Rectangular zoom
Hi,
I have to implement rectangular zoom on charts. I am using VCL C++. Is there any algorithm to implement rectangular zoom ? I am not able to calculate the relation between position of Horizontal (or Vertical) Scrollbar and zoomed data.
Please share with me some ideas to implement rectangular zoom.
Thanks,
