## Bar Chart: Causal and Non-Causal Error Comparison Across Methods and Scenarios
### Overview
The image contains two sets of grouped bar charts comparing causal and non-causal error rates across eight scenarios (FOU, FOS, FEU, FES, POU, POS, PEU, PES) for three methods: ERM (blue), ICP (orange), and IRM (green). The y-axis uses a logarithmic scale (10^-3 to 10^0), and error bars indicate variability.
### Components/Axes
- **X-axis**: Scenarios (FOU, FOS, FEU, FES, POU, POS, PEU, PES)
- **Y-axis (Left)**: Error magnitude (log scale: 10^-3 to 10^0)
- **Y-axis (Right)**: Error magnitude (linear scale: 10^-1 to 10^0)
- **Legend**:
- Blue: ERM
- Orange: ICP
- Green: IRM
- **Error Bars**: Vertical lines atop bars showing standard deviation
