Hello wiring people
Is there an easy way to find out how many records there are in a datalog
file?
I've thaught about reading every record sequentially till an error
occurs (or "offset after read" == "filesize") but I think that's not
really economical. Is there a better way to do this?

Ok, i could solve it by stacking 3 Graphs over each other and making the
upper two transparent... It's really bad to handle when i want to change
some propertys on the graphs, but thanx to the property-nodes they get
