Graph display problem

[Nuclamer]

I made an application (*.exe) by LabVIEW 2017. I drew the data on XY graph. The graph is step in some PC even if the original data is not step like the following picture. Same windows version, same data, same application, and different language of windows(but I think it is not language problem). Does anyone know this well?

IT IS a language problem!

One computer uses the point as decimal separator, the other uses a comma instead. (Compare the float numbers for RAM usage on both images! Chinese computer uses English numeric formatting, the other computer uses Germany regional settings.)

You can set the decimal separator in the regional settings of Windows.

You need to make your executable to be aware of the local decimal separator char…

Do the data are read form a text file? It may be the evergreen problem about the decimal separator.

In fact, if the decimal separator in the file is a point and the OS separator is a comma, values will be rounded to an integer.

Thank you for your help. You are right. Although it feels quite strange to me, I believe I will be able to resolve it thanks to you. I appreciate it.
