RGraph: Progress bar documentation

The example file is here. 

<script>
    window.onload = function ()
    {
        var myProgress = new RGraph.Progess('myProgress', 78, 500);
    
        // Create a gradient for the progress meter
        gradient = myProgress.context.createLinearGradient(25,0,225,0);
        gradient.addColorStop(1, 'rgba(255,255,255,1)');
        gradient.addColorStop(0, 'rgba(0,255,0,1)');
    
        myProgress.Set('chart.color', gradient);
        myProgress.Draw();
    }
</script>

Available properties

You can use these properties to control how the progress bar apears.

chart.color The color of the bar. This can be a solid color, or a gradient that you create.
Default: #0c0		 chart.tickmarks Whether the tickmarks are drawn.
Default: true
chart.gutter The size of the gutter.
Default: 25		 chart.max The maximum value. You don't need to set this because it's one of the arguments to the constructor.
chart.numticks How many tick marks there are.
Default: 10		 chart.background.color The background color.
Default: #eee
chart.orientation Either horizontal (the default) or vertical determining how the progress bar is shown.
Default: horizontal		 chart.shadow Whether the progress bar has a shadow. This uses the canvas shadow API and therefore is only supported on Chrome 2, Safari 3.1 and Firefox 3.1 (and above).
Default: false

Default: 3		 chart.shadow.offsety The Y offset of the progress bar shadow.

Default: 3
chart.text.size The size of the text.
Default: 12		 chart.units.pre The units that the Y scale is measured in (these are preppend to the number).

Default: none		 chart.title The title of the progress bar.

Default: black

Default: black
