The FootPrint chart shows volume at price on the buy and sell side. Most traders that use FootPrint charts are comparing sell orders at one price with buy orders at the price above. This is because these prices are trading at the same time. Jigsaw by default comes with "Tilt Mode" on (see image below) to make that comparison intuitive. The tilt shows pairs trading at these 2 prices.
We can see in the above diagram we have pairs of numbers at each time/price. Buys on the left x Sells on the right.
The number highlighted in Yellow represents an above average imbalance and the yellow square highlights the last traded price.

Volume Profile Graded - The histogram will be a color graded volume profile (with red for down bars and blue to up bars as default)
