Multiple Line Plots

[jerryvellutini]

I'm trying to develop an indicator with three line plots. I followed the steps in the Level 2 tutorial and created Plot0, Plot1 and Plot2. When I compile, I get:
"The name Plot1 does not exist in the current context."
"The name Plot2 does not exist in the current context."

[NinjaTrader_Ray]

I believe somehow you might have accidentally deleted the properties Plot1 and Plot2 inadvertently. Try replacing Plot1 and Plot2 with Values[0] and Values[1] and see if that works?

[jerryvellutini]

I'm lost. I tried to delete the file and try over again. I get:
"This file is likely referenced by other Ninja script files and these dependencies need to be removed first."

[jerryvellutini]

Ray,
You're right. I can't re Compile indicators that use Plot1. I get error CS1002 in the plot0 line

[NinjaTrader_Bertrand]

Jerry, if you post the code we can take a look - have you ended the statement offending properly with a semicolon? http://www.ninjatrader-support.com/HelpGuideV6/CS1002.html

[jerryvellutini]

How do I post it?

[NinjaTrader_Bertrand]

Open the code in the editor and then copy the relevant parts into here and then put code tags around it, the little romb icon whe you post here...

[jerryvellutini]

I can't find the ode tags. Get:

"The name Plot1 does not exist in the current context."
"The name Plot2 does not exist in the current context."

Hmm and you are sure you get this error for the code you posted? Please double click on the error at the bottom to see exactly where those offending lines were found and in which script - NinjaTrader would compile all scrips all the time, so all need to be conflict free.

[jerryvellutini]

They are in another indicator where I tried to lot straight lines:

Plot1.Set(50);
Plot2.Set(-50);

[NinjaTrader_Bertrand]

Ok, then please ensure you have defined those Plots in the properties in the related indicator code.

[jerryvellutini]

Not clear. I didn't do anything for Plot1.

Jerry, you copied in the Add Plot1 and Plot2 statement, this way the indicator wizard did not generate the needed code lines in the properties section, you would need to add here -


#region Properties
[Browsable(false)] // this line prevents the data series from being displayed in the indicator properties dialog, do not remove
[XmlIgnore()] // this line ensures that the indicator can be saved/recovered as part of a chart template, do not remove
public DataSeries Plot1
{
get { return Values[1]; }
}

#region Properties
[Browsable(false)] // this line prevents the data series from being displayed in the indicator properties dialog, do not remove
[XmlIgnore()] // this line ensures that the indicator can be saved/recovered as part of a chart template, do not remove
public DataSeries Plot2
{
get { return Values[2]; }
}

Thank You,

I don't completely understand but I learned a lot from this.

[NinjaTrader_Bertrand]

You're welcome - this should help clarify - http://www.ninjatrader-support.com/HelpGuideV6/Add.html
