Hi,

As the aggregate function is always very powerful to every chart type, and currently it's supported to most of the charts using category (ex. area line, bar, column, bullet), it would be very nice if you add functionality behind donut pie and funnel charts to handle category aggregation with easy instead of using datasource groupage. My request is to follow this example instead of that one

Best Regards, Boyan.

Hello,

We have an issue where encoded characters (for example: ö) in the chart category field cause the label to be misaligned.

You can see this in the following dojo example here: https://dojo.telerik.com/aMEYaziy

This dojo is based on your example (https://demos.telerik.com/kendo-ui/bar-charts/index) but I've added an encoded 'ö' character to the label for Februrary.

In our application we are passing our the labels down via ajax, and defining the field in series.categoryField (as oposed to the hard-coded values in your demo and dojo), but the effect is the same.

Please let us know what the problem is and how we can resolve it.

Thank you,

George

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.

Hi,

As you can see in this dojo https://dojo.telerik.com/UTuPeMUw, there is a problem with the grid lines when I set the reverse property to true and the max property to 270 (the grid lines of angles 30, 60 and 90 are hidden).

Thank you

One of the basic stock chart features for amcharts\yahoo\google charts is to recalculate a percent axis during comparisons.

http://www.amcharts.com/stock-chart/
https://www.amcharts.com/tutorials/disabling-or-enabling-value-axis-recalculation-to-percents/

The stockchart should be more of a widget that allows comparisons that automatically converts to percents during comparisons.

For example, in the amcharts you can add\remove stocks easily, and when there are two stocks to compare it automatically shifts to a percent axis. The chart itself does the calculations as they are very standard.

For us, this would also need to work in a virtual MVC scenario.

Currently, we have to do the calculations either on the client\server, insert\remove\hide\show price\percent axis and legend info etc....just to duplicate other charts that are built in with these features.

Kendo Chart has setting min/max for the axis. However, when zooming and/or dragging/panning the chart, the min/max values are no longer in effect, therefore the chart ends up displaying values outside of this range. If min/max is used to specify the current axis values, then there should be another to specify the general boundaries/range of the axis.
Example: if you have a plot with XAxis min=1950 and max=2050, when zooming the XAxis and depending on the data it will eventually display 1948 and 2060; or, it will stop at 2030 even though I requested XAxis to go up to 2050.

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.

We already have click events for the plot area, axis labels, etc., but a click event for the chart title is conspicuously absent.

I have received development requests that would require this, but currently have no available workaround to allow it.

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.

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.

The bar chart should read the value for the first day or the week from the current culture set with kendo.culture.

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.

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

Add some visual indication (scrollbar, arrow image, etc.)  to give a hint to the user that the panning is enabled and there are currently not visible items in the chart:

This event is useful on mobile device to drill-down serie, while tap (click) is for showing tooltip (or viceversa)

For the following  use cases:

1.	Drag points on a line
a)	Line chart with three or more colored lines with points on them.  User can mouse over and see the value at that point.
b)	User clicks and drags a point on any of the colored lines
c)	The graph interactively shows the point moving and the line updating
d)	User releases the mouse button
e)	That line is now updated.  Mousing over the point will display the new value at that point on the line.

2.	Click and edit a point’s value
a)	Line chart with three or more colored lines with points on them.  User can mouse over and see the value at that point.
b)	User clicks on that point
c)	At the mouse point (or any other place we determine is best to put the widget), an input area appears
d)	User inputs a new value
e)	The line and point update with the new value.   Mousing over the point displays the new value





As per sales:


“These requirements are unfortunately not built in features of the Kendo Chart.
We don't offer any way for a user to "click and drags a point on any of the colored lines" nor a built-in approach to click and edit items on the chart.

Hi Team,

It would be nice to have a feature in Charts were we can drag and drop the series points especially with Line & Bar charts. This will allow the end user to interact with data visually.

Here is the example link: https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/dragdrop/resize-column

 

Thank You,

Hitendra

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
