  colBar = NULL, colLine = NULL, legend = NULL, ...)

`effort1`	A vector of the first serie of fishing effort.
`effort2`	A vector of the second serie of fishing effort.
`labAxis2`	Text to be included on the left vertical axis of the graph
`labAxis4`	Text to be included on the right vertical axis of the graph
`colBar`	The colour of the barplot. Sea `barplot`.
`colLine`	The colour of the line on the graph.
`legend`	The names to include on the legend of the graph.
