amcharts.getNumberOfMeasures(rawData: Object)
Returns the total number of available measures in the slice.
This method can be used to create a chart with multiple series (e.g., the stacked column chart).
| Parameter/Type | Description |
|---|---|
| rawData Object | Raw data containing the measures to count (check out the structure of rawData in getData()). |
Returns a number representing the quantity of measures in the slice.
Using amcharts.getNumberOfMeasures() to create a stacked column chart:
for (let s = 0; s < pivot.amcharts.getNumberOfMeasures(rawData); s++) {
let series = chart.series.push(am5xy.ColumnSeries.new(root, {
name: pivot.amcharts.getMeasureNameByIndex(rawData, s),
xAxis: xAxis,
yAxis: yAxis,
stacked: true,
valueYField: pivot.amcharts.getMeasureNameByIndex(rawData, s),
categoryXField: pivot.amcharts.getCategoryName(rawData),
}));
series.data.setAll(data);
}
