Hello
So i have a graph whose values run below 0. i want to make the least point on this graph start from zero so that the subsequent values change accordingly. say -60 is the least point.. it should be zero on the graph the -20 will be at 40 and so on. please help me out.

Let x be your data.
xnew = x-min(x) ;
Als have a loon on the function rescale.

Or (another way) to clip all negative values at zero
x = max(x, 0);
Now negative values will be set to 0 and positive values will remain unchanged.
