**LINE123:**

Hi: I am working with a programmer to do a graphical display (circles). He states that MT5 cannot perform this task since the math formula that is necessary requires a Cartesian coordinate system. He states

"**I'm afraid it's not possible, chart has got non-cartesian coord. system with two independent axes representing price and time.**

**For such calculations and plots it's necessary to have a system with fixed scaling per both axes.. "**

Can the function ChartTimePriceToXY perform this? https://www.mql5.com/en/docs/chart_operations/charttimepricetoxy

Any other ideas or feedback would be appreciated!
