SVG Waterfall charts API reference

 

Example

The code below produces a chart like this:

<script>
    var data = [59,15,-50,-4,-8,null,15,-4];
    
    new RGraph.SVG.Waterfall({
        id: 'chart-container',
        data: data,
        options: {
            xaxisLabels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Weekday total','Saturday','Sunday','Total'],
            xaxisColor: 'gray',
            yaxis: false,
            labelsAbove: true,
            labelsAboveUnitsPost: '%',
            labelsAboveLastBold: true,
            tooltips: ['Monday','Tuesday','Wednesday','Thursday','Friday','Weekday total','Saturday','Sunday','Total'],
            colors: [
                'Gradient(black:#ddd)',
                'Gradient(red:#d00)',
                'Gradient(blue:#00d)'],
            backgroundGridVlines: false,
            backgroundGridBorder: false,
            yaxisScaleMax: 100,
            marginInner: 10,
            labelsAboveSize: 16
        }
    }).draw();

    RGraph.SVG.tooltips.style.backgroundColor = 'black';
    RGraph.SVG.tooltips.style.color           = 'white';
    RGraph.SVG.tooltips.style.fontWeight      = 'bold';
</script>

 

The coordinates properties

The coordinates of the bars on the Waterfall chart are held in the obj.coords array. Each element in the array is an object that consists of these properties:

So you could, for example, use this to get the width of the first bar on the chart:

obj.coords[0].width

Methods

 

obj.set(name, value)

This can be used to set properties if necessary. It's normally used after the chart is drawn if you need to set additional parameters or change them.

obj.on(event, handler)

This function adds an event listener (such as beforedraw or draw) to the chart object.

 

obj.exec(func)
