Plots Bagnouls - Gaussen climatic charts of precipitation and temperature. Conventionally, in this chart the scale of precipitation has a double extension with respect to the scale of temperature (Bagnouls and Gaussen, 1953).

bagn_gau(clim_norm_sta, save_dir = NULL, format = NULL, main_title = NULL,
  st_name = NULL, trace_grid = TRUE, tick_step = 20, bar_width = 30,
  bar_col = "grey", trace_0.line = TRUE, ...)

`clim_norm_sta`	data frame with climatic normals
`save_dir`	name of destination directory for graphs (if any).
`format`	graphical format of graphs; default is NULL.
`main_title`	main title for all charts; e.g., it may include references to station id. Default is `NULL`.
`st_name`	name to be included into graphs titles. Only for file output. Default is `NULL`.
`trace_grid`	logic. If `TRUE` (default) adds a grid.
`tick_step`	step for Y axis (precipitation). Default is 20 (mm)
`bar_width`	width of bars in the chart. Default is 30.
`bar_col`	color of bars. Default is "grey".
`trace_0.line`	logic. If `TRUE` (default), a line at P = 0 and T = 0 is traced.
`...`	arguments to be passed to methods, such as graphical parameters (see `par`).

clim_norm_sta can be e.g. one element of the output of function climate. See examples.

If format is NULL (default), graphs are sent to the console. Otherwise, a file is produced and saved. format is used only if the graphs are to be sent to files. Values allowed are: "png", "jpeg", "tiff", "bmp".

If one or more data are missing, the chart is not processed.

Most graphic parameters for functions plot, axis, and mtext are accepted.

Bagnouls - Gaussen's charts of precipitation and temperature.

A conflict is generated if parameters already used by the function are passed (e.g. col - use col.main, col.axis, ..., instead).
