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 the aggregate function is always very powerful to every chart type, and currently it's supported to most of the charts using category (ex. area line, bar, column, bullet), it would be very nice if you add functionality behind donut pie and funnel charts to handle category aggregation with easy instead of using datasource groupage. My request is to follow this example instead of that one

Best Regards, Boyan.

Hello,

We have an issue where encoded characters (for example: ö) in the chart category field cause the label to be misaligned.

You can see this in the following dojo example here: https://dojo.telerik.com/aMEYaziy

This dojo is based on your example (https://demos.telerik.com/kendo-ui/bar-charts/index) but I've added an encoded 'ö' character to the label for Februrary.

In our application we are passing our the labels down via ajax, and defining the field in series.categoryField (as oposed to the hard-coded values in your demo and dojo), but the effect is the same.

Please let us know what the problem is and how we can resolve it.

Thank you,

George

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

Feature request

The Kendo UI ToolTip exposes the AutoHide functionality. However, this option could not be configured for the labels' tooltip of the Kendo UI Chart

Expected/desired behavior

Be able to configure the AutoHide of the chart's tooltips. When the user hovers out, the tooltip should be persisted until a mouse click is present.

Environment

* **Kendo UI version:** 2019.3.1023
* **jQuery version:** 1.12.4
* **Browser:** [all] 

Hi Team,

It would be nice to have a feature in Charts were we can drag and drop the series points especially with Line & Bar charts. This will allow the end user to interact with data visually.

Here is the example link: https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/dragdrop/resize-column

 

Thank You,

Hitendra

I would like a built in vertical scrollbar or other visual indicator on bar charts that can be panned or scrolled.

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

I would like to request the functionality to add an image into the series displayed in a Kendo UI Chart instead of it being a color. 

Please add pdf.allpages functionality in kendo-chart similar to kendo-grid:
https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/pdf.allpages

We are using 2 kendo components together: kendoChart & kendoPager:
https://dojo.telerik.com/iqOnEHUN

We need to export the entire kendo-chart so that each page in kendo-chart gets its own page in the PDF file.

Hello, I am trying to implement https://docs.telerik.com/kendo-ui/controls/charts/overview scatter chart with multiple axes. How do I specify the series-data attribute to be [columnName, elementVal] Attached is a picture of the excel table I'm trying to reproduce. 

The out of the box legend does not offer the ability to split its items and to show them as labels over the series (graphs).

 

Extract my attached zip file and look at the MSWord document which shows you where I would like to position the 2 legends.

Add some visual indication (scrollbar, arrow image, etc.)  to give a hint to the user that the panning is enabled and there are currently not visible items in the chart:

https://demos.telerik.com/kendo-ui/bar-charts/pan-and-zoom

Please provide a property that will enable the ValueAxis of Radar Chart to be visible on top of the RadarArea series.

Currently, if the RadarArea Series has the opacity property set to 1.0, it masks the ValueAxis. To make the ValueAxis visible, the RadarArea's opacity should be reduced and this in turn makes the color of RadarArea less appealing.

Please provide a feature whereby we can make the ValueAxis visible through the RadarArea series without compromising on the opacity.

It would be great if hierarchical chart types were available. Currently there's not a good way to represent hierarchical data outside of a TreeMap, but TreeMaps don't always work well (particularly for small datapoints). An ideal chart type would be the sunburst chart (nested pie/donut charts), as it can have multiple layers, hide a segment (and all children), and potentially zoom into child layers.

There are a variety of sunburst examples currently out there from other Javascript libraries:
d3 (one of many variations): https://observablehq.com/@d3/zoomable-sunburst
Highchart: https://www.highcharts.com/demo/sunburst
Syncfusion: https://www.syncfusion.com/jquery/javascript-ui-controls/sunburst-chart

Currently the shared tooltip's position gets in the way of actually seeing the current category's series, as well as hindering any attempts to click on any series behind the tooltip.

Ideally, the tooltip should form off to the side of the current category's visible/clickable elements, either dynamically based on room available, or statically based on configuration (top, bottom, left, right). 

-- Problem:  Consider a datasource where at least two date fields span a large time frame.  We can build a chart that aggregates that data by small units (categoryAxis.baseUnits) such as 'days' or 'months'.  That chart however contains many empty data points and the 'real' data is difficult to locate on the chart.  This often requires zooming in and out many times to view the data one is looking for.  However, it is still very valuable to be able to group by day or month, and to view this data in one succinct image.

-- Demo: The best way to experience this is to use the following Demo

https://dojo.telerik.com/eCILAMOB

This dojo is from the 'Date axis' chart demo on the demos.telerik.com site under Kendo UI for JQuery.  Edit the example.  There are 17 values in the datasource.  Change the year on the last value to '2019'.  All current values have dates between 2011-2012.



-- Required Chart Setup: Create a chart utilizing the following chart options

series.aggregate = 'avg'

categoryAxis.baseUnit = 'days'

dataSource with fields that contain at least one large date span



-- Suggestion

Add option to hide date aggregates chart points where no data exists within the datasource.

 

-- Image

Possibility to have half top, half bottom, half left, half right, quarter top left, quarter top right, quarter bottom left, quarter bottom right in additiont to circle and donut chart. Please add an option to be able to shape the Pie or Donut accordingly

I want the chart rendered with svg to be able to pan and zoom on a touch device.

This is different than multi-line labels which I know are supported.  Staggered labels would put the 2nd, 4th, 6th, etc. label on a line below.  

e.g.

LABEL     LABEL     LABEL     LABEL     LABEL
         LABEL     LABEL     LABEL     LABEL
