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.
The Kendo UI ToolTip exposes the AutoHide functionality. However, this option could not be configured for the labels' tooltip of the Kendo UI Chart
Be able to configure the AutoHide of the chart's tooltips. When the user hovers out, the tooltip should be persisted until a mouse click is present.
* **Kendo UI version:** 2019.3.1023
* **jQuery version:** 1.12.4
* **Browser:** [all]
Introduce a regression line in the Kendo UI Chart that should be automatically calculated and included in the chart.
Explicitly calculate the values for the regression line based on the values from the main series and create a new series in the chart.
Pie chart labels are not properly rendered when exported to image.
The issue can be reproduced here:
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. https://mbshighway.com/features/interactive-charts
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.
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.
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.
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.
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).
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.
