\note For the size, line width and symbol type columns, you can also set a functor, which converts the column value (optionally based
|
|
also on the x- and y-location of the data point) into the local symbol size, symbol type or line width. Use the functions
|
|
setLinewidthColumnFunctor(), setSymbolColumnFunctor() and setSizeColumnFunctor() to set these functors. This feature gives you
|
|
even more control over the modification of the plot elements. Initially all functors are set to default values, that do not add
|
|
any additional transformations.
