[amibroker] Re: plotting x against y

["ed2000nl" <pablito@xxxxxxx>]

Graham,

I'm not sure I understand exactly what you mean. I see two lines in 
your chart where the x-axis is still plotted againt the date.

As an example what I would like to do the following code(see below). 
I calculate the array "resu". This array is plotted against the y-
axis. However I get the date against the x-axis. And actually I want 
to draw not the date against the x-axis but the array "fra". I want 
to plot "fra against resu" and I will get only one line in the chart.

regards, Ed


the code:

profit_chances = Param("profit_chances",75,0,100,0.1);
profit_perc = Param("profit_perc",2,0,100,0.1);
loss_perc = Param("loss_perc",10,0,100,0.1);

fra=BarIndex()/(BarCount-1);
resu=fra;

loss_chances = 100 - profit_chances;

for (j=0;j<BarCount;j++) {

acc=1;

	for (i=0;i<profit_chances;i++) {

		acc = acc + (acc*fra[j])*(profit_perc/100);
		i=IIf(acc < 0.01,profit_chances-1,i);

	}

	for (i=0;i<loss_chances;i++) {

		acc = acc - (acc*fra[j])*(loss_perc/100);
		i=IIf(acc < 0.01,loss_chances-1,i);

	}

resu[j]=acc;

}

resu = resu * 100 - 100;

Plot(resu,"",1,1);
