The forum is great but missing some critical features.

Seems like lots of Chart features are yet to be implemented.  I want to use jQuery to hack positioning of elements like axis titles and replacing some rendered paths with images, but without classes the selections would be expensive and maybe imprecise.

This will help take some of the heat off Telerik while users wait for more functionality in the next release. Let us modify what we need!

The ability to show confidence intervals (80% and 95% intervals). Something like what can be done with the Percentiles plugin for Flotcharts:
  http://www.flotcharts.org/flot/examples/percentiles/index.html

Navigator works great.  Pan and Zoom work great.  But when you try both on the page zooming and panning completely mess up the data navigator.

I realize pan and zoom are new so maybe this is already in the works.

My support ticket pointing out the problem:
  http://www.telerik.com/account/support-tickets/view-ticket?threadid=1013202

Like jQuery 2.0, a version that leaves behind the older Internet Explorer 6, 7, and 8 browsers. In return it is smaller, faster, and can be used in JavaScript environments where the code needed for old-IE compatibility often causes problems of its own

The horizontal data selection for line charts works great...for the applications I need to build, I also need the same sort of selection vertically. Please consider implementing this soon...i know others have inquired about this as well.

If you have multiple axes shown on a chart it can be hard to determine which axis relates to a particular data point. 

Currently you can use color to visually tie them together (see http://demos.kendoui.com/dataviz/bar-charts/multiple-axes.html) but this isn't a great solution.

What would be nice is an option to highlight the appropriate axis when you hover over a data series point (similar to the new feature where data series is highlighted when you hover over the legend)

Hi, 
In kendo Line chart, currently the plot area can be colored using plotBands. 
In line with that is the requirement to color different ranges with different colors in the y-Axis line alone.
The line size can be made to 3 or 5 px to shown the color clearly.
This will help the user 
1. to understand the criticality of the different ranges.
2. Mostly line charts will be shown shown in reports, and will be given as printouts to the patients (in case of hospitals),  a report will have multiple line charts components, providing this feature will help the customers to reduce the cost on printer color catridges (that will be used when printing the whole plotbands for different ranges).

Thanks.

The grid and chart can be used in mobile apps and seem to work properly.  (See http://kendoui-feedback.telerik.com/forums/127393-telerik-kendo-ui-feedback/suggestions/4522456-touch-grid-for-tablets-that-has-as-many-features-a for the suggestion that they do work).

However, they don't adapt to the mobile appearance like the dedicated mobile widgets, which makes them hard to use in cross-platform mobile applications.

If there has two or more gantt chart on the screen. some of the value should be able to move by dragging from one to another rather than defining again.

While I think it is great you guys are doing support for Visual Studio where is the support for DreamWeaver? Is there anyone working on this? There is a jQuery Mobile set of tags in the "Insert" section of the IDE. It would be great if we had a set of tools for Kendo UI Web, Charting and Mobile.

Wouldn't it be nice to be able to filter a field as a property of a series? You could populate stacked and grouped column charts with a single datasource, without having to parse through it manually with js.

Allow the navigator in the chart (http://trykendoui.telerik.com/iKux) to be configured so it can be positioned to move vertically as well as horizontally, this is useful when selecting ranges on the Y-Axis.

Hi,

Kendo DataViz is getting awesome, but I always feel that some (albeit) common operations are made very complicated. I know there is some compatibility that must be assured but I some point the usage would be much better. Here are some common operations that are currently quite unintuitive:


* Reverse the order of an axis: reversing the order of an axis (so that values are on the right of the chart instead of the left), must currently be done by setting a very high "axisCrossingValue" (wtf?), as shown here: http://jsbin.com/iyiqec/1/edit?html,css,js,output

This definitely sounds like a hack and the wrong solution to the problem. A simple labelAlignment (left / right) would be far more intuitive.

* Being able to draw all points but still use baseUnitStep to "auto": let's say I have a chart with a lot of points. This means you need to use baseUnitStep to "auto". However, a bad consequence is that it now renders only the point for each step computed after baseUnitStep. This is often not the expected behaviour and, while drawing less labels, I often still want to display all the points (or more points). Currently, the super complicated way is to use the obscure "categoryAxes" property, make sure that one axis is hidden (but will be assigned the point), and other one is set to baseUnitStep auto, as shown here: http://dojo.telerik.com/@germanov/ULUGi

Maybe a simpler "valuesStep" option that would allow to override the step for values, independently of the category axis, could be introduced.

Thanks!

Kendo UI has accessibility built into it.  I do not know why you do not have it for Kendo UI Mobile.  Accessibility is still needed on mobile apps.  I know Android does not handle it will, but iPhones do using VoiceOver.

When integrating the Kendo UI Editor with other components, it would be nice if there was more visibility and control on the state and actions of the Kendo Editor.

For instance, bind 2 new callbacks/events: 
- onClose: function(event) {}
- onOpen: function(event) {}

Methods to control the Editor externally:
- editor.close()
- editor.open()

Methods to inquire on the Editor's state:
- editor.isOpen()

We are currently in the process of converting our site from using RadAjax controls into Kendo UI controls. We use a lot of drop downs (single select and multi select). While working with the Kendo UI controls, we saw that there were no multi select drop down controls available. There is a multi select control, however it uses a 'token' style and is not a control that we can use in our environment. There should be a multi select drop down control similar to the control used in RadAjax framework.

dojo: http://dojo.telerik.com/UMuRaBax/3

Steps to reproduce:

1. Run the dojo, let the comobox list load and let it select the default item ('Oulu' in this case).

2. start typing 'Madrid' in the input field of the combobox.

3. press Tab key and observe behavior.

Dear staff,

I am working extensively with Kendo UI Drawing API, specifically with drawDOM and exportPDF methods. I encountered a strange issue, which leads to the generation of corrupt PDF files.

After several attempts to analyze the problem, I found a small piece of code that allows to systematically reproduce the issue. You can find the code as attached.

Opening the example page with Chrome browser I got a corrupted PDF file, while Internet Explorer seems to generate a valid PDF file starting from the same source page.

Checking with an online PDF validator, the file generated by Chrome exploits this validation error:

    “The content stream contains an invalid operator.

      The operator has an invalid number of operands.”

I’m not skilled with PDF internals, but comparing the valid file of IE and the invalid file of Chrome, I noticed that an “infinite” value appears in the invalid PDF.

The row in the valid PDF is “1 0 0 -1 -9494.7900391 -9965.5996094 cm“, while the same row in the invalid PDF is “1 0 0 -1 Infinity Infinity cm”.

I noticed that the presence of an “Infinite” value is the common behavior whenever the corrupt PDF problem occurs.

I would like there to be a simple input field that allows a datasource to be attached. This would support update database operations to be sent as JSON to the desired URL, much like grid or gantt do.

Seems a bit of an oversite that you don't have this on, given the width and breadth of your other controls.
