**BUG**
Concise problem statement: Waveform zoom works ( left click drag release) for Transient simulations, but not for AC Simulations
Steps to reproduce bug:
1. The project is https://easyeda.com/editor#id=MK2WewqI0|4DPNLJ5E0
2. Run the simulation in AC Mode from 40MHz to 40.1MHz in 401 steps. We cannot horizontal zoom on the waveform.
3. Run the simulation in Transient Mode with default settings.. We can horizontal zoom on the waveform.
