plot.spwb_day: Displays simulation results for one day

Description

Functions to plot the results of the soil water balance model for one day (see spwb_day) or the transpiration calculations with Sperry (see transp_transpirationSperry).

Usage

# S3 method for spwb_day
plot(x, type="PlantTranspiration", bySpecies = FALSE, xlab = NULL, ylab = NULL, ...)
# S3 method for pwb_day
plot(x, type="PlantTranspiration", bySpecies = FALSE, xlab = NULL, ylab = NULL, ...)

Arguments

x

An object of class spwb_day or pwb_day.

type

The information to be plotted:

• "LeafPsi":Leaf water potential.

• "StemPsi":(Upper) stem water potential.

• "RootPsi":Root crown water potential.

• "StemPLC":(Average) percentage of loss conductance in the stem conduits.

• "StemRWC":(Average) relative water content in the stem symplasm.

• "LeafRWC":Relative water content in the leaf symplasm.

• "SoilPlantConductance":Overall soil plant conductance (calculated as the derivative of the supply function).

• "PlantExtraction": Water extracted from each soil layer.

• "PlantTranspiration": Plant cohort transpiration per ground area.

• "PlantTranspirationPerLeaf": Plant cohort transpiration per leaf area.

• "PlantPhotosynthesis": Plant cohort daily net photosynthesis per ground area.

• "PlantPhotosynthesisPerLeaf": Plant cohort daily net photosynthesis per leaf area.

• "PlantWaterBalance": Difference between water extraction from the soil and transpired water per ground area.

• "PlantAbsorbedSWR": Absorbed short wave radiation per ground area (differentiates sunlit and shade leaves).

• "LeafTranspiration": Instantaneous transpiration per leaf area (differentiates sunlit and shade leaves).

• "LeafPhotosynthesis": Instantaneous net photosynthesis per leaf area (differentiates sunlit and shade leaves).

• "LeafAbsorbedSWR": Absorbed short wave radiation per leaf area (differentiates sunlit and shade leaves).

• "LeafVPD": Leaf vapour pressure deficit (differentiates sunlit and shade leaves).

• "LeafStomatalConductance": Leaf stomatal conductance (differentiates sunlit and shade leaves).

• "LeafTemperature": Leaf temperature (differentiates sunlit and shade leaves).

• "LeafCi": Leaf intercellular CO2 concentration (differentiates sunlit and shade leaves).

• "LeafIntrinsicWUE": Leaf intrinsic water use efficiency, i.e. the ratio between instantaneous photosynthesis and stomatal conductance (differentiates sunlit and shade leaves).

• "Temperature": Above-canopy, inside-canopy and soil temperature.

• "CanopyEnergyBalance": Canopy energy balance components.

• "SoilEnergyBalance": Soil energy balance components.

bySpecies

Allows aggregating output by species, before drawing plots. Aggregation can involve a sum (as for plant lai or transpiration) or a LAI-weighted mean (as for plant stress or plant water potential).

xlab

x-axis label.

ylab

y-axis label.

...

Additional parameters for function plot.
