Question

Using KendoUI I need to replace an exiting DotNet Charting line graph with KendoUI. Is there a way to reduce the number of vertical lines in the KendoUI line graph?

The following is an Image of the chart I’m replacing and my KendoUi chart:

This is my Kendo UI script:

jQuery('#divChart').kendoChart({ 
   title: { 
        text: "Overall Score out of 100", 
        align: "left", font: "18px Arial, Verdana, sans-serif" 
   },
   seriesDefaults: { type: "line" },
   legend: { position: "bottom" }, 
   tooltip: {  visible: true,  format: "{0}%" },
   valueAxis: 
   { 
        min: 70, 
        max: 95, 
        plotBands: 
        [
             { from: 70, to: 75, color: "#EDF5FF" },
             { from: 80, to: 85, color: "#EDF5FF" },
             { from: 90, to: 95, color: "#EDF5FF" }
        ]
    },
    series: 
    [ 
         { 
              name: "Some Product", 
              color:"004990", 
              tooltip: 
              { 
                   visible: true, 
                   template: "<b>Some Product</b><br/>Current Score: #= value # " 
               }, 
               data: [88.27,89.03,89.37,89.65,90.79,90.62,89.67,89.8,89.84,88.99,88.84,88.99,88.15,88.04,87.34,86.95,86.88,86.84,87.07,86.85,86.91,87.31,87.65,87.77,88.21,88.12,88.15,88.62,88.4,88.02,87.9,88.26,88.22,88.2,88.06,88,88.47,88.43,89.09,89.01,88.74,88.98,88.91,89.19,89.61,89.8,89.99,89.48,88.91,88.57,88.74,88.84,89.41,89.46,89.81,89.74,89.75,89.77,89.29,89.52,89.34] 
        },  
        { 
             name: "Some Market Segment", 
             color:"da7633", 
             tooltip: 
             { 
                 visible: true, 
                 template: "<b>Some Market Segment</b><br/>Current Score: #= value # " 
              }, 
              data: [79.47,79.52,79.34,79.91,80.1,79.2,79.01,78.97,78.95,78.83,78.81,78.01,77.63,77.66,76.53,74.87,75.22,75.74,75.12,74.73,74.89,74.78,74.92,74.95,74.67,74.57,75.15,75.32,75.01,74.2,73.82,73.78,72.77,72.76,71.8,71.81,72.13,72.46,72.24,72.46,72.49,72.98,73.34,74.01,74.13,74.3,74.4,74.25,73.81,73.52,73.59,73.49,73.41,73.51,73.72,73.27,74.23,73.99,73.97,73.83,73.79] } ], 
               categoryAxis:
               { 
                   labels: { rotation: -45 }, 
                   categories: [,,,,,,,,,,2008,,,,,,,,,,,,2009,,,,,,,,,,,,2010,,,,,,,,,,,,2011,,,,,,,,,,,,2012,,] 
                }

});

Any help would be greatly appreciated.

Answer 1

Reducing the number of major grid lines is not possible in the current version.

The axes support skip and step options, but only for the labels:

categoryAxis: {
    labels: {
        step: 2 // Render every second label
    }
}

We plan to extend this functionality to the major grid lines and ticks soon.

In addition, a true Date axis is also in the works. It will support common scenarios, such as this out of the box.
