I'm unable to infer from that screenshot what is surprising to you.

Why do you think that there is nothing unusual?

Dots mode is ok.

EV:
There are too few sample points for Sin(x)/X interpolation.

Hi All
  To Help show how DS2000 makes vectors out of sample points. I have constructed waveform files that have a low number of sample points. The sample points are calculated perfect sin values. I have chosen repeating patterns. I show 6, 4 and 2.5  sample points per cycle and at 1GSa/s.  You can see how the DSO interpolates the sin in the vector displays

These are stopped displays,  In run mode the varying trigger scanning causes the sampling to collect a series of sample along the sin display and if not a sin wave(step function) the DSO will create a sin wave overshoot.

Note : At 2.5 samples/ cycle the frequency will be accurate but Vpp is NOT.
   AS EV says very few points
