That's what hcoles is talking about. You do want a wee bit more.
When he talks of sensor graphs I think he is talking of parameter ID's (PID). You can get this data in text or graph with just a slightly more robust scanner. I think the subject Foxwell scanner has this capability.
Here is my Actron with a page of the PID's and the graph of the vehicle engine speed PID. Forgive the IPhone pic. It will be upside down or sideways.
If you could just access the O2 sensor readings and Fuel Trims from the PID's that would be about 80% of what a back yard mechanic would need. I do need to watch a fuel trim interpretation video every once in a while to get my head wrapped around it again but that is always really helpful.
Beyond PID's is bi-directional stuff. Talking to individual components. e.g., cycle the ABS solenoid for the left rear wheel. Or, more practically, ask what position the emergency brake on/off switch is in. If it's where it should be, it can save you tearing apart the center console.
Beyond that is flashing modules with fresh software. That gets really expensive and you still have to pay the car manufacturers a fee for the updates. Best bet is to pay a higher end shop the $100 to do it for you.
This is a casual data dump. Let me find a thread I started where Fastfred, Jeff Alton and asphaltgambler responded with respect to higher end scanners and post that.
Here it be:
