Is there any way to not show the data point mark on the waveforms?
If you zoom in enough, the individual data points will be indicated. The more you zoom in, the bigger the dots. The algorithm isn’t great, but it’s better than having to wait for a redraw if you zoom to fit a large dataset with display datapoints enabled.
OK, but isn’t there a setting to not show (turn off) the data points?
Nope, they turn on and off automatically.
