SystemHappyFace, drawShape

[philtong]

Hello all,
In the following function, I have 2 problems:
1. debug says "SystemHappyFace not defined". so i put a var SystemHappyFace stmt in the function. It stopped complaining but nothing draws.
2. nothing draws with the drawShapeRelative stmt either.
I know it's executing the function because the debugPrintln is printing all the appropriate bars.
Do I need to initialize something? or define where the images are?
Thanks in advance,
phil


function funcTrade(trade, i,bar) {
debugPrintln("[funcTrade] " + trade + ": "+i+" bar="+bar);
//drawImageRelative(xBar, yValue, Image, Url, Flags, TagName);
drawImageRelative(0, low() - vVar, SystemHappyFace, "", Image.BOTTOM, "buyShp" + getValue("time"));
drawShapeRelative(0, low() - 1, Shape.UPARROW, null, Color.green, Shape.ONTOP, getValue("rawtime") + "B");
}

correction

please use this:

function funcTrade(trade, i,bar) {
debugPrintln("[funcTrade] " + trade + ": "+i+" bar="+bar);
//drawImageRelative(xBar, yValue, Image, Url, Flags, TagName);
drawImageRelative(0, low() - 1, SystemHappyFace, "", Image.BOTTOM, "buyShp" + getValue("time"));
drawShapeRelative(0, low() - 1, Shape.UPARROW, null, Color.green, Shape.ONTOP, getValue("rawtime") + "B");
}

will help, but I suspect you need to add the TAG variable to the end of the definition, something like

bartag=bartag+1
drawImageRelative(0, low() - vVar, SystemHappyFace, "", Image.BOTTOM, "buyShp" + getValue("time"),bartag);

I believe my stmts had tags:

drawImageRelative(0, low() - 1, SystemHappyFace, "", Image.BOTTOM, "buyShp" + getValue("time"));
drawShapeRelative(0, low() - 1, Shape.UPARROW, null, Color.green, Shape.ONTOP, getValue("rawtime") + "B");

I also cut/pasted your stmt anyway, with small modifications and it also didn't draw anything.

I also cut/pased the stmt from the url and it also didn't draw anything.

BTW, I am installed into the D drive, not C: where my system folder is. I'm wondering if that is part of the problem.



final code used:

function funcTrade(trade, i,bar) {
var SystemHappyFace;
var vHL = high() - low();
var vVar = vHL * 0.25;
debugPrintln("[funcTrade] " + trade + ": "+i+" bar="+bar);

//drawImageRelative(xBar, yValue, Image, Url, Flags, TagName);
//drawImageRelative(0, low() - 1, SystemHappyFace, "", Image.BOTTOM, "buyShp" + getValue("time"));

// x, y, shape, url, color, flags, tag name
drawShapeRelative(0, low() - 1, Shape.UPARROW, null, Color.green, Shape.ONTOP, getValue("rawtime") + "B");
drawShapeRelative(0, low() - 1, Shape.DIAMOND, "", Color.blue, Shape.RELATIVETOBOTTOM, "NewDay" + getValue("time"));
drawImageRelative(0, low() - 1, SystemHappyFace, "", Image.BOTTOM, "buyShp" + getValue("time"),bar);
}

draws this

Thanks.
I took the wizard output and ran it and sure enough it works.

What I found with my code:

1. SystemHappyFace has to be in quotes
2. Shape.RELATIVETOBOTTOM changed to Shape.ONTOP worked.
3. the first one worked without change. I probably missed it.

original code:
drawShapeRelative(0, low() - 1, Shape.UPARROW, null, Color.green, Shape.ONTOP, getValue("rawtime") + "B");
drawShapeRelative(0, low() - 1, Shape.DIAMOND, "", Color.blue, Shape.RELATIVETOBOTTOM, "NewDay" + getValue("time"));
drawImageRelative(0, low() - 1, SystemHappyFace, "", Image.BOTTOM, "buyShp" + getValue("time"),bar);

Anyways, all ok. Thanks.
