Finding Leaks with Colour and Bars

In preparation for a set of new "Leak Detector" screens in Poker Copilot, I'm reading Stephen Few's "Now You See It: Simple Visualization Techniques for Quantitative Analysis". The subtitle is tedious, better would be "Make Awesome Charts."

I'm getting a lot of value from Few's book on using colour and simple charting techniques to make analysis easier. Here's what I started with:

The info is there, but you have to read and compare all numbers carefully to spot the patterns.

Step 2: I added colour to show positive and negative numbers:

Now we can immediately see that I've been losing money with 44, and winning with all other pocket pairs. But some info is still hiding, requiring careful manual analysis.

Step 3: Show the magnitude with a coloured bar:

Ho ho! Now the patterns are clear. I'm doing something wrong with TT and 99, which should be good earners: my winnings are positive but only just. Aces, Kings, Queens, Jacks are all paying out well, so I'm happy with the way I play them.

Steve,

Is this 6max or FR?

I like it. Just a comment on the last picture, the bar graph colors are a bit light, so maybe either increase the darkness of the bar graphs and/or also make the negative value still red as well for the numbers on the right column.

Are you able to filter all the hands you played 44 to review them? I have been unable to myself..

Agree with the above poster. In theory, you're supposed to be a winner with all pairs. But if you get cold decked a few times with a particular pair, it could skew the stats the other way.

Having the ability to look up each time you played a particular hand would allow to you review how you played the hand in that situation.

@Bold Bet,

I think I did this screenshot with FR? Why do you ask? Would you expect a big difference with 6-max? I'm curious to know because it might shape how I implement this feature.

@Anonymous,
"Are you able to filter all the hands you played 44 to review them? I have been unable to myself."

This is high on the list of things to do.

Steve,
I assume the numbers will be different on 6max because it's higher variance than FR.
