Question on plotting bars vs lines in RMO indicator

Custom Indicators
1

I am far from a coding expert but I made an RMO indicator. I am trying to get the long term RMO (constaint D) to show as a bar or column instead of a line. Can anyone help with how I do that.

class RMO {
init() {
this.highest = MovingHigh(this.props.smoothPeriod);
this.lowest = MovingLow(this.props.smoothPeriod);
this.emaa = EMA(this.props.swingTrdLen);
this.emab = EMA(this.props.swingTrdLen);
this.ema1 = EMA(this.props.rmoLength);
this.ema2 = EMA(this.props.rmoLength);
this.ema3 = EMA(this.props.rmoLength);
this.ema4 = EMA(this.props.rmoLength);
this.sma = SMA(this.props.short);
this.sma1 = SMA(this.props.short);
this.sma2 = SMA(this.props.short);
this.sma3 = SMA(this.props.short);
this.sma4 = SMA(this.props.short);
this.sma5 = SMA(this.props.short);
this.sma6 = SMA(this.props.short);
this.sma7 = SMA(this.props.short);
this.sma8 = SMA(this.props.short);
this.sma9 = SMA(this.props.short);
}

map(d) {
	const high = d.high();
	const low = d.low();
	const close = d.close();
	const hh = this.highest(high);
	const ll = this.lowest(low);

//
const D1 = -100 * (hh - close) / (hh - ll);
const Eighty = -80;
const Twenty = -20;
const Zero = 0;

    var smav1 = this.sma(close);
    var smav2 = this.sma1(smav1);
    var smav3 = this.sma2(smav2);
    var smav4 = this.sma3(smav3);
    var smav5 = this.sma4(smav4);
    var smav6 = this.sma5(smav5);
    var smav7 = this.sma6(smav6);
    var smav8 = this.sma7(smav7);
    var smav9 = this.sma8(smav8);
    var smav10 = this.sma9(smav9);
    

    var tester = (smav1 + smav2 +smav3 + smav4 + smav5 + smav6 + smav7 + smav8 + smav9 + smav10) / 10;
    const rmoa = 100* (close - tester) / (hh - ll); 
    const rmob = this.ema1(rmoa);
    const rmoc = this.emaa (rmoa);
    const rmod = this.emab (rmoc);
    const D = rmob;
	
	return { D, rmoc, rmod, Zero};
}

filter(d) {
	return predef.filters.isNumber(d.D);
}

}
