推荐答案

我不知道您使用什么图表库，但是这个问题可以通过……一点点思考来解决.
基本上，它可以像坐标系的简单平移一样简单(按常数值平移).或是将翻译与膨胀或缩放比例结合使用(您没有解释如何将左图转换为右图的任何细节)，这就是为什么我说也许").

http://en.wikipedia.org/wiki/Parallel_shift [ http://en.wikipedia.org/wiki/Scaling_%28geometry%29 [ ^ ]，

I have no idea what charting library do you use, but this problem is solved by… little thinking.
Basically, it can be as simple as a simple translation of coordinate system (a shift by constant value). Or maybe a combination of translation with dilation or scaling (you did not explain any detail on how you left graph should be transformed to a right one), that''s why I say "maybe").

Still need help.
The thing is that:

There is points with very little values (-2,000e-10... etc).
So when ill add there points with values (10,10), (20,20), (30,30) its look like that:

So basically i want something like that:

where i can see all previous loaded data points, and also the biggest values.
