SpreadJS supports waterfall charts. Use the GC.Spread.Sheets.Charts.ChartType.waterfall property to get the chart type. Waterfall charts show a running total as values are added or subtracted. They are useful for understanding how an initial value (for example, net income) is affected by a series of positive and negative values.
You can add a waterfall chart to SpreadJS and change its style using the chart API:
window.onload = function () {
let spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), {
sheetCount: 2
});
initSpread(spread);
};
function initSpread(spread) {
let sheets = spread.sheets;
spread.suspendPaint();
spread.fromJSON(data);
let customWaterfallChart = sheets[0].charts.add("customWaterfallChart", GC.Spread.Sheets.Charts.ChartType.waterfall, 400, 0, 700, 450, "B2:C15");
let baseWaterfallChart = sheets[1].charts.add("baseWaterfallChart", GC.Spread.Sheets.Charts.ChartType.waterfall, 400, 0, 700, 450, "B2:C15");
setCustomStyle(customWaterfallChart);
setBaseStyle(baseWaterfallChart);
spread.resumePaint();
}
function setCustomStyle(chart) {
let chartArea = chart.chartArea();
chartArea.fontSize = 14;
chart.chartArea(chartArea);
let dataLabels = chart.dataLabels();
dataLabels.showValue = true;
dataLabels.color = 'rgb(64,60,61)';
dataLabels.position = GC.Spread.Sheets.Charts.DataLabelPosition.center;
chart.dataLabels(dataLabels);
let legend = chart.legend();
legend.position = GC.Spread.Sheets.Charts.LegendPosition.bottom;
chart.legend(legend)
let title = chart.title();
title.text = "Monthly Income";
title.fontSize = 16;
chart.title(title);
let series = chart.series().get(0);
series.showConnectorLines = true;
series.gapWidth = 0.2;
series.subtotals = [0, 13];
chart.series().set(0, series);
chart.formatOvers({
0: {
backColor: "rgb(61,198,147)",
},
1: {
backColor: "rgb(225,128,99)",
},
2: {
backColor: "rgb(91,188,214)",
}
});
}
function setBaseStyle(chart) {
let title = chart.title();
title.text = "Monthly Income";
title.fontSize = 16;
chart.title(title);
let series = chart.series().get(0);
series.showConnectorLines = true;
series.subtotals = [13];
chart.series().set(0, series);
}
