  <pre><code>graphOptions = {               
              ///Boolean - Whether grid lines are shown across the chart
              scaleShowGridLines: false,    
              tooltipTitleTemplate: "&lt;%= label%&gt;",
              //String - Colour of the grid lines
              scaleGridLineColor: "rgba(0,0,0,.05)",
              //Number - Width of the grid lines
              scaleGridLineWidth: 1,
              //Boolean - Whether to show horizontal lines (except X axis)
              scaleShowHorizontalLines: true,
              //Boolean - Whether to show vertical lines (except Y axis)
              scaleShowVerticalLines: true,
              //Boolean - Whether the line is curved between points
              bezierCurve: true,
              //Number - Tension of the bezier curve between points
              bezierCurveTension: 0.4,
              //Boolean - Whether to show a dot for each point
              pointDot: true,
              //Number - Radius of each point dot in pixels
              pointDotRadius: 4,
              //Number - Pixel width of point dot stroke
              pointDotStrokeWidth: 1,               
              pointHitDetectionRadius: 20,

          };
          var LineChart = new Chart(ctx).Line(graphData, graphOptions);
     }
