An alternative to the other offsetX axis demos - this uses the ymax and ymin properties instead of using drawing API objects. It has the advantage of being significantly easier (and a smaller amount of code) to implement.
This goes in the documents header:<script src="RGraph.common.core.js"></script> <script src="RGraph.line.js"></script>Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="250">
[No canvas support]
</canvas>
This is the code that generates the chart:
<script>
new RGraph.Line({
id: 'cvs',
data: [ [5,1,16,8,9,6,-5], [2,4,15,1,6,15,13] ],
options: {
textAccessible: true,
ymin: -10,
ymax: 20,
linewidth: 2,
labels: ['Monday','Tuesday','Wednesday','Thursday','Friday','Saturday','Sunday'],
ylabelsCount: 3,
numyticks: 3,
backgroundGridAutofitNumhlines: 3,
gutterBottom: 35,
gutterLeft: 35,
gutterRight: 35,
shadow: false,
textSize: 14,
numxticks: 6,
numyticks: 3,
linewidth: 3,
textAccessible: true
}
}).draw();
</script>
