Re: [amibroker] Re: Looking for Gfx XY Charting template

["Tomasz Janeczko" <groups@xxxxxxxxxxxxx>]

Patrick,

No, it is not on to-do list. 
Low-level graphics uses pixels because it is natural co-ordinate system on the computer.

You can easily transform from your "values" to pixels using linear transformation:

MinY = ...your minimum y
MaxY = ...your maximum Y
MinX = ...your minimum X
MaxX = ...your maximum X

function GetPixelY( value )
{
 global MinY;
 global MaxY;

 return Status("pxheight") * ( value - MinY ) / (MaxY - MinY);
}


function GetPixelX( value )
{
 global MinX;
 global MaxX;

 return Status("pxwidth") * ( value - MinX ) / (MaxX - MinX);
}
