如何使用 matplotlib 创建其帧共享常用颜色条的 GIF？

Question

I want to make a GIF animation of a wave propagation. My problem is the following: the colorbar should be constant for all the frames. How to make sure that the scale of the solution can be maintained from one frame to another, for the sake of readability?

Here is my code:

fig = plt.figure(figsize=(7,7))
fig = dolfin.plot(u)

plt.title(r'$u(\mathbf{x}, t)$')
plt.xlabel(r'$x$ [m]')
plt.ylabel(r'$y$ [m]')
plt.colorbar(fig, fraction=0.058, pad=0.04)
plt.savefig('fig'+str(n)+'.png',bbox_inches='tight', dpi=150)
plt.close()

Answer 1

As per my comments, you should just be able to add plt.clim(vmin,vmax) , or fig.set_clim(vmin,vmax) , as necessary.
