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 ]

We are using asp mvc, but the but it is completely reproduceable with only jquery as shown in the file attached.

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).

Chart series.highlight.markers option is missing from API and TS definitions.

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] 

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

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.

-- 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.

Would like to have automatic text wrapping enabled feature as was available in obsolete charts in the HtmlChart control as well.

https://docs.telerik.com/devtools/aspnet-ajax/controls/chart/features/automatic-text-wrapping#automatic-text-wrapping

it would be good if there is a feature to export to excel the charts.

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.

I would like to be able to see each of the y-axis values plotted along, for example, each of the values of a line or stacked chart, at all times.

The bar chart I got is drawn form the values which are normalized. I have 7 bar charts which are drawn by looping a csv file and all the values are normalized. When I hover mouse on the bar, I want to see actual values not the normalized. So I need to include a variable in tooltip object of CSS part. But it is not working, please make something regarding this.

It would be very useful to have only some series of a kendo chart be stacked. For instance, to have series 1, 2, and 3 to be stacked with each other, but series 4 to not be stacked.

When I create a chart with multiple axis, if an axis has negative values and others don't, the zero is wrong positioned on the Y axis with negative values. Currently it can only be positioned manually with min and max values. It would be great a new option to do it automatically. Example: http://dojo.telerik.com/IYavE

Add an option for AxisLabelHover (similar to LegendItemHover) on the Chart.  Because labels can be long, I truncate the text that is shown on the graph.  I need to make the full text available via the hover.
