Example 4.
Low-level graphic positioning - shows how to align built-in
plots() with
the low-level graphics. Note that if scale changes
(pxheight changes) due
to new data or different zoom level, it needs
additional refresh to read
new scale and adjust positions properly.
Plot(C, "Price", colorBlack,
styleLine );
GfxSetOverlayMode(0);
Miny =
Status("axisminy");
Maxy = Status("axismaxy");
lvb =
Status("lastvisiblebar");
fvb = Status("firstvisiblebar");
pxwidth = Status("pxwidth");
pxheight =
Status("pxheight");
TotalBars = Lvb - fvb;
axisarea = 56;
// may need adjustment if you are using non-default
font for axis
GfxSelectSolidBrush( colorRed );
GfxSelectPen( colorRed );
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);
}
