Multi-plots of the same oscillator in one panel, how?

October 28th, 2011, 02:45 PM

How do you get (or edit) an oscillator (i.e, CCI, etc.) to plot itself twice in the same panel, let's say once as a line and anther time as a histogram without applying the indicator twice? All other setting are the same. The idea is to add a boundary to the histogram.

Thanks a bunch!

If you don't want to simply add the indicator twice, and delete the duplicate plots (make them transparent), while leaving the useful plot and setting it how you want (histogram) --- then the only other option is to make a new indicator and add the Plots to the code.

Thanks Mike. I actually did try to modify, as an example, the default fisher transform indi by adding an extra add new plot statement for a second plot of the indicator, however, it plotted the end "Value" only once. Also, tried to use the Value.Set() twice and did not worked either.

Do I need to add a new data series also for the second plot?

Thanks.

Just add a second plot in Initialize() and add a property for the that plot in the Properties section. When you add a plot, the plot series is added automatically, you do not need to define a separate variable for the data series.

Set the values for the second plot in OnBarUpdate() exactly as you have set them for the first plot and the plot should display correctly.

Thanks Fat Tails. I will try that today after the Gators have whooped the Dogs, starting in few minutes

Thanks again Fat Tails. I tried your suggestion as an example for FT. It compiles fine but I can't get it to plot twice. Attached is what I have done.

(1) You have called your two plots the same name. If you have two children, would you give them the same name?

-> Give your two plots different names, for example "PlotLine" and "Histogram"

Code

            Add(new Plot(new Pen(Color.DodgerBlue, 6), PlotStyle.Bar, "PlotLine"));
            Add(new Plot(new Pen(Color.White, 2), PlotStyle.Line, "Histogram"));

(2) You have neither defined a property for the first nor for the second plot.

-> Define properties for both plots in the Properties section - I have told you so in my last post.

Code

        [Browsable(false)]
        [XmlIgnore()]
        public DataSeries PlotLine
        {
            get { return Values[0]; }
        }

        [Browsable(false)]
        [XmlIgnore()]
        public DataSeries Histogram
        {
            get { return Values[1]; }
        }

(3) You have not set any value to the second PlotSeries, but have set a value to the first PlotSeries twice.

-> Once you have defined properties you can use them for setting values.

Code

PlotLine.Set(fishValue);
Histogram.Set(fishValue);

Not tested.

Thanks a bunch Fat Tails. It worked fine.

Yes, you told me so, but I thought the properties were already defined under the add plot statement, as in the default version.

By the way, I was told Germans can't be funny, but that is no longer true.

And no, I usually call my babies "Come", and usually one of them will show up for a treat
