Tendency interface picture. Each player has their own color box. Each box consists of 4 rows that represent preflop/flop/turn/river. Topmost row is preflop. The numbers on each row is the sum of all actions on each street, so far in the game. An action is one of the following ones: folding/checking/calling/betting/raising. Lets say a player1 calls preflop, then some-other player raises behind him, if he decides to call this raise, then he has two actions so far on this street in this specific hand. The dashed lines represent, from left to rigth, 20/40/60/80 percent of the actions performed on each street. By looking at these lines one can quickly get a overview of how many hands a player raises vs folds, and so on. Then we have the last bit of information in the box, the colors. 

• Blue = Folding
• Gray = Checking
• Pink = Calling
• Green = Betting
• Red = Raising
