Description Usage Arguments Value Examples

Create a heatplot for flow and cease-to-flow periods in a daily time-series.

1 2	ctf_heatmap(df, threshold = 0, units = "ML/day", format = "%d/%m/%Y", cols = c(1, 2))

`df`	A dataframe with date in the first column (as character) and discharge in the second (can be modified with cols.
`threshold`	The threshold used to indicate cease to flow.
`units`	The units of the time series (used for the y-axis label).
`format`	The date format used (default = '%d/%m/%Y').
`cols`	The columns of the Date and discharge fields (default = c(1,2)).

A ggplot object.
