Here we have a spline Line chart with multiple datasets. The spline option simply makes the lines curvy instead of angular. There's also a shadow enabled and the vertical grid lines are disabled.
This goes in the documents header:<script src="RGraph.svg.common.core.js"></script> <script src="RGraph.svg.line.js"></script>Put this where you want the chart to show up:
<div style="width: 750px; height: 300px" id="chart-container"></div>This is the code that generates the chart:
<script> new RGraph.SVG.Line({ id: 'chart-container', data: [ [4,1,8,6,3,5,4,2,9,3,6,3], [1,9,6,3,4,6,8,5,5,5,2,8], [4,6,3,5,2,8,9,5,6,5,6,1], [4,8,6,3,5,4,2,5,1,6,9,9] ], options: { backgroundGridVlines: false, backgroundGridBorder: false, yaxis: false, marginLeft: 50, marginBottom: 50, linewidth: 5, spline: true, shadow: true, shadowOpacity: .25, title: 'A multi-line spline chart', xaxisLabels: ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'] } }).draw(); </script>
