ChartScale.Properties.HorizontalGridlinesInterval - No Effect

[tdouglas]

Hi,

I'm trying to set the Horizontal Grid Line Interval although it doesn't have any effect. I've tried with the code below in both an indicator and a chart style but when outputting chartScale.Properties.HorizontalGridlinesInterval to the output windows it still returns 0 and has no effect on the chart. Should it have the desired effect?

Example code is below, I've also added the 4 lines within the OnRender method to the CandlStyle chart style but also has no effect.

Thanks

namespace NinjaTrader.NinjaScript.ChartStyles
{
public class GridLinesChartStyle : ChartStyle
{
protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"Enter the description for your new custom Chart style here.";
Name = "GridLinesChartStyle";
ChartStyleType = (ChartStyleType) 8;
BarWidth = 2;
}
else if (State == State.Configure)
{
}
}

public override bool IsTransparent { get { return false; } } // replace with your logic to check if entire style is transparent

public override int GetBarPaintWidth(int barWidth)
{
return 1; //replace with your bar width logic
}

public override void OnRender(ChartControl chartControl, ChartScale chartScale, ChartBars chartBars)
{
chartScale.Properties.HorizontalGridlinesIntervalT ype = HorizontalGridlinesIntervalType.Ticks;
chartScale.Properties.HorizontalGridlinesInterval = 1;
base.OnRender(chartControl, chartScale, chartBars);
Print(chartScale.Properties.HorizontalGridlinesInt erval);
}

}
}

What is the HorizontalGridlinesCalculation set to? If it's Automatic, that value would return 0. You need to set that to Fixed.

public override void OnRender(ChartControl chartControl, ChartScale chartScale, ChartBars chartBars)
{
	Print("HorizontalGridlinesCalculation: " + chartScale.Properties.HorizontalGridlinesCalculation);
	Print("HorizontalGridlinesInterval: " + chartScale.Properties.HorizontalGridlinesInterval);
	Print("HorizontalGridlinesIntervalType: " + chartScale.Properties.HorizontalGridlinesIntervalType);
	
	if (chartScale.Properties.HorizontalGridlinesCalculation != YAxisRangeType.Fixed)
		chartScale.Properties.HorizontalGridlinesCalculation = YAxisRangeType.Fixed;
	
	chartScale.Properties.HorizontalGridlinesInterval = 100;
	
}

Worked perfectly. Thanks!
