Dear KendoReact Team,
Our Development Team considers using KendoReact UI library in the development activities our softwares.
Our team needs a third-party library for especially DataGrid, Line Chart and Gantt Chart components and We have "must have" requirements that needs to be met on these components.
As a result of the research and integration studies our team have done on KendoReact, the following requirements and performance expectation are not met by KendoReact components:
- The Gantt Chart component must allow zooming in and out the time scale with mouse or buttons. (day/week/year filter not enough)
- The Gantt Chart Component must provide tooltips on the tasks.
- In the Line Chart, we have some performance considerations. We integrated KendoReact to test its performance and the results as follows:
- 1 Chart with 1000 points : there is a delay around 4 seconds on rendering.
- 10 Chart with 1000 points: there is a delay around 40 seconds on rendering.
We also used performance optimization methods mentioned in the link but the issue is remaining. (https://www.telerik.com/forums/low-performance-rendering-in-line-chart)
For the render performance issue, not sure it’s related but in the integration phase, our team used npm packages in the below, not the trial version.
Could you please inform us about Gantt Chart features I mentioned earlier can be provided and Line Chart performance issue can be resolved?
As this matter is urgent, I would appreciate a reply as soon as possible.
Thank you.

Hi Sena,
Thank you for reaching out to us.
Regarding your first requirement, the Gantt component supports predefined views for day/week/month/year and with that in mind, zooming functionality is not available.
For the tooltips over the tasks, this is also not supported scenario, but we have an open feature request for it and you can give a vote for that feature, so it can increase its priority:
You can also create a feature request in our public portal for the zooming functionality of the Gantt.
As for the Chart performance issues, I have tested the following example with 1000 points and it is rendered instantly:
Additionally, you can enable zooming and panning (and/or the Navigator), which can further limit the number of points and allow faster rendering:

Regarding the package, the trial version and the licensed ones are the same and they do not have impact on the performance. However, as mentioned in the forum thread that you have linked, testing with a production build will have multiple times faster performance in general.
Hope this helps.

Konstantin Dikov
