Q. I am using Delphi 1.0 with ChartFX 2.0. I am working on a scatter chart (with lines) and I want dates on the X-axis. How should I do this? If I use the value of a DateField, it shows a large integer on the X-axis. Also, I don't want to start on date 0/00/00 - but with the first point being the first date.

A. To change the X-axis labels in a scatter chart, you have to process the OnGetLegend event - as shown in the Help file - to customise Y-axis labels (Y-axis and X-axis in a scatter chart are very alike).

Q. To simulate a regression on a scatter graph, can I, for a second series, connect a line between the points (or between the first and last points, with the rest hidden), and make the markers 0 size?

A. Yes, you can do that. Although, you don't make the markers "zero size" and you don't turn ON the CT_POINTS flag for that second series - you use CT_SHOWLINES instead.

Q. I have activated tooltips for a bar chart (which is working nicely), but sometimes they do not appear. Is there a reason for this?

A. The tooltips appear only when the chart has the focus.
