We've already implemented several Kendo Chart performance optimization techniques, including:

• Canvas Rendering.
• Inline Series Binding.
• Disabling Animated Transitions.
• Disabling Gradients.
• Hiding Minor Grid Lines.
• Date Grouping using Category Axis in Date Mode.

However we are still experiencing issues when using large amounts of data.

Hi team,

Please provide an animate property part of the Tooltip interface and all tooltip-related components:

https://www.telerik.com/kendo-angular-ui/components/charts/api/TooltipComponent/

https://www.telerik.com/kendo-angular-ui/components/charts/api/ValueAxisCrosshairTooltipComponent/

https://www.telerik.com/kendo-angular-ui/components/charts/api/SeriesTooltipComponent/

..etc

Currently, the tooltip animations can be disabled through the tooltipInstance.tooltip property of the Chart reference:

@ViewChild('chart') public chart: ChartComponent;
ngAfterViewInit() {
    this.chart.tooltipInstance.animate = false;
}

Hello ,

Kindly Have issue with stacked bar when try to draw two items in chart  with specified with as the below  

<kendo-chart-series>
  <kendo-chart-series-item type="bar" [stack]="{ type: '100%' }" [data]="[97]">
  </kendo-chart-series-item>
  <kendo-chart-series-item type="bar" [stack]="{ type: '100%' }" [data]="[7]">
  </kendo-chart-series-item>
</kendo-chart-series>

I would like to request a component similar to the old TreeMap widget, but with some added functionality.  It would be great if there were native functionality in the component to drill deeper into a hierarchy rather than always having to look at the top level view (i.e. clicking a sub node would "zoom in" to view it as the new root level node).

This example treemap and sunburst (implemented using d3.js) are along the lines of what I'm suggesting.

Hi,

Please provide an ability to set the axis range in the drag/zoom events.

Thanks

Please provide the Charts selection functionality for vertical category axis as well.

thank you

I want to align the Chart Plot Area on the left side (similar to the position property of the Legend component).

Currently, the same can be achieved only with the Drawing API in render event handler. Here is an example:

https://stackblitz.com/edit/angular-ucwo6p

Providing a built-in position option for alignment of the Plot Area will be an easier and intuitive appraoch. 

Thanks.

It would be great if your pan and zoom had sliders to more easily navigate a long duration chart.  

See these couple examples: https://www.amcharts.com/demos/line-chart-with-range-slider/  https://www.amcharts.com/demos/zoomable-value-axis/

Please provide a global Charts font property that allows to set the font for all Chart elements.

Thank you.

Hi,

In the current implementation of the Kendo Chart, I'm utilizing the "panable" feature to enable movement of the chart horizontally. However, after zooming, I would prefer to utilize scrollbars instead of dragging to navigate through the chart. I would like to request a feature that allows for this behavior.

Thank you for your consideration.

We have a case with a chart with values: Date-Value that only applies to working days.

Non of the current options of missingValues ("gap" | "interpolate" | "zero") suits us. Interpolate is the closest option but it pretends to have 2 additional points (Sat & Sun) between Friday and Monday while we prefer just to connect directly Friday and Monday so both label and chart-line shape showns that 4 weeks (28 days) data based chart is based on 20 points and not 28 points (20 real points and 8 interpolated points).

Can this be achived currently? If not can you extend missingValues with additonal option (eg. "ignore") to do as explained above?

Thanks,

Tomasz

Component kendo-chart-navigator has to be usable also with other chart types not only stockchart.
We think that could be really useful to move it from StockChartModule  to ChartModule and find a way to use it in a new way!

See for example:

Hi,

Please provide an option that allows forcing the chart to use whole numbers for its value axis when zooming in or out. It's not something uncommon to have charts that can't have decimals (eg. number of people).

Thank you

Currently, the Radar Chart cannot be zoomed in/out. Please, provide a zoomable property that would allow the developer to achieve this functionality.

Hi,

Can you improve the behaviour of AxisDefaultLabels content to automatically use multiple lines when labels are overlapped instead of split them manually by using the function ?

Actual :

Expected :

Thank you for your consideration.

Please see the attached screenshot. 

On the leftmost  side, the donut chart on the top has dark blue color (Oil). And i am using the same color for the bubble chart below. But the color on the bubble is not showing dark blue but lighter one. Interestingly if i mouse over on the bubble. the color turns dark blue. how can we make it show the right color(dark blue)? and only show lighter blue when mouse over?

this is my template in case you need it. 

Hi Kendo Theme,

The current behavior will re-render the Chart and the tooltip or crosshair disappear and the user will need again to hover over the series. This behavior can be observed in the following example:

https://stackblitz.com/edit/angular-dmpexe-sf8zoj?file=src%2Fapp%2Fapp.component.ts

The desired behavior would be to keep the popup open or the crosshair present when updating the data.

Thank you for your consideration.
