Defining Plot Variable for Histogram

[sdauteuil]

I am trying to make a simple histogram of the difference between DmPlus and DmMinus from the DM indicator included with ninja trader.

I saved the ninjatrader DM indicator as DmHistogram.

In the NT indicator there is a line of code... double sum = DiPlus + DiMinus
This would be the value of the histogram.
Below this in the code the current plots are defined.

Following this logic it tried to create/set a plot variable "HistPlot" = sum;
attached screenshot

I get an error 'HistPlot' does not exist n current context - error code CS0103

I tried defining "HistPlot" -
under Public class.. private series<double> HistPlot;
under State.DataLoaded… HistPlot =new series<double>(this);
Neither of these worked


Any help on creating the histogram would be appreciated.

Hello sdauteuil,

Is a public Series<double> HistPlot being defined?

Can you show the Properties to show this Series<double> was defined?

(See the MACD indicator on line 107 for an example)

That is not being defined under the properties.

Would I create the same code like line 141-146 for HistPlot? see attached

Would I make a values[3] since there is already values 0,1 and 2. I am not sure exactly how the values relate to the plot.

Hello sdauteuil,

If a variable is not declared it cannot be used.

Declare this public series if you want to use this variable.

To return a 4th plot added with AddPlot():

[Browsable(false)]
[XmlIgnore()]
public Series<double> MySeriesName
{ get { return Values[3]; } }

Thank you I was able to define the variable.

I am now getting an error with the addplot code.

I attached a screenshot and the code. I put /// in front of the line I was getting an error on so it would compile.

Hello sdauteuil,

PlotStyle.bar has bar lowercase. This needs to be uppercase. PlotStyle.Bar.

I would recommend you use your own plot name instead of trying to use NInjaTrader's internal resources (used for language translations with system indicators).

Thank you

Got it to work!
