Description Usage Arguments Details Value See Also Examples

PlotFdc plots a flow duration curve from a dataframe processed through CalcFdc and optional spline function processed through CalcFdcSpline.

1	PlotFdc(strDf, strCol = "q_cms", spline = TRUE, fdcProb = NULL)

`strDf`	The streamflow time series dataframe (e.g., output from `ReadFrxstPts` or `ReadUsgsGage`) already processed through `CalcFdc`. The data frame must contain a column of streamflow values and a corresponding column (named "<strCol>.fdc") of flow exceedance probabilities.
`strCol`	The name of the column containing the streamflow values (DEFAULT="q_cms").
`spline`	(TRUE or FALSE) Option to add spline-fit curves to the plot (DEFAULT=TRUE).
`fdcProb`	Optional exceedance threshold to calculate/plot (e.g., 0.2 for 20% exceedance).

PlotFdc reads the dataframe generated by CalcFdc and outputs a plot of flow vs. percent exceedances and, optionally the fitted spline curve.

A plot of flow (y) vs. flow exceedance probabilities (x).

## Take a time series of observed 5-minute streamflow values for Fourmile 
## Creek (stored in the dataframe obsStr5min.fc in the column "q_cms") that
## has already been processed through "CalcFdc" (so also contains a column 
## named "q_cms.fdc") and plot with the 20% exceedance threshold called out.
## Not run: 
PlotFdc(obsStr5min.fc, fdcProb=0.2)
