The current graph X-Axis labels are hard to read with several issues:

• European dates only (hard for us Americans)
• No obvious day breaks (when day rolls over)
• Date only no day of week (we think in days of week, not dates)

Improvements would be:

• Option to set graph date format to US/EU
• Add Day of Week letter on day (MTWRFSU)
• Add two level label so date only shown at midnight, all other data points are time only.

We've done this for years on our system with simple PHP change. See attached image.
