My own opinion and interpretation.
Chart made in MS Excel

Normal volume in blue, pushing up with the scale to the right (and average line in red)
DSS (daily short sales) in red, pushing down
Both are relative to each other (same size scale)

Short Interest in yellow as an area chart with scale to the left (not in the same scale as normal volume and DSS)

All volumes include both ASX and ChiX volumes.

A price wave is the thin red line across the price bars - wave size at Top Left - shows the waves of buying selling in the market (from daily closes with no fixed time period)
On top of the red DSS, is cumulative volume, which shows the accumulated normal volume for each price wave, red for down or supply waves, and blue for up or demand waves.

Any hollow proportion of a bar is a price gap (close to close).
