Re: CursorTool and YValues

Hi Yeray,

I was looking for a way to draw lines/marks on Series. Drawing on the canvas leaves me with manualle handling zoom/scroll redrawing etc. the Series.Marks suit my needs, with the only problem being no points for some series at some xvalues.

Re: CursorTool and YValues

Thanks, that is what I meant! This raises the next question: I want to draw markers on all series at the given xvalue, regardless if this is a seriespoint or not. Is this possible?

Re: Installing helpfiles in Delphi XE

Hello Yeray,

I installed teechart from TeeChart2011SourceCode.exe, but found no reference to help files. Then I downloaded VCL 2010 Help (zipfile from your website) and executed installHelpToRADStudioXE.bat. Still no help.

Please advise.

Re: TTeeXMLSource X-axis date value

Hello,

It seems to me your reply concerns exporting xml. My issue concerns creating chartseries from xml, where x-axis is datetime, formatted yyyymmddhhmmss.
