Linearray needs two each X and Y points and rightfully complained when you
fed it two Y arrays.
The code editor in 4.69 catches that Arg #4 has incorrect type, but that's
also true for Arg #2.
Was there a reason why you used LineArray(x0,y0,x1,y1, 0, 1) in place of the
default LineArray(x0,y0,x1,y1)?

Subject: [amibroker] AFL help please: linearray.
Could someone please check I am using Linearray
correctly?
I want to plot a line from the buyprice indicating a
certain annualised percent gain, eg 10 % gain after
260 bars.
If I use this code
******************
Buy = Cross ( Close, EMA(C,30));
//price = ValueWhen(Buy,1);
x0 = ValueWhen(Buy,BarIndex(),1);
y0 = BuyPrice;
x1 = BarsSince(Buy) == 260;
//x1 = x0 + 260;
y1 = BuyPrice * 1.1;
Line = LineArray(x0,y0,x1,y1, 0, 1);
Plot(C,"",1,64);
Plot(EMA(C,30),"",1,1);
PlotShapes(shapeUpArrow * Buy,colorBlue,0,L,-15);
Plot(Line, "line", colorGreen,1);
*******************
I get the following error:
x1 = BarsSince(Buy) == 260;
y1 = BuyPrice * 1.1;
Line = LineArray(x0,y0,x1,y1, 0, 1);
-------------------------------------------^
Error 2.
Bad argument(s)
I think I am using the LineArray function correctly.
Is there an error in my x0,x1,y0,y1 initialising?
Regards
ChrisB
