The Absolute Gamma Chart shows which strikes have the largest outstanding gamma. On the x-axis we have strike price and on the y-axis we have gamma notional values. Within the bars, the orange color represents call gamma while the blue color represents put gamma. The larger the bars, the larger their impact for support or resistance. Additionally, you want to look at the clustering of levels and where they are filling in on the chart. When the price approaches or enters one of these zones where Gamma is higher, it becomes stickier, therefore reducing volatility and keeping the price around this level.

To customize your view, you can click on the upper right to filter these by either the current expiration or the next expiration. Again, the goal of this chart is to inform you of where there is the most outstanding Gamma so you can adjust your positions ahead of or into large expirations.
