yeah I liked the old version much better, it was user friendly showed a complete trend. it also showed a highest and lowest. please bring the old TT graph back.
Tactics Trainer graph
I agree. The new TT gragh is so appalling that I assumed there was something wrong with my PC (oh, yeah! The browser...)
Bring back that which did not need fixing.
I remember one of the bits of wisdom that my father gave me (and still gives me) is if it ain't broke don't fix it.
that totally aplys here.
I do like the new graph, but I have to admit I also do miss the old information being there as well.
I also think there's a small bug in the graph. The "opening" rating for each day seems to be the rating after the first puzzle of the day, whereas I think it should the closing rating of the previous day. For instance, if you close yesterday at 2,005, solve the first puzzle and hit 2,017, but then close at 2,010 after doing a bunch more puzzles, the graph for that day will show a decrease of 7 points, whereas I think it should show an increase of 5.
Maybe they changed it because the majority of users voted for the new one. Otherwise why would they implement something so ugly and totally not understandable?
Or maybe the chess.com programmers have to justify their salaries so they come out with stuff nobody asked for, no matter what the users really want.
I also prefer the previous one, just in case I wasn't clear! 
Agree. Like the old one. This new one is more suitable for the financial pages, although I do like the slider which allows you to choose the range of the graph.
I like the new graph. I think if you guys spent a little time with it, you would too. BTW I'm 66 and such a confirmed Luddite that I don't even carry a cell phone so it's not like you need to be a technology whiz kid to figure it out. There is a lot more information available on your daily progress, and in the final analysis what difference does it really make? TT still remains one of the more humbling experiences available in the chess world.

I find the new graph system in the tactics trainer totally alien, and difficult to understand. I don't understand if the red and blue are used for showing how some political parties are winning or losing the elections, or maybe some football games. And frankly if I have to read about it, in order to understand it, well it is not user friendly.
Is there any way to return to the graph that there was before? It was clear, and there was the last rating nearby, plus I was able to see how many positions I made, how many I solved, and how many I missed, there were also the hours.
