I was having some issues tonight getting a colorbar to function
properly. If my script simply looked like so:
fig=figure(figsize=(12,6))
p1=fig.add_subplot(121)
column_render(datasets[0],PICKER,logData=LOG,
minIn=datasets[COLOR_SCALE].MIN, maxIn=datasets[COLOR_SCALE].MAX)
axis([XL,XH,YL,YH])
title(r'VSPH')
p2=fig.add_subplot(122)
column_render(datasets[1],PICKER,logData=LOG,
minIn=datasets[COLOR_SCALE].MIN, maxIn=datasets[COLOR_SCALE].MAX)
p2.set_yticklabels([])
axis([XL,XH,YL,YH])
title(r'DISPH')
subplots_adjust(wspace=0,hspace=0,right=0.85,left=0.07)
cb = colorbar()
cb.set_label(r'%s' % datasets[COLOR_SCALE].LABEL,fontsize=18)
show()
I got something that looked like this:
which is obviously not what I was looking for. Apparently I need to
add an axis where I will place the colorbar. Tips from
stackoverflow
and checking out python’s
website itself led me
to the proper conclusion:
fig=figure(figsize=(12,6))
p1=fig.add_subplot(121)
column_render(datasets[0],PICKER,logData=LOG,
minIn=datasets[COLOR_SCALE].MIN, maxIn=datasets[COLOR_SCALE].MAX)
axis([XL,XH,YL,YH])
title(r'VSPH')
p2=fig.add_subplot(122)
column_render(datasets[1],PICKER,logData=LOG,
minIn=datasets[COLOR_SCALE].MIN, maxIn=datasets[COLOR_SCALE].MAX)
p2.set_yticklabels([])
axis([XL,XH,YL,YH])
title(r'DISPH')
subplots_adjust(wspace=0,hspace=0,right=0.85,left=0.07)
cax = fig.add_axes([0.86, 0.1, 0.03, 0.8])
cb = colorbar(cax=cax)
cb.set_label(r'%s' % datasets[COLOR_SCALE].LABEL,fontsize=18)
show()
by adding an axis for the colorbar to live on lets me customize its
location, width, and height. The parameters in
add_axis([left,bottom,width,height]) as in it’s drawing a rectangle.
With this slight change the plot now looks like this:
