问题描述
plt.figure(figsize = (10,8))
plt.scatter(x_range,y_range,s=1,c=Avgs,cmap = 'hot')
plt.colorbar().set_label('Avgs',fontsize=14)
plt.xlabel('x',fontsize=14)
plt.ylabel('y',fontsize=14)
plt.title('ToA heatmap',fontsize=17)
plt.show()
我正在尝试绘制一个8x8的网格，并且对于网格中的每个正方形，我希望基于相应的z列表获得颜色。对于“平均”列表，我遇到此错误：ValueError: Invalid RGBA argument: 978641729006.499
x和y仅为8x8：x_range = [*range(1,9)] y_range = [*range(1,9)]，z的长度为64。
我要使用的z值有问题吗？

解决方法
为了传递值数组，在您的情况下，create task mytask_hour
warehouse = COMPUTE_WH
schedule = '1 minute'
as
call TASK_();
与Avgs，c的形状必须与Avgs和x相同。在这种情况下，y不满足要求。
另一方面，Avgs的数据不必从0到1，它们的值会自动缩放：
imshow输出：
更新：用于您的数据：
Avgs = np.arange(256).reshape(16,-1) * 1000.001
plt.imshow(Avgs)
plt.colorbar().set_label('Avgs',fontsize=14)
plt.xlabel('x',fontsize=14)
plt.ylabel('y',fontsize=14)
plt.title('ToA heatmap',fontsize=17)
plt.show()
给予：
