How to change chart value via Tchart Delphi 7?

Question

Delphi

Can you tell me how to build a graph in Tchart Delphi 7 using double array values? And then through the Thrart component, using the mouse to change the value of the point (you can only change the Y axis), save the changes in the Array?

Answer 1

A series is added to TChart. This is an object that describes the structure of the output curve: type, color, coordinates, etc. A series is added either by double-clicking on the component or in the code.
Further, the series has the addXY() method, with the help of which the point drift of this series.
