qgis_vectorlayerhistogram.Rd
QGIS Algorithm provided by QGIS Vector layer histogram (qgis:vectorlayerhistogram). This algorithm generates a histogram with the values of the attribute of a vector layer. The attribute to use for computing the histogram must be a numeric attribute.

)
source
- Input layer. Path to a vector layer.
field
- Attribute. The name of an existing field. ; delimited list of existing field names.
number
- number of bins. A numeric value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.
fileDestination
- Histogram. Path for new file.
further parameters passed to qgisprocess::qgis_run_algorithm()
logical specifying if complete out of qgisprocess::qgis_run_algorithm()
should be used (TRUE

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