Spreadsheet: Trendline options inaccesible

Hello
I’m a teacher and I use OnlyOffice with my students.
But I’m missing an important function in the Spreadsheet: it’s impossible to display a trend line, with its equation, in an XY graph, even though the menu exists but isn’t accessible. So I’m forced to use another suite, less interesting than OnlyOffice, just for this oversight. Wouldn’t it be possible to integrate it in future versions?
Thanks

Hello @MmeGremont
Could you please provide us with a file sample where the trend line doesn’t appear in our editor, or provide exact steps to reproduce the situation? We will look into it.

Hello, this is an exemple

Understood, we are looking into it. I will contact you shortly.

Hello @MmeGremont
Unfortunately, the trendline option is still under development, and we cannot display it in some cases. Please clarify whether the test file was created in our editor or another one. If it was created in another editor and the trendline option doesn’t work, please send us the test file so we can check it out.
