In a chart, as we point to the end-points of the line, it shows the x & y coordinates. Can't we get the coordinates at any point on the line (via code)?

推荐答案

由于您有两点，请使用 线性方程得到直线的斜率和截距.有了等式后，您就可以随时对其进行评估.

As you have two points, use the formulae of a linear equation to obtain the slope and intercept of the line. Once you have the equation, you can evaluate it at any point.
