python - Matplotlib widget - many radiobuttons issue -

i need set height of matplotlib widget, change alignment or change font don't know how.

screenshots:

5 radio buttons:

15 radio buttons:

and here critical code part:

def evolvecallback_(self, notification):     global     stats={}     results=[]     fitnesses=[]      code,fit in evolve(i):         results.append(code)         stats[str(fit)]=code         fitnesses.append(str(fit))     i+=1     fig = plt.figure()      done=""      if found():         done=" - solution found!"         print "done!"      fig.canvas.set_window_title("generation "+str(i)+". - best migrating individuals"+done)        ax = plt.subplot(111)     ax.set_title(stats[str(fitnesses[0])])     l, = ax.plot(x, s0, lw=2, color='blue')     plt.subplots_adjust(left=0.4)      axcolor = 'lightgoldenrodyellow'     rax = plt.axes([0.05, 0.7, 0.15, 0.15], axisbg=axcolor)      radio = radiobuttons(rax, tuple(fitnesses))     def change(label):         hzdict = {}         x = np.arange(-5.0, 5.0, 0.01)         j=0         in tuple(results):             hzdict[fitnesses[j]]=eval(i)             j+=1         ax.set_title(stats[str(label)])         ydata = hzdict[str(label)]         l.set_ydata(ydata)         plt.draw()     radio.on_clicked(change)     plt.show() 

this line sets , how big axes radio buttons drawn onto is:

rax = plt.axes([0.05, 0.7, 0.15, 0.15], axisbg=axcolor) 

change like

rax = plt.axes([0.05, 0.3, 0.15, 0.5], axisbg=axcolor) 

(doc)

to clear, rax axes object adding radio button widgets to.
