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!

Description: When 'shared' tooltip is enabled (tooltip: {shared: true}) keyboard navigation through chart triggers JavaScript error and tooltip on focus is not shown, neither shared nor regular tooltip. It works without issues when 'shared' is disabled, but when it is enabled errors are triggered.

Steps to reproduce: 

1. Open Dojo example https://dojo.telerik.com/@oleksii.shumakov@thomsonreuters.com/UqixUyuj
2. Open browser's console (F12)
3. Run the script
4. With mouse click on "India" legend item once -> India line is disabled
5. Click on "India" legend item once more -> India line is enabled
6. Using keyboard hit Shift+Tab -> Browser's console shows error: "Uncaught TypeError: Cannot read properties of undefined (reading 'format')"
7. Using keyboard hit Tab -> Dot on chart line becomes highlighted but no tooltip is shown

Stack trace of the issue:

kendo.all.js:290271 Uncaught TypeError: Cannot read properties of undefined (reading 'format')
    at init.show (kendo.all.js:290271:1)
    at init._displayTooltip (kendo.all.js:302830:1)

_keydown @ kendo.all.js:302540

Versions of KendoUI with the issue: 2024.2.514, 2024.3.806

Feature request

Introduce a regression line in the Kendo UI Chart that should be automatically calculated and included in the chart. 

Current behavior

Explicitly calculate the values for the regression line based on the values from the main series and create a new series in the chart. 

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.

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

As per http://www.kendoui.com/forums/dataviz/chart/scatter-chart-with-different-point-colors.aspx  your ScatterLine really needs the ability to set the color of the lines between the points.  It seems like an oversight that just needs to be fixed.

I want Tooltips to have a default date format for each chart base unit, for any date, like #:category#, appearing in them. Right now I have to use a custom template script and do all kinds of clever math to figure out what the base unit is, if it's set to auto.

Also all Chart types should have access to category name in tooltip.format, using {1} or similar.

The only series.highlight option that seems to be supported by "column" charts is highlight.visible.

The other options, such as border and color should be supported.

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

Currently, Category Axis Label Rotation will only rotate around the center of the label.  When labels are long, they do not align well with the chart (e.g. column chart).  See the following forum post for more info:
http://www.telerik.com/forums/categoryaxis-label-rotation---align-with-column-chart

We would like the ability to have the values of the data points on box plots to be displayed next to each plot.  For example it would be useful to know what the high, low, median values were by having the actual numerical values displayed next to the plots on the chart.  

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.

One of the basic stock chart features for amcharts\yahoo\google charts is to recalculate a percent axis during comparisons.

http://www.amcharts.com/stock-chart/
https://www.amcharts.com/tutorials/disabling-or-enabling-value-axis-recalculation-to-percents/

The stockchart should be more of a widget that allows comparisons that automatically converts to percents during comparisons.

For example, in the amcharts you can add\remove stocks easily, and when there are two stocks to compare it automatically shifts to a percent axis. The chart itself does the calculations as they are very standard.

For us, this would also need to work in a virtual MVC scenario.

Currently, we have to do the calculations either on the client\server, insert\remove\hide\show price\percent axis and legend info etc....just to duplicate other charts that are built in with these features.

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.

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.

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.

Create another series based on of 2 series in kendo chart.

when you have series A and B and want the series C would be series A / series B
