[Matplotlib-users] Multiplot with one colorbar

[Dyah r. m. <dya...@gm...>]

Hello all,

I make multi plot with colorbars. I need help, how do make only one
colorbar for six panels? I also want to show only lowest x-axis. I copy my
recent code and  figure here.

   # Open file
    fd = nc.Dataset(fname, 'r')

    # Read variables
    beam = fd.variables['beam'][:]
    rng = fd.variables['range'][:]
    tim = fd.variables['time'][:]
    pwr = fd.variables['pwr'][:]
    nfft = fd.variables['nfft'][0]
    pn = fd.variables['pnoise'][:]
    width=fd.variables['width'][:]
    # Close netCDF file
    fd.close()

    # Specify beam
    ibeam = ibeams[i]

    # Time convertion
    tim = tim/3600.0

    #Plot
    p_plot = pwr[ibeam]
    for it in range(len(tim)):
        p_plot[it] = p_plot[it] - pn[ibeam][it] - 10.*np.log10(nfft)
    p_plot = p_plot.transpose()

#Specify subplot
    pl.subplot(611 + i)
#Contour plot
    v= np.linspace(5., 50., 5., endpoint=True)
    x= pl.contourf(tim, rng, p_plot, v, cmap=pl.cm.jet)
    x = pl.colorbar(ticks=v)
    x.ax.set_title('dB')
    print x


# Set X and Y axis lower/uppser limit
    set_xy = range(4)
    set_xy[0] = 18.0 # x min
    set_xy[1] = 30.0 # x max
    set_xy[2] = 200.0 # y min
    set_xy[3] = 550.0 # y max
    pl.axis(set_xy)

# Set labels
    pl.xlabel('time (hours)')
    pl.ylabel('range (km)')
    pl.show()


Thank you....
