How to to show marks on mouse over

Howzit,
Is it possible to show the mark of a point on a series (Point series) only when the mouse pointer hovers over that point? Alternatively, a hint showing the text in the mark would be sufficient.

"Best Fit" Marks

Is there something like a "Best Fit" method for marks. i.e. a routine that moves the marks so that they do not overlap (esp. for a point chart where multiple points in the same position)? If not, any suggestions?

Regards,
Gilbert

A unit should not complain like that unless there is a mismatched dcu / pas file somewhere. Perhaps delphi 7.1 ships with its own chart.pas. Ensure the only copies of the files in question (dcu & pas) are those you bought from Steema. Having said this i had a similar problem when installing a non-so...

That's all cool, stream is saving properly, but - default values are not saved to stream. So, it seems, that when the chart is streamed in, values not in the stream are not set, hence my problem: Gridlines is True by default. I am streaming onto a chart where Gridlines is False and, since the proper...

I switched on Left and Bottom axis grid lines at runtime, saved the chart to stream, re-loaded the stream into another chart and gridlines where gone. How do i verify the contents of the outgoing stream - is there a way to get a te...

Then, is there a LoadChartFromStream that takes a value parameter? With the reference parameter, I have to first assign my TChart to a TCustomChart before calling the procedure.

Read-Only Series

Is it possible to make a single series Read-Only. i.e. cannot be deleted (or edited), but still allow other series' on the chart to be created and edited?

Legend Scrollbar in TeeChart 7

I have the Teechart 7 Demo (not the product). Does the legend support an horizontal scrollbar? This for legends with very long item captions.

Help Files

Just a bit confusing with the help files (under TDBChart):

"The main difference between TChart and TDBChart is that the last one NEEDS the Borland Database Engine to be correctly installed in the target machine, while TChart does not."

BDE with TDBChart

Is it necessary to have BDE installed when using TDBChart, even when using memory datasets (not BDE components)?
