I have completed Lab2b but my screenshot # 3 is different from screenshot provided in the instructions. Please see attached the screenshot of my own work . The maximum value for average investment amount on in the screenshot provided in the instructions is 800,000 but the maximum value that I have on my graph is 700,000. Besides that the rest of the values doesn't agree as well.
Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, uninstall Max's Pitch Package, etc. That can make it worse. There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. But if you can't find it there, post your problem here.
Make sure you post in the right category below & be sure to include a screencap showing the issue!
