I'm using Delphi XE8 with IntraWeb XIV v14.0.49 i create a TIWForm and i drooped a TChart component on it.
On the design time the TChart displayed and i can set it up.
But on the run time there is no TChart on the web page.
Is there any setting should i configure to use it ?
It seems you must use the TChart with TIWImage to display it in the webpage.
I found the following method in IntraWeb demos
// this method copies a TChart to an TIWImage
procedure CopyChartToImage(const aChart: TChart; const aImage: TIWImage);
var
xMetaFile: TMetafile;
xBitmap: TBitmap;
xRect: TRect;
begin
xBitmap := aImage.Picture.Bitmap;
xBitmap.Width := aChart.Width;
xBitmap.Height := aChart.Height;
aImage.Width := aChart.Width;
aImage.Height := aChart.Height;
xRect := Rect(0, 0, aChart.Width, aChart.Height);
aChart.BufferedDisplay := False;
xMetaFile := aChart.TeeCreateMetafile(False, xRect);
try
xBitmap.Canvas.Draw(0, 0, xMetaFile);
finally
FreeAndNil(xMetaFile);
end;
end;
