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 am having problems displaying customvertical axis labels on both left and right sides. I know it can be done as I see it on the Tee8 demo. What am I missing?

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...

I would like my MACD indicator to have an horizontal solid line at Y = Zero. What is the best way to go about that? Thanks.

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 ...

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]...

Narcis, I have managed to derive a few more indicators and they work well. Multiple Moving Average, Money Flow Index, William%R etc. All derived from TeeFunction. Question? Is it possible to have two different vertical scales overlayed in TCharts. One on the Left and one on the right, each displayin...

I have now incorporated all the TChart financial indicators into my project. I now need to add several more. Multiple Moving Average Money Flow Index Average True Range Rate of Change William %R etc Would it be possible to see a Delphi example of deriving new financial indicators. For example, deriv...

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? Chart1.LeftAxis.SetMinMax(MaxMinVisibleValue(false, true, 0, Chart1.LeftAxis), MaxMinVisibleValue(true, true, 0, Chart1.LeftAxis)); And where to place it. OnAddSeries OnAfterDraw OnBeforeDrawSeries OnBeforeDrawAxes OnSc...

I have searched everywhere, through the source code, through the examples. Where is:

MinVisibleSeriesValue
MaxVisibleSeriesValue
MinVisibleValue
MaxVisibleValue

I'm trying to get my left axis to scale correctly while scrolling.
Delphi6
TChart 8 VCL

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.

Applying functions to scrollable charts. I have a financial candle chart implemented as follows. The entire data for 3000 days is stored in a Delphi type. I display 250 records at a time in Series1, a scrollable chart. However, should I apply a 21 day Moving Average TFunction, then I can only apply ...

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...
