Aquí está mi código. Necesito establecer el valor inicial como "0" en las escalas de los ejes xey. He intentado la última opción de escalas de versión.

graphOptions = {               
            ///Boolean - Whether grid lines are shown across the chart
            scaleShowGridLines: false,    
            tooltipTitleTemplate: "<%= label%>",
            //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,               
            datasetStroke: true,
            datasetStrokeWidth: 2,
            datasetFill: true,               
            legendTemplate: "<ul class=\"<%=name.toLowerCase()%>-legend\"><% for (var i=0; i<datasets.length; i++){%><li><span style=\"background-color:<%=datasets[i].strokeColor%>\"></span><%if(datasets[i].label){%><%=datasets[i].label%><%}%></li><%}%></ul>"
        };
        var LineChart = new Chart(ctx).Line(graphData, graphOptions);
   }
