Switches

--file=FILE

This is the output image file to write to. Supported formats: bmp, cur, ico, jpeg, jpg, pbm, pgm, png, ppm, svg, xbm, xpm.

Default: output.png

--fit[=BOOLEAN]

This sets the display of the distribution fits.

Default: Enabled

--grid=TYPE

This is the grid mode to display. This enables or disables the possible grids that are shown.

Default: Disabled

The possible values are:

--grid=both

Both X and Y grid lines are displayed.

--grid=disabled

No grid is displayed.

--grid=enable

Same as --grid=both

--grid=enabled

Same as --grid=both

--grid=none

Same as --grid=disabled

--grid=off

Same as --grid=disabled

--grid=x

Only grid lines extending from the X axis are displayed.

--grid=x-y

Same as --grid=both

--grid=xy

Same as --grid=both

--grid=y

Only grid lines extending from the Y axis are displayed.

--height=INTEGER

This is the height of the output file.

Default: 768

This option only accepts integers greater than or equal to 1.

--legend=TYPE

This is the legend mode to use. This sets the position of the legend for the graph.

Default: Inside top left corner

The possible values are:

--legend=bottomleft

The legend is located inside the trace area at the bottom left corner.

--legend=bottomright

The legend is located inside the trace area at the bottom right corner.

--legend=disabled

No legend is displayed.

--legend=inside

Same as --legend=topleft

--legend=left

The legend is located outside and to the left of the graph.

--legend=none

Same as --legend=disabled

--legend=off

Same as --legend=disabled

--legend=outside

Same as --legend=right

--legend=right

The legend is located outside and to the right of the graph.

--legend=topleft

The legend is located inside the trace area at the top left corner.

--legend=topright

The legend is located inside the trace area at the top right corner.

--log[=BOOLEAN]

This changes the variable axes to be logarithmic.

--opaque[=BOOLEAN]

When enabled on an output format that supports transparency, this causes the output image to have an opaque white background instead of the normal transparent one.

--quantile=NUMBER

This causes the plot to only include the inner percentage of data set. For example, setting this to 99, causes the graph to exclude the top and bottom 0.5% of data.

This option only accepts numbers strictly greater than 0 and less than or equal to 100. Undefined values are permitted, to indicate that the option is set but not to a specific value.

--title=STRING

This is the main graph title.

--width=INTEGER

This is the width of the output file.

Default: 1024

This option only accepts integers greater than or equal to 1.

--x=VARIABLE

This is the variable or variables to plot on the X axis.

--x-title=STRING

This is the title output along the X axis.

Default: Generated from the axis units.

--y-title=STRING

This is the title output along the Y axis.

Default: Generated from the axis units.

--z=VARIABLE

This is the variable or variables that determine the trace color. This generates a continuum of colors between minimum and maximum values for the variable.

Arguments

If no bare word input specification is supplied then data are read from standard input.

station

This argument is used to specify the station used to look up variables that do not include a station as part of an archive read specification. The station is the three letter GAW station code of the location, such as BND. The argument accepts multiple stations specified as regular expressions and separated by : or ; or ,. For example BND,MLO and (BND|MLO) are two ways of selecting both the BND and MLO stations.

The special value allstations may also be specified to select all stations.

variables

This argument may be split into multiple actual program arguments. Each part consists of one or more variable specifications separated by , (commas). The station and archive used if none are explicitly given are defined in the other arguments or inferred from system defaults. For example simply BsB_S11 selects the blue scattering from the S11 instrument and returns all cut sizes and metadata. If instead ::BsB_S11:pm10 is used then only PM10 scattering is returned. That is, the selection specifies "any" station and archive (the defaults are set in the other arguments) then requires that it has the "PM10" flavor. A specification such as bnd:BsB_S11,thd:BsB_S11 allows for data selection from multiple stations.

This may also be used to select a "record" type alias such as "S11a". In this mode all the variables defined in the alias are returned.

Finally the special value everything can be used to select all available data for the given station(s) and archive(s).

times

This argument may be split into multiple actual program arguments. This full list of time arguments defines a time bounds list that sets the range of data queried. The final resulting data are clipped to the given time bounds but any values that intersect them are returned.

archive

This argument is used to specify the archive used to look up variables that do not include an archive as part of an archive read specification. The archive is the internal name, such as raw or clean_meta. The argument accepts multiple archives specified as regular expressions and separated by : or ; or ,. For example raw(_meta)? selects both the raw and raw_meta archives.

The special value allarchives may also be used to select all available archives.

file

This argument is used to specify the the file to read data from. If it is present and exists then data is read from the given file name instead of from standard input. Alternatively - (a single dash) may be used to explicitly specify standard input.
