<h1>A basic Line chart with dollar syntax example</h1>
<!-- 2/3. This is the canvas that the graph is drawn on -->
<canvas id="cvs" width="1000" height="250">[No canvas support]</canvas>
<!--
3/3. This creates and displays the graph. As it is here, you can call this from the window.onload event,
allowing you to put it in your pages header.
-->
<script>
window.onload = function ()
{
var line = new RGraph.Line({
id: 'cvs',
data: [4,8,3,4,6,9,5],
options: {
textAccessible: true,
labels: ['Pete','Lou','Pob','Luis','Barney','Fred','Wilma']
}
}).draw()
line.$2.onclick = function (e, shape)
{
alert('The third point has been clicked');
}
line.$2.onmousemove = function (e, shape)
{
return true;
}
};
</script>
<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.line.js"></script>
</pre>
Put this where you want the chart to show up:
<pre class="code">
<canvas id="cvs" width="600" height="250">
[No canvas support]
</canvas>
</pre>
This is the code that generates the chart:
<pre class="code">
<script>
window.onload = function ()
{
var line = new RGraph.Line({
id: 'cvs',
data: [4,8,3,4,6,9,5],
options: {
textAccessible: true,
labels: ['Pete','Lou','Pob','Luis','Barney','Fred','Wilma']
}
}).draw();
line.$2.onclick = function (e, shape)
{
alert('The third point has been clicked');
}
line.$2.onmousemove = function (e, shape)
{
return true;
}
};
</script>
</pre>
