I see horizontal artifacts when using gnuplot to plot a sawtooth curve from binary data (unsigned short). I've attached the binary file and I used these command parameters - plot "c:\\temp\\Test_Fri09_15_11_40_A.bin" binary array=(-1) format="%ushort" with lines

Is it a bug? Is there a work-around?

Hmm... doesn't look like that data file can actually be the one corresponding to that plot you show. It's too short by about a factor of 20, and covers a much smaller range of values than your plot. Nor does it exhibit any of the artifacts.

Oh, and even the file name is wrong...

Apologies. Uploaded correct file. Artifacts don't always appear. Sometimes they show up after clicking replot.
