What it is
League of Graphs is a statistical analysis platform for League of Legends operated from France, active since around 2014. Its distinctive angle from the start was presenting data visually — graphs, temporal evolutions, legible infographics — in an era when most stats sites showed flat tables of numbers.
Its central value is historical depth: the tool stores aggregated data across many patches and lets you see how any metric (win rate, pick rate, ban rate, build path) evolved over time, with annotations on the balance changes that drove each movement. It also has record leaderboards (longest registered matches, most kills, most assists, etc.) and curious-stats sections that no other tool in the ecosystem shows (pentakill probability by champion, match duration distribution by rank).
It's free, ad-funded. No paid tier, and feature coverage is complete for any user without login.
What problem it solves
If you want to know Yasuo's current win rate, several tools give you that number. But if you want to know how that win rate evolved across the last 6 patches, which balance changes drove which spikes, or how Yasuo's trajectory compares to other mid-laners, the options shrink drastically. Lolalytics has lots of data but its editorial focus is the current patch; OP.GG/U.GG-style sites refresh per patch without easily retaining the historical trajectory.
League of Graphs covers exactly that gap: temporal depth with clear visualization. For players who want to understand the meta as an evolving phenomenon —not just the current-patch snapshot— this tool is the reference.
Lolalytics and League of Graphs cover adjacent territory and complement each other: Lolalytics for granular tactical analysis of the current patch, League of Graphs for historical depth and statistical curiosities. See the "The difference with League of Graphs" section on Lolalytics for the full comparison.
What people use it for
Champion evolution tracking across patches: most distinctive use case. Look at a champion and see its win-rate graph for the last 12 patches, with markers for when it received buffs/nerfs and how the community responded.
Records and curiosity research: who registered the longest-match record, which champion has the highest pentakill probability, how average match duration varies by rank. Useful for content and community debate.
Same-role champion comparison: side-by-side view of win rate, pick rate, and other indicators across multiple champions of the same role — more visually legible than Lolalytics's flat tables.
Pedagogical tier lists: League of Graphs's tier list includes per-tier breakdowns (S+, S, A, etc.) with visual explanation of the why — useful for players learning to read tier lists.
Player and competitive-team stats: although not its main focus, it also has summoner profiles with attractive visual dashboards.
Who this tool isn't for
League of Graphs is excellent for historical analysis and visualization, but isn't what you need if:
- You want granular current-patch breakdowns → Lolalytics is deeper (filters by skill cap, by composition, by timing) for immediate tactical analysis.
- You want a quick build guide → U.GG is cleaner and more direct for that specific function.
- You want dense personal match history → OP.GG is more complete on individual profiles.
- You want structured coaching → Mobalytics has the GPI; League of Graphs doesn't go into that territory.
How it's used in practice
Go to
leagueofgraphs.com(no login).Search for a champion or browse the home, which highlights tier lists and "Records" / "Statistics" sections.
Champion view shows: current win rate, but also evolution graph of the last N patches, with buff/nerf markers on each relevant change.
Additional tabs: Builds (with build-path evolution timeline), Matchups, Counters, Tips.
General "Statistics" section (accessible from top nav) has the pedagogical breakdowns: match duration distribution, comeback probability, pentakill frequency, etc.
"Records" section (also top nav) lists the leaderboards of extreme matches — useful for content or curiosity.
For recurring use: bookmark your main's URL to check evolution each patch, and the general Statistics section for community data.
Honest limitations
Visible ads: the tool is 100% free and sustained by ads. On desktop with an ad-blocker it's manageable; on mobile it can become annoying.
Less filter depth than Lolalytics: for granular tactical analysis (win rate by skill cap, by specific composition), Lolalytics offers more controls. League of Graphs trades some granularity for cleaner visualization.
Smaller-region datasets are less representative: like the rest of the ecosystem, KR/NA/EUW are solid; LAS/LAN/OCE/BR can have gaps in temporal aggregates.
No desktop app or overlay: League of Graphs is web-only. If you want client integration or active assistance, you need other tools.
Some graphs require reading time: visual presentation helps but doesn't replace interpretation. A new user may look at a win-rate evolution graph without knowing what to infer — the tool doesn't force a "takeaway" the way Mobalytics does with the GPI.
How to get started
Go to
leagueofgraphs.com. No registration.Search your main champion. Look at the win-rate evolution graph — understand what happened in recent patches and why.
Explore the general Statistics tab (top nav) — spend 10 minutes browsing community data. It's the most distinctive section of the tool.
For each new patch, return to your champion and note whether the change moved the win rate or not relative to previous patches. That gives you intuition on whether a balance change had real impact.
If you're interested in deep current-patch theorycrafting, complement with Lolalytics. The two tools cover different angles of the same statistical analysis — using both in parallel is common for mid-to-high elo players.
