Formatting the Y-Axis

January 16th, 2011, 03:25 PM

I am currently trying to format the y-axis of the indicator panel of a NinjaTrader chart and have not found a solution. Here comes the first of my current problems:

(1) Indicator that displays the NOB spread. The NOB spread shall be displayed in '32 similar to the bond quotes.

The price marker can be correctly formatted by overriding FormatPriceMarker(), but how can I format the Y axis?

(2) I have a similar problem for the Heiken-Ashi indicator.

How can I format the Y axis for the lower panel to display pips instead of 2 decimal places?

I am unsure but is there something in chartcontrols that will control the y axis?? I am no expert I will see what i can find to help you out.

The only thing i can readily think of is to right click the right margin and adjust the properties

But the properties don't let you select the format of the legend for the axis?

if you go from auto to manual, then you could override i think. Still looking into it further

In manual mode you can fix the upper and lower margin, but I did not see any option to format the numbers.

Actually I would like to access the formatting of the indicator axis via code.

The price marker on the axis could be formatted, although this formatting currently shifts the y-axis:

However, I did not find a possibility to format the axis itself.

ChartControl.HasRightYAxis =true;

tried that but it says it is only read only

I just throw this one in here, maybe it helps or not.

I have not solved the original scale problem, but found the solution to another small NinjaTrader bug.

If you take a default bond or treasury chart, for example ZB 03-11 or ZN 03-11. and apply an indicator such as a simple EMA, you will observe

- that the price marker of the EMA does not show a correct value
- that the y-axis of the chart is shifted to the left

This can be avoided, if you add the following code to every (!) indicator, which is overlaid on panel 1 of the chart.

Code

public override string FormatPriceMarker(double price)
{
	double truncatedPart = Math.Truncate(price);
	int fractionalPart = Convert.ToInt32(320 * Math.Abs(price - truncatedPart) - 0.0001); // rounding down for ZF and ZT
	string fraction = "";
	string priceMarker = "";
	if (TickSize == 0.03125) 
	{
		fractionalPart = fractionalPart / 10;
		fraction = fractionalPart.ToString();
		if (fractionalPart < 10)
			fraction = "'0" + fraction;
		else 
			fraction = "'" + fraction;
		priceMarker = truncatedPart.ToString() + fraction;
	}
	else if (TickSize == 0.015625 || TickSize == 0.0078125)
	{
		fraction = fractionalPart.ToString();
		if (fractionalPart < 10)
			fraction = "'00" + fraction;
		if (fractionalPart < 100)
			fraction = "'0" + fraction;
		else	
			fraction = "'" + fraction;
		priceMarker = truncatedPart.ToString() + fraction;
	}
	else
		priceMarker = price.ToString(Gui.Globals.GetTickFormatString(TickSize));
	return priceMarker;
}

If have added this piece of code to the default EMA. Now the price marker is correct and the y-axis does not shift. The modified indicator is attached below.

I think that NT will address the bug in one of the next releases. We don't want to recode all indicators, do we?
