Turn On and Off Plot

[velocity]

I am trying to turn on and off a plot by using a true/false statement. This is what I have:

#region Variables

private bool showplot = true;
private Color defaultColor = Color.Transparent; // to make line Blank initially but is overridden by showplot = true which sets it to Red.

protected override void Initialize()
{

if (showplot)
{
defaultColor = Color.Red; // to turn on line with Red Color
}
else
{
defaultColor = Color.Transparent; // to turn off line with Transparency
}

Add(new Plot(new Pen(defaultColor, 3), PlotStyle.Line, "MyPlot"));

When I compile there are no errors, so where am I going wrong?
When I load the indicator the plot lines come on as Red which tells me the first part of the "If" statement is working ok.
When I change showplot to False, the red lines should be gone by turning Transparent, but nothing happens and the Red lines stay on the chart.

What am I missing here?

Thanks

The Initialize function is called only once per Strategy instance (at load time)...so I think the problem is, you can't dynamically toggle inside of Initialize.

Right now, your code will just set it to Red, and never change, since Initialize will never be called again.

You would want to toggle inside of OnBarUpdate or some other spot that is frequently called to give you the dynamic toggling that you are after.

Hope that helps

I figured it out as follows

protected override void OnBarUpdate()
{

if (showplot)
{
Plots[0].Pen = new Pen(Color.Red);
}
else
{
Plots[0].Pen = new Pen(Color.Transparent); // to turn off line with Transparency
}


Thanks for taking a look.
