 By default, line charts show data over a range of time. The selected time range is split into 50 equally sized partitions. The device data is then aggregated per partition to give 50 data points over the selected time range. If you want to view raw data, you can change your selection to view the last 100 values. To change the time range or to select raw data visualization, use the **Display range** dropdown in the **Configure chart** panel.
