As described in Dashboard: Adjusting chart preferences for dashboard widgets, users can customize their current dashboard charts or add new charts for a sensor. One such chart shows recorded data over time, or time series. To create a time series chart, first click New Chart.
In the Chart Settings pane, choose the device and sensor you would like to view data for.
Give your chart a name or leave the default sensor name in place. Set the position priority of the chart so that it does not collide with any existing chart positions. If you're unsure, the system will inform you of any collisions upon Save, giving you the opportunity to adjust the priority number.
Choose Time Series from the Chart Type dropdown menu. Note that you must have data recording for a sensor in order to display a time series chart appropriately. If there is no recorded data, your time series chart will be blank. We've made it very easy to begin recording data by putting the checkbox to record sensor data right below the Chart Type dropdown when Time Series is chosen.
If you are already recording data for the chosen sensor, you will not see the warning text below the Record data checkbox and the checkbox will be checked.
You may adjust the minimum and maximum values to give the values to the Y axis of your time series chart. The X axis is pre-defined by the system in preset time increments. Click Save to view your time series chart.
Click the time increment buttons at the bottom of the chart to cycle through the time scales. Note that this is a line graph, meaning that any missing data in longer-term views (6 months or more) will have a line drawn between recorded values.
At any point, you may go into the time series chart settings and restore the default values of the originally created chart by clicking Reset to Defaults. To remove a chart, simply press the trash can icon on the chart in the dashboard.
