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.

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)).

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

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.

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.)

Need the ability to group related bars on UI Chart.  We are not able to accomplish this using spacing and gaps currently.  We have multiple series of data but some of the series of data is related and there is no way to put the bars closer together to show the relationship without bunching all bars for a given interval together.

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.

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.  

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.

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.

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.

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). 

I would like to set dashtype, line color, line width and other line segment properties for individual line segments (between two points) of a line type series in kendo chart.

this functionality is available in Microsoft charts.

note, I can set the dashtype for the entire line no problem. I have a requirement to change the dashtype for different sections of the line. maybe starting dashed, then long dash, then solid to indicate different aspects of the data being charted.

it would be great to be able to use a function to return dashtype, line color, line width and other line segment properties based on a e.dataitem.?

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.

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.

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 

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

In the current version the legends for charts containing groups and series has a flat list of the series for each group. This is unreadable and toggling is not of any use.

The suggested improvement is a legend containing groups (e.g.) sex and series (e.g. age 0-19, 29-39 etc). Toggling of groups should be provided. Toggling of series would also be useful, but less important than toggling groups.

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

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