A simple black and white Line chart with Trace2- defaults have been changed though so there is some configuration required.
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: [4,5,5,6,6,7,4,5,6,8,8,9,15,16,24,25, null, null],
options: {
numxticks: 0,
numyticks: 0,
backgroundGrid: false,
colors: ['black'],
linewidth: 5,
hmargin: 5,
ylabels: false,
shadow: false,
tickmarks: null
}
}).trace2();
</script>
