Hello, found the code below which is used to plot a custom grid. I'm
not 
too crazy about the dotted grid and would like to plot a solid
line, possibly 
using GFX... has anyone done that? Thanks
gridINCR = 
Param("incr",.50,1,10,0.0001);
if( ParamToggle("show custom 
grid", "NO|YES", 1) 
)
{
SetChartOptions(1,chartShowArrows|chartShowDates, 
0);
firstbarvisible = BarIndex()==1 OR (Status("barvisible") AND 
NOT Ref(
Status("barvisible"), -1));
GridMIN = LastValue( 
LowestSince( firstbarvisible, round((Low
-40)/10)*10 ) );
GridMAX = 
LastValue( HighestSince( firstbarvisible, round((High
+40)/10)*10 ) 
);
steps = (GridMAX - GridMIN)/ gridINCR ;
for(i=0;i < 
steps;i++)
PlotGrid(GridMIN+i*gridINCR, 
colorBlack);
}
else
SetChartOptions(1,chartShowArrows|chartShowDates);
