Question

我有一个滑动条，用于绘制CSV文件的行。滑块功能正常，将返回正确的值。但是，我无法将值显示在图表上。绘制散点图（有4个点）和插值曲面有两点。散点图按预期显示。这是更新代码：

def update (val):
    ax.clear()
    val=int(val)
    new=a[val]
    canvas1.blit(axsigma.bbox)
    ax.scatter(x, y, marker='o', s=256, lw=.1)
    xi, yi = np.mgrid[x.min():x.max():500j, y.min():y.max():500j]
    newi = griddata(x,y,new,xi,yi, interp='nn')
    CS = plt.contourf(xi,yi,newi,500,cmap='jet', vmax=5, vmin=0) ##This line should plot the new temperatures
   ax.relim()
   ax.autoscale_view(True,True,True)

任何建议都将不胜感激。提前谢谢！

Answer 1

def update (val):
    ax.clear()
    val=int(val)
    new=a[val]
    canvas1.blit(axsigma.bbox) 
    xi, yi = np.mgrid[x.min():x.max():500j, y.min():y.max():500j]
    newi = griddata(x,y,new,xi,yi, interp='nn')
    CS = ax.contourf(xi,yi,newi,500,cmap='jet', vmax=M, vmin=m) ##change plt to ax
    ax.scatter(x, y, marker='x', c='k', s=36)  ## move to end so scatter is on top of surface

如果轴对所有数据保持不变，也没有理由调整轴的大小
