographic projection.

What I want is a barb-routine that plots single station wind data (and 
not fields!) at their approriate lat,lon or x,y-position like in a 
station plot on a synoptic weather-chart. I googled and searched a 
while, but I could not find a solution within basemap for that.

Can you help me?


Thanks, Foehn
