I found another way: Series1.XValues.Locate(XValue)

Is there any way to find an index of line series by XValue? Don't want to loop XValues, because it could be more then 10000 point I created a dictionary of annotations as <XValue, TAnnotationTool> now, to move all of them on zoom or scroll, I have to find out an index of each point, contains comment...

Thank you

Hello, I have to show comments near the selected points on TLine Series (data coming from database). I am using TAnnotationTool and position the annotation correctly on a graph, but after scrolling or zooming graph - all my annotations are not in sync with my points, so how can I stick them together...

There were the questions about Undo \ Redo inbuilt functionality for TChart in 2007, are you planning to implement it soon? I am using TDragPoint and other inbuilt functions, in this case SaveChartToStream and LoadChartFromStream not returning the correct TChart. Also very often if multi Series are ...

Hello, I have Series1(TLineSeries) on a graph. After I draw the line on a graph I need all the points of Series1 that have the X values between begin and end of the line moved to the line. I can replace line with another series (Series2 that will have 2 points 1 - the begining of the line, another -...

Thank you Tom - that's provided all the answers I need.

I have replaced a Delphi TreeView with a TeeTree DBTree.

Hi Narcis,

Thanks for your help. Ver8.03 fixed the problem. I tested it several times and it worked fine.
I have to say that TeeChart is a fantastic tool - its saved me so much time in developing professional looking charts.

Thanks for your reply. I'm using version 8.02 and CodeGear™ Delphi® 2007 for Win32® Version 11.0.2804.9245. CurveFit is in the Uses Clause In the TeeChart Design tool I set up the following Series:- Series1 (Fast line) Average (using series 1) Median (using series 1) High/Low (using series1) Trend (...

Hi,

I set up a Trend function at design time. When I close Delphi and then reopen again I get the message.

"Class TTrendFunction not found".

Is this a bug?

Thanks

Thanks for your reply. It will be a couple of days before I can send you an example - I'll have to make a 'cut -down' version of my software. I'm using an SQL database called NexusDB with over million coordinates. I then filter this DB to provide the XY coordinates that I want to plot. As you probab...

I found that linking a chart to a data source and then using: (* Series1.DataSource := DataTable; Series1.CheckDataSource; *) was very slow plotting points and crashed with memory allocation with around 9,000 XY points. Manually adding the XY coords was a lot faster and did not cause a memory issue....
