Hi,
Try to understand Exemple 4 from "Using low-level graphics
functions".
And more specially this code :
for( i = 0; i <
TotalBars AND i < ( BarCount - fvb ); i++ )
{
x = 5 + i * (pxwidth
- axisarea - 10) / ( TotalBars + 1 );
y = 5 + ( C[ i + fvb ] - Miny ) * (
pxheight - 10 )/ ( Maxy - Miny );
GfxRectangle( x - 1, pxheight - y - 1, x
+ 2, pxheight - y + 2);
}
Thanks,
Pierre
