Optional. If specified, then for this component the height attribute is linked to the data values for the specified variable. This option can only be used for svg objects of type "rect". The data limits refer to the range of the timeseries. The height limits refer to the height of the object within the svg file for the unit (e.g. pixels or mm) defined in the document properties. If the data value is less than dataLowerLimit, then the height is set to heightLowerLimit. If the data value is greater than dataUpperLimit, then the height is set to heightUpperLimit. If the data value is between dataLowerLimit and dataUpperLimit, then the height will be linearly interpolated between heightLowerLimit and heightUpperLimit. If no data is available, then this component is made invisible.
