  • in reply to: Removing doughnut label from chart populated from a CSV #14120

    Hi Vishwas,

    Thanks for your reply. I solved it by adding:

    indexLabel: "{null}",

    So all together:

    <!DOCTYPE html>
    <html>
    <head>
    <script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.js"></script>
    <script type="text/javascript">
    
    $(document).ready(function () {
    
        $.ajax({
            type: "GET",
            url: "datapointsnumber.csv",
            dataType: "text",
            success: function (data) { processData(data); }
        });
    
        function processData(allText) {
            var allLinesArray = allText.split('\n');
            if (allLinesArray.length > 0) {
                var dataPoints = [];
                for (var i = 0; i <= allLinesArray.length - 1; i++) {
    	        var rowData = allLinesArray[i].split(',');
    	        if(rowData && rowData.length > 1)
    	            dataPoints.push({ label: rowData[0], y: parseInt(rowData[1]) });
                }
                chart.options.data[0].dataPoints = dataPoints;
                chart.render();
            }
        }
    
                
        var chart = new CanvasJS.Chart("chartContainer", {
            theme: "theme2",
    		indexLabelLineColor: "white",
            data: [
            {
                type: "doughnut",
    			showInLegend: true, 
    			indexLabel: "{null}",
    			interval : 1,
                dataPoints: []
            }
            ]
        });
                
    });
    </script>
    <script type="text/javascript" src="canvasjs.min.js"></script>
    </head>
    <body>
    <div id="chartContainer" style="height: 300px; width: 100%;"></div>
    </body>
    </html>
