RE: [pyngl-talk] closing an x11 window

Fred,

That did the trick. Happy Holidays.

Thanks,

John,

Try Ngl.destroy(wks). This will kill the
workstation, so if you want to draw into
another window, you will have to open another
workstation. For example:

import Ngl

x = [10., 20.00, 30., 40.0, 50.000, 60.00, 70., 80.00, 90.000]
y = [ 0., 0.71, 1., 0.7, 0.002, -0.71, -1., -0.71, -0.003]

wks = Ngl.open_wks("x11","ngl01p") # Open a workstation.
plot = Ngl.xy(wks,x,y) # Draw an XY plot.
Ngl.destroy(wks) # Remove the X11 window.

x = [10., 20.00, 30., 40.0, 50.000, 60.00, 70., 80.00, 90.000]
y = [ 0., 0.31, 1., 0.3, 0.002, -1.01, -2., -0.71, -0.003]

wks = Ngl.open_wks("x11","ngl01p") # Open a workstation.
plot = Ngl.xy(wks,x,y) # Draw another XY plot.
