Hi,
What about ordering the arrays before plotting ? Are the first elements drawn
back to front ?

Subject: [Matplotlib-users] zorder for individual points in a scatter plot on a
Basemap
Hi,
I'm currently using a scatter plot on a Basemap and I'd like to set the zorder
of the individual points based on their temperature. The higher the
temperature, the higher the zorder. Also, i'm using a colorbar to set the
colors for the plot. Here is a snippet of my code:
x = np.array(val)
fig.sca(ax1)
lon_0 =(urcrnrlon+llcrnrlon)/2
lat_0 =(urcrnrlat+llcrnrlat)/2
m =
Basemap(llcrnrlon=llcrnrlon,llcrnrlat=llcrnrlat,urcrnrlon=urcrnrlon,
urcrnrlat=urcrnrlat,resolution='i',projection='cyl',lon_0=lon_0,lat_0=lat_0)
m.drawcoastlines()
m.drawmapboundary()
m.drawparallels(np.arange(llcrnrlat-1,urcrnrlat+1,5.))
m.drawmeridians(np.arange(llcrnrlon-1,urcrnrlon+1,5.))
m.fillcontinents(color='white',lake_color='aqua')
m.drawcountries(linewidth=1)
lons,lats = m(lon,lat)
#I can do it this way, but this screws up the colorbar
#for i in range(len(x)):
# m.scatter(lons[i],lats[i],c=x[i],marker='o',picker=5,zorder=x[i])
m.scatter(lons,lats,c=x,marker='o',picker=5)
plt.title('Time Range: %s to %s'%(startDay.strftime("%b-%d
%H:%M"),endDay.strftime("%b-%d %H:%M")))
plt.colorbar(shrink=0.5)
Is there anyway to set the zorder of the points without using the loop in
commented code? Any help would be greatly appreciated.
Thanks,
Aman
