A comfortable Volume Indicator with the following features:
- Darker colors indicate positive changes
- Light colors indicate negative changes
- There are separate colors for changes above a configurable threshold
- The threshold can look at percentages changes in either volume (directly) or the volume at log scale.
- The graph itself is always displayed in regular format so the numbers indicate real value.
