How to create a horizontal RSUM

How to create a horizontal RSUM

Introduction: 

An easy way to create a horizontal RSUM in the Pivot table.

Step-by-Step Guide: 

To create a Horizontal RSUM, we will use a script. But first of all, let's prepare our dashboard. Create a new dashboard based on Sample Ecommerce, add on it Months in Date as a ROWS, Age Range as Columns, and SUM as values with formula [Total Revenue].
It will look like:

[Alt text: "Screenshot of a data visualization tool showing Rows with 'Months in Date' and 'Age Range' in Columns. Values include 'SUM' and 'RSUM'. A formula, '[Total Revenue]', is highlighted in the Sample ECommerce section."]

In the next step, duplicate the SUM value and rename it RSUM.
Press 3 dots in the upper-right corner of the widget and select Edit Script.

In the new window, copy and paste the following code:

const destinationFormulaTitle = 'RSUM';

prism.rSumConfig = prism.rSumConfig || {};
prism.rSumConfig[widget.oid] = [];


widget.on('beforequery', () => {
	prism.rSumConfig[widget.oid] = [];
})


const target = {
	type: ['value']
}

debugger;

widget.transformPivot(
	target,
	(metadata, cell) => {
		const { colIndex, rowIndex, measure, type } = metadata;
		const { title } = measure;
		if (title === destinationFormulaTitle) {
			const { content } = cell;
			if (!prism.rSumConfig[widget.oid][rowIndex]) {
				prism.rSumConfig[widget.oid][rowIndex] = [];
			}
			if (type.length === 1) {			
				const { rSum, currentValue } = getValue(content, prism.rSumConfig[widget.oid][rowIndex], colIndex);
				prism.rSumConfig[widget.oid][rowIndex][colIndex] = currentValue;
				cell.content = rSum.toFixed(2);
			}
		}
	}
);

function getValue(currentValue, row, colIndex) {	
	currentValue = (!currentValue) ? 0 : parseFloat(currentValue.replaceAll(',', ''));
	let rSum = 0;
	
	for (let i=0; i < colIndex; i++) {
		if (!isNaN(row[i])) {
			rSum += row[i];
		}
	}
	
	rSum += currentValue;
	return {
		currentValue, rSum
	}
}

Conclusion: 

You can use the Horizontal and usual vertical RSUM for your Pivot for the best result for your business.
