I have a graphic and i have to Remove all points which height (in the axis y) are more than 75% of the height. Actually, i don't remove this points, just move them to (x, 0.75·heightofword)

How can i do this?

Thanks very much!!!

在 MATLAB Online 中打开

Just clip the y axis to 75% of the max y value.

maxY = max(y);
maxYForGraph = 0.75 * maxY;
ylim([min(y), maxYForGraph]);

I have tried to use what you wrote me but without succes. anyway the thing that i have to do before is this:

To move the corner to (0,0).I have to find xmin and ymin and then each point (x,y) has to move to (x-xmin, y-ymin). The height of a word is ymax-ymin (before moving). If i compute it after having moved then it is ymax’ (ymax after the moving).

how i can do this?

Thanks so much!
