Overview Block Statistics

This control element shows recorded values as a chart – for instance the yield of the photovoltaics over the day, room temperatures of the last week or the consumption of a year.

Operation

Statistics on the page
  1. Chart symbol: shows that a recording is available here.
  2. Value and circle: depending on the setup the current value; the circle shows it in relation to the configured range. Otherwise a large chart symbol is shown here.

A tap on the element opens the chart.

The chart

The chart
  1. Key figures: an evaluation of the visible range with Start, End, Number of data points, Minimum, Maximum and Average.
  2. Gear: opens the selection of the time range, see below. In the new design it opens the settings with the entries Key figures, Time range, Lines and Delete data.
  3. Chart: the recorded values, one line per measured value. While the data are loading, “Please wait…” appears.
  4. – and +: + zooms in horizontally and shows a section in more detail, – zooms out again.
  5. Arrows: move the period back and forward.
  6. Time range: shows the selected range; a tap opens the selection.

Choosing the time range

Choosing the time range
  1. Hour to 24 hours: the last hours up to the current time.
  2. Day to 90 days: whole days up to and including today.
  3. Week, Month and Year: the current calendar week (Monday to Sunday), the current month or the current year. The arrows move by one week, one month or one year.
  4. Date opens the dialog Time range, in which start (From) and end (To) are set freely.
  5. Lines: shows and hides individual lines with the tick.
  6. Delete: deletes all recorded data of this statistic after a confirmation. This cannot be undone.

In the new design, Lines and Delete data are separate entries in the settings behind the gear. One switch per line shows or hides it in the chart at once. Delete data asks in a sheet of its own; only Delete permanently removes the data, the cross cancels.


Setup

This section is meant for the installer of the system.

The control element is linked to the function block Statistics block, which records the values: first create the function block and its addresses, then right click on the control element and select the function block. Without a link a tap on the element points this out. See also the notes under Project statistics.

Parameters

Display
View Block or Basic Screen. The third choice List (deprecated) comes from older projects and should no longer be used.
Text Caption of the tile. Its size scales with the element, a line break is inserted with \n, two lines at most.

Chart
Background / Font Colours of the chart.
Legend Shows the names of the lines in the chart.
Scaling min. / max. Fixed range of the Y axis. If both are 0, the axis is scaled automatically.
Decimal places Y Decimal places of the Y axis labels.
Parameter The button “…” opens the settings of the lines. Per line: Active (show), Name (in the legend), Type (linear, rectangle, linear+fill, rectangle+fill or bar), width and colour, plus Factor and Offset for converting the raw value. With the type bar, the width of each bar follows the distance to the closest value. Lines without a colour automatically get one of their own that stands out against the chart background; Colours automatic redistributes the colours of all lines.

Progress/value
Show Do not show (default: symbol only), Value+Progress or Value only on the tile.
Format Format of the number, see Format specifications. Default %.1f.
Type Linear: the circle fills from minimum to maximum. Plus/Minus: positive values fill one half of the circle, negative values the other – for grid import and export, for instance.
Minimum / Maximum Range of the circle, default 0 to 100.
Factor The value is multiplied by this factor, for instance 0.001 from watts to kilowatts. It affects number and circle; at 0, 1 applies.
Positive + / Negative - Colours of the circle for positive and negative values.

Address links

The recorded values come from the function block.

Value display Optional. Value for number and circle on the tile. Not linked: 0 is shown.

Tip: If the tick Background under transparency is removed, only the symbol remains – that makes it easy to lay the element over another one.
