The function constructor
is a C function that is called by a Modelica simulator
exactly once during the initialization.
The function returns the object Backend
that
will be used to store data that will be plotted to an html file.
This function has been implemented to allow mutiple plotters to write their plots to the same html file.
function constructor input String fileName "Name of html file to which this block prints"; input String instanceName "Name of the instance of this plotter"; input Integer nDbl "Number of double values in the array that is sent at each sampling time"; output Backend plt "Pointer to data structure for this plotter"; end constructor;
