advaced scatter plot

Dear all, I was wondering if there is equivalent in python of this function:
PLOTCLR(X,Y,V) plots the values specified in V as a color coded scatter plot
at the locations specified in the vectors X and Y. The current colormap of
the figure is used for the color code. Any suggestions? Thanks.

"scatter" should do it

The update:
I was able to produce the plot with:

fig = P.figure()
ax = fig.add_subplot(1,1,1)
cmap = P.matplotlib.cm.jet
norm = P.matplotlib.colors.Normalsize(vmin=0,vmax=1)
sc = ax.scatter(ave_lon,ave_lat,c=v,cmap=cmap,norm=norm)
savefig('sg.png')

However, I have a few questions:
1.) How to control the size of each circle on the scatter plot
2.) How to add the coast line with lambert projection?
THANKS

Hi!

1.) How to control the size of each circle on the scatter plot

Use the “s” option to scatter (units are points**2)

2.) How to add the coast line with lambert projection?

You want to use the basemap extension. An example can be found in this blog: <http://stevendkay.wordpress.com/2009/10/12/scatter-plots-with-basemap-and-matplotlib/>

Cheers,
