Plotting TrendLines and accessing values

[Doctor JR]

I want to plot TrendLines and be able to access TrendLine values on the Y axis. The following simplified version of my code generates the plot and TrendLine values are nicely displayed
in the Data Box.
HOWEVER, the TrendLine plotted is a zig zag rather than a straight line. I'm confident my coding format is OK as I plot several other indicators that behave perfectly. I guess there's
something different about trend lines.
Any insight, ye masters of Ninjascript?

protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Name = "Plot TrendLines;

AddPlot(new Stroke(Brushes.CornflowerBlue, 2), PlotStyle.Line, "TrendLines1");

protected override void OnBarUpdate()
{
TrendLines1[0] = TrendLines(Close, 10, 1, 25, false)[0];
}

public Series<double> TrendLines1
{ get { return Values[0]; }}

}
}

Hello Doctor JR,

Thanks for your post.

You are creating a plot called TrendLines1 and its value is being set by the current bar value of the indicator Trendlines.

As the Trendlines indicator changes its value so will the plot.

The TrendLines indicator will not determine a new swing high or swing low to create a new trendline until the "strength" number of bars have passed.

I've created a short video to walk through this as it is easier to explain visually: https://paul-ninjatrader.tinytake.co...NV8xNzk5NTg2MQ

In short, this would be the expected behavior because your indicator is showing the current value of the active trendline from the TrendLine indicator.

You are certainly correct that for this issue visual works better than written. Thanks a bunch for going an extra distance for me. I expected the plot to look like the indicator but now I understand.
Thanks again.

I find the zig zags a bit distracting, but I discovered a cure:

ShowTransparentPlotsInDataBox = true;
AddPlot(new Stroke(Brushes.Transparent, 1), PlotStyle.Line, "TrendLines1");

Now I can implement the indicator on my chart without the distracting zig zags while accessing the current TrendLine value for my strategy.

Paul,
Thanks again for your short on-point Trendline video. Very nice.
