### Represent a PlotItem that gnuplot treates as a file. This class holds the information that is needed to construct the plot command line, including options that are specific to file-like gnuplot input. <filename> is a string representing the filename to be passed to gnuplot within quotes. It may be the name of an existing file, `-` for inline data, or the name of a named pipe. #### Keyword arguments: `using=<int>` plot that column against line number `using=<tuple>` plot using a:b:c:d etc. Elements in the tuple that are None are output as the empty string. `using=<string>` plot `using <string>' (allows gnuplot's arbitrary column arithmetic) `every=<value>` plot `every <value>`. <value> is formatted as for `using` option. `index=<value>` plot `index <value>`. <value> is formatted as for `using` option. `binary=<boolean>` data in the file is in binary format (this option is only allowed for grid data for splot). `smooth=<string>` smooth the data. Option should be `unique`, `csplines`, `acsplines`, `bezier`, or `sbezier`. The keyword arguments recognized by `PlotItem` can also be used here. Note that the `using` option is interpreted by gnuplot, so columns must be numbered starting with 1. By default, gnuplot uses the name of the file plus any `using` option as the dataset title. If you want another title, set it explicitly using the `title` option.
