When the data values ​​are all negative, if you create a line graph using kendo chart function, Autoscale on the Y axis is not applied properly. Please check if there is any possible solution.

The two attached figures are normally auto scaled, but the charts that combine the two graphs are not auotoscale normal.

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.

The only series.highlight option that seems to be supported by "column" charts is highlight.visible.

The other options, such as border and color should be supported.

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

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

The out of the box legend does not offer the ability to split its items and to show them as labels over the series (graphs).

 

Extract my attached zip file and look at the MSWord document which shows you where I would like to position the 2 legends.

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

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.

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.

As per support ticket 806897

Telerik: "By design both seriesClick and plotAreaClick events of Kendo UI Chart  don't contain information about the clicked button or mouse coordinates. We will appreciate it if you submit this idea as a feature request at our UserVoice portal - this way the community would be able to evaluate it and if the suggestion gains popularity we will consider its implementation for future releases."

Original request:

We are using mvvm binding to your Chart events

seriesClick
plotAreaClick

both of these events I am unable to determine which mouse button caused the click.

Is is possible or should I raise a user-voice for this?

I want to run different code if the user right-clicked or if the user normal clicked on the chart.

I would also like to know the x,y pixel position of the mouse (or tap, or tap-hold) event because depending if they interact with the top of a bar chart bar or the bottom I want to run different code...

I cannot find any of this information in the event object.

When I wrap the chart in a data-role touch widget and use the touch widgets event handling I can get this information, but it would be better that the chart events make this available.

-- Problem:  Consider a datasource where at least two date fields span a large time frame.  We can build a chart that aggregates that data by small units (categoryAxis.baseUnits) such as 'days' or 'months'.  That chart however contains many empty data points and the 'real' data is difficult to locate on the chart.  This often requires zooming in and out many times to view the data one is looking for.  However, it is still very valuable to be able to group by day or month, and to view this data in one succinct image.

-- Demo: The best way to experience this is to use the following Demo

https://dojo.telerik.com/eCILAMOB

This dojo is from the 'Date axis' chart demo on the demos.telerik.com site under Kendo UI for JQuery.  Edit the example.  There are 17 values in the datasource.  Change the year on the last value to '2019'.  All current values have dates between 2011-2012.



-- Required Chart Setup: Create a chart utilizing the following chart options

series.aggregate = 'avg'

categoryAxis.baseUnit = 'days'

dataSource with fields that contain at least one large date span



-- Suggestion

Add option to hide date aggregates chart points where no data exists within the datasource.

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.

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:

It would be nice be able to have a "broken" value axis on charts. Particularly bar charts, but it may apply to others.

Something to this effect: http://peltiertech.com/images/2011-11/Ybroken.png

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).
