Note  For a description and a complete list of UI Objects, see UI Objects.

Works in combination with the data logger function to present a collection of data using time-based statistical charts. This object automatically adapts the graphical layout and size of the charts based on the overall object's size. The default presentation can be customized using several optional attributes. A datalogger can have a browser mode (if available server-side) for consulting past data. If a datalogger in browser mode isn't visible for more than a minute, it automatically resets to live mode.

Multiple datalogger ids can also be specified. Specific attributes address this behavior, like list, names and multirange.

Parameters

  • id: the object's ID, used by UISets. Required
  • loggerID: the datalogger ID (or multiple IDs)
  • position: the object's position. Use the pixels or rows and columns coordinates format
  • size: the chart's area's width and height
  • unit: list of values axis labels. If the datalogger has slots, one unit for each slot. If there are multiple datalogger ids, one unit for each datalogger
  • attributes: list of UI attribute names and values defining the chart's aspect and data. Setting this parameter is the same as setting each UI attribute with a UISet

Syntax

(datalogger[!<id>] <loggerID>; <pos>; <width>; <height>; <label>; <attributes>)

E.g.

(datalogger!datalogger1 edl; x80y60; 820; 500; kWh; controls=toolbar)

UI Attributes
