Data points missing in the chart

I have a sieries with 7 data points. When I plot this series (ctMarker) then only 5 data points are displayed:

When I now pan with the mouse the x-axis horizontal by just one pixel, then the missing data points are displayed as well:

The series is attached. (2.4 KB)


If you are adding X, Y points you need to use ctXYMarker instead of ctMarker

TMSFNCChart1.Series[0].ChartType := ctXYMarker;


that indeed solved the problem.
Thank you so much.
