Code Block
    
plt.title('Image',color='b',fontsize=20)
or
axes.set_title('Image',color='b',fontsize=20)

Log scale methods

Log values:

Code Block
    
from math import log10
log_vmin, log_vmax = log10(vmin), log10(vmax)

Log scale axes:

Code Block

axes.set_xscale('log')
axes.set_yscale('log')

Log scale image data:

Code Block

self.arr2d = np.log10(self.arrwin)
self.imsh = axis.imshow(self.arr2d, origin='upper', \
                                          interpolation='nearest', \
                                          extent=self.range, aspect='auto')
self.imsh.set_clim(log_vmin,log_vmax)

Histogram with log statistics (y axis):

Code Block

axes.hist(self.arrwin.flatten(), bins=self.nbins, range=self.range_his, log=True)

Plot histogram with log bin size:

Code Block

logbins=10**np.linspace(log_vmin, log_vmax, nbins)
# or:
logbins=np.logspace(log_vmin, log_vmax, nbins)
self.axhi.hist(self.arrwin.flatten(), bins=logbins )

Window title

Code Block
    
    fig.canvas.set_window_title('Image And Spectrum ' + u'\u03C6')
