Problem

Animate decay claims it shows how tochanging axes limits during an animation in the run method

defrun(data):# update the datat,y=dataxdata.append(t)ydata.append(y)xmin,xmax=ax.get_xlim()ift>=xmax:ax.set_xlim(xmin,2*xmax)ax.figure.canvas.draw()line.set_data(xdata,ydata)

but the limits aren't actually changing:

Suggested improvement

Either option is fine with me:

• fix code so xlims dynamically updated
• remove lim updating code and statement saying this example shows how to update limits
