<h1>A HProgress chart with custom title</h1>
<p>
With this chart the title is not drawn using the title property - instead it is drawn using the ondraw
custom event along with the RGraph.Text() API function.
</p>
<canvas id="cvs" width="600" height="100">[No canvas support]</canvas>
<script>
window.onload = function ()
{
var hprogress = new RGraph.HProgress({
id: 'cvs',
min: 0,
max: 100,
value: 89,
options: {
textAccessible: true
}
}).on('draw', function (obj)
{
obj.context.fillStyle = 'black';
RGraph.Text2(obj, {
font: 'Arial',
italic: true,
size: 16,
x: obj.canvas.width / 2,
y: obj.Get('gutter.top') - 5,
text: 'A custom title drawn with the ondraw event',
valign: 'bottom',
halign: 'center'
});
}).draw();
};
</script>

This goes in the documents header:
<pre class="code">
<script src="RGraph.common.core.js"></script>
<script src="RGraph.hprogress.js"></script>
</pre>
Put this where you want the chart to show up:
<pre class="code">
<canvas id="cvs" width="600" height="100">
[No canvas support]
</canvas>
</pre>
This is the code that generates the chart:
<pre class="code">
<script>
window.onload = function ()
{
var hprogress = new RGraph.HProgress({
id: 'cvs',
min: 0,
max: 100,
value: 89,
options: {
textAccessible: true
}
}).on('draw', function (obj)
{
obj.context.fillStyle = 'black';
RGraph.Text2(obj, {
font: 'Arial',
italic: true,
size: 16,
x: obj.canvas.width / 2,
y: obj.Get('gutter.top') - 5,
text: 'A custom title drawn with the ondraw event',
valign: 'bottom',
halign: 'center'
});
}).draw();
};
</script>
</pre>
