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.

  • position: the object's position. Use the pixels or rows and columns coordinates format
  • size: the chart's area's width and height
  • label: the values axis label
  • attributes: list of UI attribute ids and values defining the chart's aspect and data. Setting this parameter is the same as setting each UI attribute with a UISet
