QGIS Algorithm provided by QGIS Polar plot (qgis:polarplot). This algorithm generates a polar plot based on the value of an input vector layer. Two fields must be entered as parameters: one that define the category (to group features) and another one with the variable to plot (this has to be a numeric one)

qgis_polarplot(
  INPUT = qgisprocess:::qgis_default_value(),
  NAME_FIELD = qgisprocess:::qgis_default_value(),
  VALUE_FIELD = qgisprocess:::qgis_default_value(),
  OUTPUT = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

INPUT

source - Input layer. Path to a vector layer.

NAME_FIELD

field - Category name field. The name of an existing field. ; delimited list of existing field names.

VALUE_FIELD

field - Value field. The name of an existing field. ; delimited list of existing field names.

OUTPUT

fileDestination - Polar plot. Path for new file.

further parameters passed to qgisprocess::qgis_run_algorithm()

.complete_output

logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.

.quiet

logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.

.messages

logical specifying if messages from qgisprocess::qgis_run_algorithm() should be printed (TRUE) or not (FALSE). Default value is FALSE.
