There should be an option to set the number of labels user want to view at any time on any axis. Currently there is nothing like that and no concrete workaround and the user can implement. 

-- 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

The bar chart should read the value for the first day or the week from the current culture set with kendo.culture.

We dynamically update our charts based off a polling period. If there was tooltip show/hide events, we could suspend polling while the tooltip is visible. Currently, we continue to poll and when the dataSource is updated, the tooltip goes away. This unfortunately leads to another problem that when that tooltip is displayed again, the displayed point no longer resides on the plot line. I'll file a defect report for that.

I use it to upload a chart, I'd like to prevent showing the uploaded chart in the browser.  Prefer to just upload and then get control back and let my app decided what to do next.

Hi Team,

I'd like to request the functionality to add positioning and alignment to the Kendo UI Chart's API for the Tooltip.

For example, I have a 100% stacked chart.  Having the tooltip aligned all the way to the right instead of being able to anchor it to the middle of the data just feels weird for our purposes. I was hoping to inquire if there was another way that I may be missing to align the tooltip nicely.

Thank you!

Hi Team,

I'd like to request the ability to display a table for the X-Axis Label of the Kendo UI Chart as a built-in configuration.

Thank you.

Feature required where user cannot increase/decrease selection range, they can only move the existing selection window.

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  

Kendo Chart has setting min/max for the axis. However, when zooming and/or dragging/panning the chart, the min/max values are no longer in effect, therefore the chart ends up displaying values outside of this range. If min/max is used to specify the current axis values, then there should be another to specify the general boundaries/range of the axis.
Example: if you have a plot with XAxis min=1950 and max=2050, when zooming the XAxis and depending on the data it will eventually display 1948 and 2060; or, it will stop at 2030 even though I requested XAxis to go up to 2050.

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

The stack bar chart is not rendered as expected when stack.type is set

Reproduction of the problem

1. Open d the Demos - https://demos.telerik.com/kendo-ui/bar-charts/stacked100-bar or the API

• https://docs.telerik.com/kendo-ui/api/javascript/dataviz/ui/chart/configuration/series.stack#seriesstacktype
• https://docs.telerik.com/kendo-ui/api/javascript/dataviz/ui/chart/configuration/seriesdefaults.stack.type

Current behavior

The Chart is not rendered correctly, the bars are misaligned.

Expected/desired behavior

The bars should be aligned.

Regression: The issue is reproducible starting with 2024.1.130 version

Environment

• Kendo UI version: 2024.1.130
• Browser: [all ]

Current Label Position, Padding & Rotaton helps to adjust the label. Am  looking to get implement a approch where each slice/Wedge represent with a unique name so like to show the x axis label in the middle of the slice/wedge instead of label appearing along with the line.

The same case in Y Axis to show the label in the middle of the circle instead on the line of the circle to make it clear on the each circle represnt the entire circle.

How to achive those or any alternative for the same

Hi Team,

I would like to request the functionality to plot a chart with panes side-by-side instead of only top to bottom.  

Thank you!

Charts support keyboard navigation. Currently, the focus indicator is rendered as a thick black border around the different chart items. Is there any way to customize it? We usually use dashed red borders throughout our application to indicate focused elements and it would be great to stay consistent.

I found this article which leverages the highlight and saw that the series.highlight.toggle setting allows modifying the highlight's visual element, but options are very limited and do not allow sufficient customization.

Chart Series provide a toggleVisibility() method that allows to hide some data points of the series (or all of them) from the user. However, setting the first series to invisible breaks the chart's keyboard navigation.

This DOJO demonstrates the behavior: For the sake of simplicity, the first of the two series is toggled invisible right after the chart is rendered, but this may happen at any other point in time. Click anywhere in the DOJO's output area. Press TAB to focus the chart. The following error is logged in the browser console:

Uncaught TypeError: Cannot read properties of undefined (reading 'options')
    at init.focusVisual (kendo.all.min.js:9:4230266)
    at init._focusElement (kendo.all.min.js:9:4410242)

Hi Team,

I would like to see a no-data-template be included for the Kendo UI Chart when there is no data.

Thank you!

Currently each of the labels for the:

• Axises
• Legend
• Tooltip
• Chart Title

Provide their own "font" property setting. However, it would be beneficial if there is a default configuration that can apply a font for each of the aforementioned Chart Label compartments.

Hi Team,

I would like to request the Kendo UI Chart to be able to use the defined culture for localization.  Currently in my application, the date is showing as English formatting(1/30) instead of German(30.1) unless I specify the categoryAxis.labels.dateFormats configuration as seen in this Dojo.

Maybe include a culture property like the theme property?

Thank you for the consideration!

Hi Team,

I'd like to request the CategoryAxis.Justified property be supported for other series types of the Kendo UI Chart.  In my case, this would be beneficial since I have a combination of a line and box plot Kendo UI Chart.

Thank you!
