}
var bar = new RGraph.Bar({
id: 'cvs',
data: [12,13,16,15,16,19,19,12,23,16,13,24],
options: {
textAccessible: true,
eventsMousemove: myMousemove,
eventsClick: myClick,
labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
}
}).draw();
};
</script>
<p>
This is a basic example of the Bar chart that shows you how to use the pseudo-events that RGraph has:
</p>
<ul>
<li>events.click</li>
<li>events.mousemove</li>
</ul>
<p>
Here the mousemove event is used to change the mouse cursor (it's automatically changed back for you). And the click event
is used to show an alert.
</p>
<p></p>
This goes in the documents header:
<pre class="code">
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.bar.js"></script>
</pre>
Put this where you want the chart to show up:
<pre class="code">
<canvas id="cvs" width="1000" height="250">
[No canvas support]
</canvas>
</pre>
This is the code that generates the chart:
<pre class="code">
<script>
window.onload = function ()
{
<span>/**
* This is the function for the mousemove event. It changes the pointer to the hand.
* When the mouse is moved away from the bar the pointer is changed back to what it was
* automatically for you.
*
* @param object e The event object
* @param array bar The details of the bar thats was mouseover'ed
*/</span>
function myMousemove (e, bar)
{
return true;
}
<span>/**
* This is the function for the click event.
*
* @param object e The event object
* @param array bar The details of the bar thats was clicked
*/</span>
function myClick (e, bar)
{
alert('A bar was clicked');
}
var bar = new RGraph.Bar({
id: 'cvs',
data: [12,13,16,15,16,19,19,12,23,16,13,24],
options: {
textAccessible: true,
eventsMousemove: myMousemove,
eventsClick: myClick,
labels: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
}
}).draw();
};
</script>
