Extending TCursorTool to display over Custom Axes.

I want the vertical line of the TCursorTool to also extend across my custom axes. I want the tool to be assiged to Series1, but to display over other Series on custom axes. I figure I can spend some time coding this but do you folk have a quick method I can use.

I have a problem with TAnnotations. I create them on the fly and place them on a chart and give them a click property. With MyAnnotation do OnClick := AnnotationClick; procedure Chart1.AnnotationClick(Sender: TAnnotationTool; Button: TMouseButton; Shift: TShiftState; X, Y: Integer); begin If (Button...

Creating DrawLines in code at run time

I am having no joy creating a TDrawLineTool and placing it on the chart programmatically. TrendLineTool := TDrawLineTool.Create(Chart1); TrendLineTool.ParentChart := Chart1; TrendLineTool.Series := Series1; Chart1.Tools.Add(TrendLineTool); x1 := Series1.CalcXPosValue(Read Saved Position from TInifil...

Yeray, the code you suggest will only function while the mouse is over the actual series. I require the X value as a date returned while the mouse is moving anywhere over the entire chart. I managed it thus. ValueIndex := Round(Series1.XScreenToValue(X)); Edit1.Text := Series1.Labels[ValueIndex]; I ...

Returning the X axis label when moving mouse

I'm having a problem returning the X axis label. I load up the candle chart thus. With Series1 do begin For X := 1 To NumRecs do begin AddCandle( X, Stock_Data[X].Open, Stock_Data[X].High, Stock_Data[X].Low, Stock_Data[X].CloseP); DecodeDate(Stock_Data[X].Date, tmpYear, tmpMonth, tmpDay ); Labels[X]...

Scrolling with LineSeries and CandleSeries

I set up a simple chart as per the Scrollbar demo (TChart Pro 8) All works well with series1 as TLineSeries or FastLineSeries. BUT as soon as I make Series1 a TCandleSeries, my chart data never visibily makes it to the chart. The data is still there and the axes rescale appropriately, but where is m...

Thanks for that Yeray Now how to use it. Would this be the call to the function?

MinVisibleSeriesValue
MaxVisibleSeriesValue
MinVisibleValue
MaxVisibleValue

I'm trying to get my left axis to scale correctly while scrolling.

Thanks for that Marc. I'll do a rewrite and get rid of the Delphi types, making all the Series data available to the Chart from the outset.

First (Topmost) Node not receiving mouse clicks correctly

Howdy, I have a small problem with TeeTree. I set up several nodes, either in designing mode or dynamically. It does not matter which. The problem is the very first (topmost) node. It will not always receive mouse clicks correctly. I have seen the fix in thread http://www.teechart.net/support/viewto...
