Hi expert：
We found that there was only one peak in the x-y scatter plot of the level sensing project, which is supposed to be 3 peaks as illustrated as the document in that project. 
Our setup is:
1. AoP 6843
2. Corresponding firmware (68xx)
3. The default configuration file (0.3~3m)
4. ITB 4.10
5. Visualizer launched from the document
The question is where we can find the visualizer (with 3 peaks as seen as in the doc)?
