Hello,
I noticed in some of my charts that when I call saveAsPDF, the series.name seems to be just a literal string of the series.name option, even when I use a template.
Please see the attached dojo to reproduce (I based this dojo off of the Chart API series.name as template dojo example).
https://dojo.telerik.com/ZgsUVIjM
I noticed that this behavior starts in 2024.4.1112. Prior versions evaluated the template for the PDF.
I do have a workaround for this, which is included in comments in my dojo. I just exportPDF and then use kendo.saveAs.
Additionally, I noticed that the bars in the chart are at 0 in the PDF. I'm not worrying about that at this time, I'm exclusively interested in the series.name template being evaluated on saveAsPDF.
Here are some screenshots of the dojo and resulting pdf for v2024.4.1112:
Here is a screenshot of the pdf when the same dojo is run on 2024.3.1015:
Please let me know if you'd rather I paste the dojo code directly into this ticket, or attach as a code file.
Thanks!

Hi!
I am loading Kendo-UI via npm (@progress/kendo.ui:2025.4.1321). The @progress/kendo-ui package internally references @progress/kendo-charts^2.9.0. At the time I installed kendo-ui, the latest available version of @progress/kendo-charts was 2.11.0, which is why npm chose this one.
However, this version leads to a JS error when rendering bar charts similar to this one:
Error: <g> attribute transform: Expected number, "matrix(NaN,NaN,NaN,NaN,…".This is caused by line 374 in @progress/kendo-charts/dist/es/chart/chart.js (version 2.11.0). It has been added in version 2.10.0. If I am using version 2.9.0 instead (which is also served by the CDN for Kendo-UI 2025.4.1321), everything works fine.
Is there an issue in the supported version ranges of the dependencies of @progress/kendo-ui?
Or does @progress/kendo-charts not follow the rules of semantic versioning?
I would like to avoid pinning the versions of all sub-dependencies of Kendo-UI just to avoid running into such conflicts when running "npm update".
