Plotting text at a fixed corner of the screen MULTICHARTS

July 21st, 2019, 02:44 PM

I am trying to put together text that displays on my screen and lets me know what's going on at a moments notice. However, so far the best I could do is get it to fix a certain distance from the current bar. The end result is that the text bounces around as the bar develops.

Is there sample code or suggestions as to how I can display text in the top right corner of the screen no matter what is going on with the chart???

Thanks

Sinatra Fan,

you can use the reserved words aiHighestDispValue and aiLowestDispValue to get the current highest and lowest values of your screen. Together with aiLeftDispDateTime and aiRightDispDateTime you can update the location of the text to what ever your screen currently shows.
It might make sense to use a timer to forcefully update the location change in the absence of incoming ticks.

You can also use the chartinghost object. It's very difficult but is explained pretty well if you search for a youtube video on Drawing Text Objects In A Static Position.

The code for the video example:

Code

Using elsystem; 
Using elsystem.drawingobjects; 
Using charting; 

Var: 
TextLabel Text1( Null ), 
TextLabel Text2( Null ), 
ChartingHost ChartingHost1( NULL ); 


method void ChartingHost1_OnSize( elsystem.Object sender, charting.OnSizeEventArgs args )
Vars: XYPoint XYPt; 
begin 
XYPt = XYPoint.Create( args.Width - 100, args.Height * .9 ) ; 
Text1.PointValue = XYPt; 

XYPt = XYPoint.Create( args.Width - 100, args.Height * .85 ); 
Text2.PointValue = XYPt; 
end; 

method void ChartingHost1_OnInitialUpdate( elsystem.Object sender, charting.OnInitialUpdateEventArgs args ) 
Vars: XYPoint XYPt;
begin 
XYPt = XYPoint.Create( args.Width - 100, args.Height *.9 ); 
Text1.PointValue = XYPt; 
XYPt = XYPoint.Create( args.Width - 100, args.Height *.85 ); 
Text2.PointValue = XYPt; 
end; 

Once 
Begin 
 
ChartingHost1 = new charting.ChartingHost; 
ChartingHost1.Name = "ChartingHost1" ;
ChartingHost1.oninitialupdate += ChartingHost1_OnInitialUpdate; 
ChartingHost1.onsize += ChartingHost1_OnSize;
 
Text1 = TextLabel.Create( XYPoint.Create( 20, 20), NumToStr( XAverage( C, 30 ), 5 ) );
Text2 = TextLabel.Create( XYPoint.Create( 20, 20), NumToStr( XAverage( C, 10 ), 5 ) ); 

Text1.Persist = true; 
Text2.Persist = true; 

DrawingObjects.Add( Text1 ); 
DrawingObjects.Add( Text2 ); 

End;

Text1.TextString = NumToStr (XAverage(C,30), 5);
Text2.TextString = NumToStr (XAverage(C,10), 5);
