如何将画布的 x,y 原点更改为左下角并翻转 y 坐标? [英] How to change x,y origin of canvas to bottom left and flip the y coordinates?

问题描述

我有一堆数据点，我想将它们双向绑定到画布上的点.

I have a bunch of data points that I would like to two-way bind to points on a canvas.

假设较大的 y 值的点像大多数数学图一样反映在向上的方向上.

The points assume larger y values are reflected in an upwards direction like most math graphs.

如何将画布的 x,y 原点更改为左下角并反转它对 y 坐标的解释?

How do I change the x,y origin of the canvas to the bottom left corner and reverse it's interpretation of the y coordinate?

(我想留在 XAML)
