Hi,

We often need to modify values of an existing graph (either to change values, or filter existing set). However animation is very ugly when doing this, as it starts the animation from start. It would be awesome if animation could be more configurable, and would allow to control how animation is processed when chart's data is changed.

Thanks!

I want to be able to allow showing tooltip on mouseclick, instead of showing it on hover a slice/point/bar. This should be configurable - what event should trigger a tooltip.

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.?

User want to drag the series point as well as series line(whole series line) in any direction, so the user can move the series where he want, please refer the below URL, where user can move the series point in vertical direction only, likewise the user want to drag the series point as well as series line in any direction, so he can set the threshold  limit where he want by using the custom series and analysis the chart against his threshold limit

It'd be useful to have more things built into DataViz to allow for keyboard accessibility and screenreader usage of the charts.

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.

Per http://www.telerik.com/forums/auto-rotate-category-labels:

Having the option of enabling automatic rotation of category-axis labels when they would otherwise overlay would be very useful.

If this is unfeasible, an acceptable compromise would be adding a client-side function that could be called to change the rotation of a rendered chart.

When hovering over a chart data item (e.g. circle), the jqeury "mouseleave" is activated almost immidiately - the "mouseleave" event is fired before I actually leave the circle.  This causes the tooltip to remain, the circle itself is shown as "onHover" (e.g. filled) - but the line is removed, since "mouseleave" is fired and this is where I remove the line.

here's an example based on kendoui example: http://dojo.telerik.com/eqaLO
Note the "Status" at the bottom of the chart - it is "Hover" when you start the hover and "Left" after leaving the circle (according to the event).

I believe a "seriesLeave" event could solve this.

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.

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.  

A way to show differences between the labels for example assigning color red to a negative value 

The majority of the charts right now choke heavily on large datasets.

http://dojo.telerik.com/urIne - This example shows 20,000 points on a scatterLine chart.  It takes a very long time to render this and, when panning or zooming, the redraw time is huge.  This means it is completely unsuited for any large data sets (I've found anything over ~1000 points creates a major lag for the end user).

Well basically the idea is as in the topic. Sometimes we need to show something in hh:mm:ss format on y-axis and it's not possible.

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

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.

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.

The only way to wrap text in category axis labels on charts is to introduce the new line character ('\n'). This is fine on fixed-width charts where labels are known at design-time. However, when dynamically adding series to charts and resizing within a responsive site, it is impossible to know where and when to use '\n'. Can a feature be implemented whereby labels flow within the bounds of their corresponding group in the chart?

Update your stock chart with Financial indicators, like SMA, EMA, VWAP and many more. These indicators are useful in trading analysis.

Have the possibility to use a specific dashType when the graph is set to "interpolate" for the missing values (null values)
