Problem

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

def run(data):
    # update the data
    t, y = data
    xdata.append(t)
    ydata.append(y)
    xmin, xmax = ax.get_xlim()

    if t >= 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
