Time Series Chart

Commonly used chart structure, displaying a number of time series

Controls

• Time

       Determines the X-Axis.

NOTE Changing these values will cause the chart to be redrawn with new data to reflect the adjusted date range

• From - Date selector. The earliest timestamp to include in chart ( Minimum X value )
• To - Date selector. The latest timestamp to include in chart ( Maximum X value ). NOTE Defaults to 'now'
• Value

       Determines the Y-Axis

       NOTE Changing these values does not require new data, but will alter which values are displayed

• Minimum Value - Left side of slider, related value is first number in box above the slider (Minimum Y value)
• Maximum Value - Right side of slider, related value is second number in box above the slider (Maximum Y value)

• Hold Values
• Show All Series
• This is an optional control on some instances of this chart. Selecting this toggle will switch the chart to a view of all the underlying sensor data and not a combined 'best' line for a site-parameter combination. Helpful to notice disparity or failures in different sensors

Tools

• View in Table

       Displays the underlying data as table in a new browser tab. Rows are timestamps, while Columns correspond to the time series in the chart.

• Save as CSV

       Downloads the underlying data as a CSV file, in the same  row and column format as the 'View in Table'.

• Screenshot

       Downloads a screenshot of the chart as it is currently displayed.

Legend

There is an entry in the legend for each time series included in the chart, with colored marker that corresponds to the related line in the chart.

Clicking on one of these legend entries will toggle the visibility of the related line. Hidden lines are marked with a strike-through.
