#CONNECTSTO: The integer numbers which follow CONNECTSTO represent a pane in the realtime dashboard. When clicked on that pane this chart appears. This is only valid on charts in the default output. For other outputs there is no semantics for CONNECTSTO and a warning is issued in the logfile if it is specified in any second or higher output.

The keywords for the actual parameters and the Graph Types speak for themselves.

===== STATS =====

The STATS plots a statistic in the chart. The normal PLOT of that variable must be present. STATS implies the ALL or DAILY range specification. RECENT PLOTS have no STATS (at the moment).
The following example shows the Rain for all days (all observations). In addition the yearly cumulative curve is shown and the moving average (SMA - Simple Moving Average). See image on the right.
  CHART DailyRain TITLE Rain with statistics
    PLOT ALL RainFall colour CornflowerBlue as column
    PLOT ALL RainFall EVAL [ SUM( RainFall ) ] COLOUR crimson AXIS Free
    STATS RainFall SMA colour green
