As per support ticket 806897

Telerik: "By design both seriesClick and plotAreaClick events of Kendo UI Chart  don't contain information about the clicked button or mouse coordinates. We will appreciate it if you submit this idea as a feature request at our UserVoice portal - this way the community would be able to evaluate it and if the suggestion gains popularity we will consider its implementation for future releases."

Original request:

We are using mvvm binding to your Chart events

seriesClick
plotAreaClick

both of these events I am unable to determine which mouse button caused the click.

Is is possible or should I raise a user-voice for this?

I want to run different code if the user right-clicked or if the user normal clicked on the chart.

I would also like to know the x,y pixel position of the mouse (or tap, or tap-hold) event because depending if they interact with the top of a bar chart bar or the bottom I want to run different code...

I cannot find any of this information in the event object.

When I wrap the chart in a data-role touch widget and use the touch widgets event handling I can get this information, but it would be better that the chart events make this available.

We need functionality to allow annotations to charts (e.g. free text).

We need to annotate our charts with text that is:

- not a series value or note
- not a category note
- has no relationship with the plot data
- not a title

An example is text outlining the source of the data, 

We have succeeded in annotating charts with Snap.svg.js but the annotations do not survive the imageDataUrl() function for download (or the svg() function).

Axis & series notes won't achieve what we want to do.

We need to place free text (for example) at the top-left, top-right, bottom-left or bottom-right of the SVG.  Most importantly, it would need to be incorporated in the imageDataUrl and svg methods.

At this time rendering a chart based on a large amount of data takes a while during that period:
- loading animation stops moving
- browser does not respond to any action
- worst case the bowsers long-running-script alert appears

Suggestions:
- Would it be possible (for telerik) to do the rendering of chart in a JS web worker (JS background thread)?
- and/or is it possible to cut rendering code into small pieces (common solution to avoid browser message mentioned above) using setTimeout()? 
- give user the ability to stop rendering chart (ideally show percentage of rendering progress)

Benefits:
- keep loading animation moving while chart is rendered
- letting the user decide to stop the script if it takes too long
- suppressing browser message caused by long running script

add delay parameter for the chart tooltips (like showAfter property for the kendo.ui.tooltip) so you're able to configure if you'd like to see a tooltip if you just move the mouse pointer over a chart.
Parameter should be available on all wrappers esp. MVC.

User clicking on legend currently hides/shows that series on the chart. Would be great to have a public method that does the same so we can show/hide a series programmatically. (Like the private _legendItemClick method currently does.)

It would be nice to have a customization on drawing animations of data visualization charts. For example, draw directions, speed.

Several forum posts have mentioned that the best way to customize a legend is to hide Kendo's and make our own. I would be so great if we could just customize the legend similarly to most other areas of the chart that can be customized.

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.

I want to display a table below the chart with values as in this example  - http://telerik.com/help/aspnet-ajax/chart-plot-area-data-table.html
I am wondering if Kendo/Telerik can do it? If not, I think it would be a great idea that we be able to manipulate the data in this way?

Currently long text in chart notes makes them wide which usually results in overlapping notes. It would be great if note text is wrapped at some point. For example, if icon width can be specified and the text is wrapped to fit that width.

What would be great would be to have the ability to highlight a series plot point. The scenario is this:
- A datasource that has category, value, 'some other data'.
- The chart displays category, value
- A separate table outside the chart shows 'some other data' from the data source.
- When the user clicks a particular series plot point, show the related 'some other data' to that point and highlight the point on the chart.
- Also, the reverse situation, where the user navigates the 'some other data' records outside the chart and have the relevant point on the chart highlight.
So, now, the user can see what plot point is selected and currently shown in a table outside of the chart.

I'm sort of able to do this with notes - but it is clunky and the display isn't quite right.

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.

Currently you can bind against a datasource to pull values for a series, however if you want to specify a series as well via the datasource you cannot. This is a shame since it restricts the developers ability to do full dynamic results. 

Say for example you have a video and a poll / poll result beside the video. You cannot currently pull the poll from the server dynamically you sould have to re-create the chart from scrath using data already in the form (or do some nasty javascript building to get the chart working with series data through the datasource). 

As they are, plotbands are meaningless. There should be a facility to attach a permanent label or at least a tooltip to the plotband areas.

Currently the colorField property only sets the color of markers in scatterline line charts.  It would be very useful for us if scatterline data point field could be used to set line drawing attributes like color, width and type (solid, dash)).

It is currently possible to add titles to the Chart, Category and y-Axis, however there is no option to add a title to the legend box.

It appears that label rotation on charts will rotate on the label's center point.  If you have long labels for a column chart, then a rotation of "35" would cause labels to start at the wrong spot, and it pretty much unusable in that state.  The start of the label should be directly below the chart point in this case.  Maybe there should be a way to specify the rotation point on the label...something similar to "start", "middle", "end".  In my example, if I could tell it to rotate 35 degrees from the beginning of the label, it would render correctly.

A bubble chart without nothing inside is not that helpful, if you can set an icon or image inside the bubble itself can give quickly a hint of what it is. Also it would be nice, if the same bubble value changes position, to have an animation where it grows or shrinks while moving to the next position, instead of completely redrawing the bubble.

I suggest to add some simple arithmetic for the stack values and display them as label to explain the chart in a profession way. Such as showing the total time of all usage for the meeting room. So use sum({0}, {1}) and display it on top of the bar chart.

Add ability to add an additional title (sub-title) below the chart title and style differently that title
