Are Plots the only way to get prices highlighted in the Price Scale?

[davydhnz]

Hi,

Is it possible to get this to display in the Price Scale without using a Plot?

protected override void OnStateChange()
{
if (State == State.SetDefaults)​
{

AddLine(new Stroke(new SolidColorBrush((Color)ColorConverter.ConvertFromS tring("#90FFFF00")), DashStyleHelper.Dash, 1), 250, "250");
AddLine(new Stroke(new SolidColorBrush((Color)ColorConverter.ConvertFromS tring("#FF464A55")), DashStyleHelper.Dash, 2), 100, "100");

Thanks

Hello davydhnz,

Thank you for your post.

Price markers are only generated for plots and only when the PaintPriceMarkers property is set to true. AddLine() results in a line that is added to the chart without a price marker. You will have to use a plot if you'd like a price marker to be displayed in the price scale.

Please let us know if we may be of further assistance.

NinjaTrader_Emily,

thank you for your reply. It was helpful.

Follow up question, is there a way to set plots so that they don't have to be constantly updated in OnBarUpdate?

i.e. set them once.

Something like:

protected override void OnBarUpdate()
{
if (FirstRun)
{
// Assign values to your plots
Values[0][0] = 250; // Plot250
Values[1][0] = 100; // Plot100

FirstRun = false;
}

}

except it's static.

Much appreciated,
David

Hello David,

Thank you for your reply.

Since plot values are held in a Series<double> object, you would need to assign the value continuously and not just one time. You could call them once per bar using a script that calculates On Each Tick or On Price Change by checking if IsFirstTickOfBar is true:

protected override void OnBarUpdate()
{​
if (IsFirstTickOfBar)
Values[0][0] = 250;
Values[1][0] = 100;
}

This will assign the plot's value for the current bar only on the close of each bar rather than for every time that OnBarUpdate() is called.

Please feel free to reach out with any additional questions or concerns.

One last question, famous last words

Is there a way to make plot lines transparents, but retain their set colours in the price markers in the price scale?

Thanks.

Thanks.

For that use case, the PlotStyle.PriceBox should be used. This will use the stroke color fo the price box in the price scale and will not plot any lines on the chart itself. The AddPlot() page contains a list of the available plotStyle options:
