two indicators with same zero line

[mdtrader]

I tried to plot a zero line into the bottom part but it seemed that each indicator has it's own scale.
Is it possible to use two indicators with the same scaling and maybe add a third one as zero line?

Thanks

You can apply same scale to multiple indicators by adding those to same AxisGroup object (just create an object and add both indicators to it).

and it works... very helpfull

Hi mdtrader,
Please can you post some sample code to draw the zero line in the same scale as the Indicator

Basically, on the QuotesDelta indicator I want to draw a LOWER and UPPER line(as on a oscillator like RSI, MACD etc) and also a zero line. Maybe in the future, also create an alert when the indicator crosses above the UPPER line(or belowthe LOWER line).

TIA

Regards,

sorry for the delay... here's my solution:

Code: Select all

    protected Indicator indicator1;
    protected Indicator indicator2;
    protected Indicator zero;

    AxisGroup grpAxis;
    AxisRules rulesAxisRules;

// when within the initialize method:
        grpAxis = new AxisGroup();
        grpAxis.add(indicator1);
        grpAxis.add(indicator2);
        grpAxis.add(zero);
        
        rulesAxisRules= new AxisRules();
        rulesAxisRules.setForcedMax(250);
        rulesAxisRules.setForcedMin(-250);
        rulesAxisRules.setSymmetrical(true);
        grpAxis.setAxisRules(rulesAxisRules); 

// for the zero line within the onInterval method:
	zero.addPoint(0);
