The drawing API marker1 object

[No canvas support]

The marker1 object allows you to add extra information to your charts in the form of markers. These markers can then give even more information in the form of tooltips or by using the event properties.


Usage example

<script>
    $(document).ready(function ()
    {
        var line = new RGraph.Line({
            id: 'cvs',
            data: [4,9,1,3,2,6,5],
            options: {
                labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
                hmargin: 5,
                tickmarks: 'endcircle',
                colors: ['black']
            }
        }).draw()

        var marker = new RGraph.Drawing.Marker1({
            id: 'cvs',
            x: line.coords[3][0],
            y: line.coords[3][1],
            radius: 21,
            text: 'Note',
            options: {
                tooltips: ['<b>Note</b><br />The marker object can be used as a trigger for showing<br /> extra information'],
                highlight: {
                    fill: 'rgba(255,0,0,0.5)'
                },
                align: 'center'
            }
        }).draw()
