Hello,

how to scale different size coordinates

for example,

i have 2 points in graph which is 960 and 882 (this is referance point)

I am not certain what you want.

Try this:

Scale = [920 1; 850 1] \ [960; 882]
NewValue = [920 1; 850 1] * Scale

producing:

Scale =
   1.114285714285713
 -65.142857142856428

NewValue =
   960
   882

This simply does a linear regression (of sorts) between the old value and the new value.

You changed the numbers in your Question, so just change the numbers in the ‘Scale’ calculation in my Answer:

Scale = [920 1; 850 1] \ [960; 870]
NewValue = [920 1; 850 1] * Scale

producing:

Scale =
          1.28571428571428
         -222.857142857142

NewValue =
                       960
                       870
