Is there any way to save chart values?
-
Hi everyone. I have a real time chart application.
I want to save chart values as a binary file, after that i want to upload it in a graph and see the result.
My mind is so confused. There are at least 20 different datas.
If i save them in a binary format with QDataStream, how do i know which data is which when restoring?
Im open to any idea for it, thanks for your help. -

The order is specified by your data types and in which order you write them into the stream...
