我尝试过：



我试图使用Drawline（）绘图。但是由于XY值超出了屏幕区域的许多点而感到困惑。

What I have tried:

I tried to Draw using Drawline(). but confused since XY value goes beyond screen area at many points.

推荐答案

如果你打算自己画点（至少是一个有用的练习）那么你必须通过平移和缩放来正确转换输入数据（即原始点），以使它们适合输出矩形（屏幕）。

这不是一项艰巨的任务，假设 rect 是屏幕上的rectagle，你必须

• 查找最小和最大x和y值，比如 xmin，xmax，ymin，ymax。
• 对于每个点，屏幕水平坐标为

If you plan to draw yourself the points (a useful exercise, at least) then you have to properly transform the input data (that is the original points) by means of a translation and scale in order to fit them into the output rectangle (screen).
It is not a difficult task, assuming rect is the rectagle on the screen, you have to

• Find minimum and maximum x and y values, say xmin, xmax, ymin, ymax.
• for each point the screen horizontal coordinate is

xs = (x-xmin)*rect.Width/(xmax-xmin)+rect.Left

而垂直的

ys = rect.Bottom - (y-ymin)*rect.Height/(ymax-ymin);

这篇关于我有一个文件包含以下xy数据。需要帮助来使用c＃绘图的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
