Datalogger

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.

Parameters

• id: the object's ID, used by UISets. Required
• 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

Syntax

(datalogger <id>; <pos>; <width>; <height>; <label>; <attributes>)

E.g.

(chart!chart1 x3y187; 312; 180; (type=line; values=0,10,24,12,7,35,42,1,23,4))
