Your silverlight Timebar is Briliant.

I suggest you implement something like that(maybe a litle less complex) in KendoUI.

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.

Hi,
What I am looking for is a "better" way of carrying out the manual calculation for label skipping:
http://www.telerik.com/forums/how-to-access-charts-(chartarea)-width-to-calculate-labels-step(x)

Preference would be similar functionality to the categoryAxis itself (autoBaseUnitSteps/baseUnitStep/maxDateGroups) but it would only affect the labelling without aggregating the data.

Assuming similar functionality to CategoryAxis using a step of "auto" the maxDateGroups should also have an "auto" setting that would adjust the max groups so that the labels never overlap.

Thanks

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.

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!

Would like to have the ability to multi-group on chart's x-axis. Sample chart as http://goo.gl/h4l4C3

Legend displays series type/style in addition to color. Currently it only supports color and displayed as a colored square. In charts with multiple series types/styles it is impossible to distinguish between the different series based on legend only.

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.

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.

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.

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

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

It would be nice if the charts supported more marker types.  Currently only circles, triangles and squares are supported.  This poses a problem when you have more than 3 series and want to show distinct markers for each series.  I suggest adding support for a cross and star.  It would also be nice to support custom marker images.

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.

Hi,

For example, if you look at this chart in 10 days zoom view, you will notice they skip the weekends, means, they are not drawing empty data points for weekends. It is normal requirements for candle charts in stock market.

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)).

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

Please see the attached image in this thread :

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).

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?
