Sorry for the late response!
You can change the range limit on the map graph by altering the Averaging Period. The average defines the points on the graph (e.g. a 1-hour average will have a datapoint for every hour). The range is how many days can be displayed on the graph.
I’ll include a table of the limits below:
| Average | Graph Limit |
|---|---|
| Real-time | 2 days |
| 10-minute | 3 days |
| 30-minute | 7 days |
| 1-hour | 14 days |
| 6-hour | 90 days |
| 1-day | 1 year |
| 1-week | 5 years |
| 1-month | 20 years |
| 1-year | 100 years |
I hope that helps!
