Based on the example of Line_Interpolate in TeeChart 2015 Pro VCL, there are two questions.
1. How to use TCursorTool’s Callout at runtime?
2. For Series with custom axes, the Interpolated Points and the Horizontal or Vertical InterpolateLine are mismatching (see the attached file) when using TCursorTool. How to solve the problem?

Hello,

I'm not sure to understand the problems you are suffering. Could you please arrange a simple example project we can run as-is to reproduce the problem(s) here?

Thanks in advance.

There is a horizontal or vertical line based on the selection of the RadioGroup, and this line intersects each curve at an interpolating point. The line and interpolating points move as the mouse moves.
1. Without using other tools, such as annotation, how to use TCursorTool’s own properties to show some information about the interpolating points at Top Left/Right corner?
2. The horizontal or vertical line intersects each curve at interpolating points, so this line and interpolating points coincide (overlap), but sometimes they do not (see the attached figure).

Hello,

I've modified your example to achieve both 1 and 2:
