在matplotlib中制作交互式滑块？

Question

我有以下代码：

def plotter(x,y,w,h,n,list1):
    randomList = randFunc(list1,x,y,w,h,n)
    xlist = np.arange(2/(2*n),w,2/n)
    ylist = np.arange(2/(2*n),h,2/n)
    X,Y = np.meshgrid(xlist,ylist)
    print(X)
    randomList = randomList[['x','y']].values.tolist()
    randomList = np.array(randomList)
    z = []
    for i in randomList:
        z.append(q_func(i[0],i[1]))
    z = np.array(z)
    z = np.reshape(z,(n,n))
    fig,ax2 = plt.subplots(1)
    ax2.pcolormesh(Y,X,z)

代码输出代表表面的彩色网格，但是我想创建一个交互式滑块来更改n的值，并将更新图形以反映此更改。我该怎么办？
