## Open the System Characterization results directory
Arm Performix also provides a link to the underlying Arm System Characterization Tool run directory. By following this link, you can inspect plots that are not yet available in the GUI. You can also access the underlying `\.json` data files for integration with other tools.

Select the **Open Run Directory** button on the **Summary** page of your run.

*Summary view with the Open Run Directory button*

This opens a file browser that contains `\.png` and `\.json` files for the various benchmarks.

## Inspect the generated plots

### Latency sweep
The latency sweep plot shows how the size of a memory access pattern affects memory latency. Red bars indicate the points at which different cache levels become active.

### Bandwidth sweep
The bandwidth sweep plot shows how certain memory access sizes can significantly affect system memory bandwidth. The results are saved in `bandwidth.png`.

### Core-to-core latency
The `core_latency_heatmap_local.png` plot shows a color-coded heatmap of which core combinations incur higher latency.
