Teechart series values

Hello,

Is it possible to add points to a TChart serie which its x coordinate is out of the range of the bottom axis ? And scroll the chart later to see the point ?

Thank you very much.

Why not?

This is standard situation: when you zoom in a chart part of data get
out of X-coord and become invisible but after zooming out/scrolling
data are visible again.

So you're saying that when you zoom a chart you're modifying its minimum and maximum axis values ? I thought that those axis limits were a real limitation for a serie.

It is logical to assume, I believe.

Help (v.8) states:

TChartAxis.Minimum
property Minimum: Double;

Description
Axis Minimum is the lowest value an Axis will use to scale their
dependent Series point values.

TChartAxis.Maximum
property Maximum: Double;

Description
Axis Maximum is the highest value an Axis will use to scale their
dependent Series point values.

So asis' min/max properties just set visible segment of coordinate for
series drawing.

No, AFAIK.
