In case you are using a chart with the following configuration:

$("#chart").kendoChart({
  series: [{
    type: "radarLine",
    missingValues: "gap",
    data: [1, null, null, null, 5]
  }]
});

There is no line between the last and the first data point of the series.

But when the 2nd and 4th data points are set as well, this connection is added:

$("#chart").kendoChart({
  series: [{
    type: "radarLine",
    missingValues: "gap",
    data: [1, 3, null, 3, 5]
  }]
});

Expected behaviour: As the chart displays a "circle", all data points next to each other should be connected in case they are having a value.

 

The same issue can be seen in this DOJO, where the fifth data point is not connected to the rest of the points. This only happens if "missingValues" is set to "gap".

Bug report

Setting the visibility using the toggleVisibility method in the legendItemHover event leads to legendItemHover being triggered multiple times. Thus, the legendItemLeave method is never called.

Reproduction of the problem

  1. Open the Dojo example - https://dojo.telerik.com/@NeliKondova/UVIVaBoH
  2. Hover the legend

Current behavior

If you try to move the cursor slightly the legendItemHover event is fired multiple times and the legendItemLeave event is never called.

Expected/desired behavior

The legendItemHover should be fired a single time when the mouse enters the legend and also the legendItemLeave should be fired even if the visibility of the legend is set through the toggleVisibility method.

Workaround - Check for visible/not visible series in the series._options

function onLegendItemHover(e){
        e.preventDefault();
        console.log("Hover");       
        let chart = e.sender;
        let seriesIndex = e.seriesIndex;
        
        for(let i = 0; i < chart.options.series.length; i++){
          if(i !== seriesIndex){
            let series = chart.findSeriesByIndex(i);
            if (series._options.visible) {
	            chart.findSeriesByIndex(i).toggleVisibility(false);
            }
          }
        }  
      }
      
      function onLegendItemLeave(e){
        e.preventDefault();
        let chart = e.sender;
        console.log("Leave");
        for(let i = 0; i < chart.options.series.length; i++){
          let series = chart.findSeriesByIndex(i);
          if (!series._options.visible) {
            chart.findSeriesByIndex(i).toggleVisibility(true);
          }
        }        
      }

I need that the point will be in the start of chart (like justified property behavior) and the line style of "rangeArea" type property will be "step".

In this example the point in the start and the justified property works as expected.

https://dojo.telerik.com/IZuXOyAZ 

but in the second example, when I added property: line: {style: "step"} to "rangeArea" type, the point start in the middle of labels, and justified property not working.

https://dojo.telerik.com/ILOxehAB/3 

So I need that my chart will be like the second example, but the start point of the line will be like the first example.

When using a scatter chart with a date axis any zooming with the mouse wheel will crash most if not all browsers.

At the very least current versions of chrome (97.0.4692.99), firefox (96.0.1) and edge (97.0.1072.62).

Hi,

When creating a stacked bar chart in KendoUI 2020.3.915 I noticed the following rendering error:

In case one of the categories is much higher than the other, the x-axis will start at a value other than zero.
This behavior might be desired to zoom in on the exact values.

The issue here is that the steps on the x-axis might repeat multiple times for the same x-value.
(96%, 96%, 97%, 97%, 98%, 98%...)
This increases with a bigger difference between the chart values.

I created a example and it happens even in the latest version:

https://dojo.telerik.com/AVeVuZig

When the data values ​​are all negative, if you create a line graph using kendo chart function, Autoscale on the Y axis is not applied properly. Please check if there is any possible solution.

The two attached figures are normally auto scaled, but the charts that combine the two graphs are not auotoscale normal.

Hi,

As you can see in this dojo https://dojo.telerik.com/UTuPeMUw, there is a problem with the grid lines when I set the reverse property to true and the max property to 270 (the grid lines of angles 30, 60 and 90 are hidden).

Thank you

the dashed line in the chart is showing correctly in IE 10, but when exporting to a png image with the function exportImage, the dashed line becomes a solid line. I've been told that this can be solved with kind of polyfilling, you guys should really make this work, the reason is that this works in Chrome, for the sake of your product consistency, this feature should also work in IE.

if there is a possibility to fix an issue, I think we'd better make it.

Regards

Per version "@types/kendo-ui": "2019.3.0" , typings chart label margins and padding (ChartLegendMargin, ChartLegendPadding, ChartLegendLabelsMargin, ChartCategoryAxisItemTitleMargin,... ) don't accept number values, only a dictionary with top, bottom, left and right.

Numbers are correct values for these properties, as shown on  https://docs.telerik.com/kendo-ui/api/javascript/dataviz/ui/chart/configuration/series.labels.padding
