Class
    Foam::functionObjects::LagrangianDistribution
 
Description
    Function to generate a plot of the distribution of the values in a
    Lagrangian field
 
Usage
    \table
        Property      | Description                  | Required? | Default
        Lagrangian    | Name of the Lagrangian mesh  | yes       |
        field         | Field to operate on          | if fields not specified |
        fields        | List of fields to operate on | if field not specified |
        weightField   | Field with which to weight the distribution | no | none
        weightFields  | List of fields with which to \
                        weight the distribution      | no        | none
        nBins         | The number of bins used in the plot | yes |
        setFormat     | Format of the plot file      | yes       |
    \endtable
 
    Example specification to generate the diameter distribution:
    \verbatim
    LagrangianDistribution1
    {
        type            LagrangianDistribution;
        libs            ("libLagrangianFunctionObjects.so");
        Lagrangian      cloud;
        field           d;
        weightField     number;
        nBins           20;
        setFormat       raw;
    }
