plot_TH function

Graph: Climate chart of temperature and humidity

The plot_TH function allows the user to build a column/line graph with climatic parameters of temperature (maximum, minimum and average) and relative humidity (UR) or precipitation. This chart is widely used in scientific work in agrarian science

plot_TH(
  tempo,
  Tmed,
  Tmax,
  Tmin,
  UR,
  xlab = "Time",
  yname1 = expression("Humidity (%)"),
  yname2 = expression("Temperature ("^o * "C)"),
  legend.H = "Humidity",
  legend.tmed = "Tmed",
  legend.tmin = "Tmin",
  legend.tmax = "Tmax",
  colormax = "red",
  colormin = "blue",
  colormean = "darkgreen",
  fillbar = "gray80",
  limitsy1 = c(0, 100),
  x = "days",
  breaks = "1 months",
  textsize = 12,
  legendsize = 12,
  titlesize = 12,
  linesize = 1,
  date_format = "%m-%Y",
  sc = 2.5,
  angle = 0,
  legend.position = "bottom",
  theme = theme_classic()
)

Arguments

• tempo: Vector with times
• Tmed: Vector with mean temperature
• Tmax: Vector with maximum temperature
• Tmin: Vector with minimum temperature
• UR: Vector with relative humidity or precipitation
• xlab: x axis name
• yname1: y axis name
• yname2: Secondary y-axis name
• legend.H: Legend column
• legend.tmed: Legend mean temperature
• legend.tmin: Legend minimum temperature
• legend.tmax: Legend maximum temperature
• colormax: Maximum line color (default is "red")
• colormin: Minimum line color (default is "blue")
• colormean: Midline color (default is "darkgreen")
• fillbar: Column fill color (default is "gray80")
• limitsy1: Primary y-axis scale (default is c(0,100))
• x: x scale type (days or data, default is "days")
• breaks: Range for x scale when x = "date" (default is 1 months)
• textsize: Axis text size
• legendsize: Legend text size
• titlesize: Axis title size
• linesize: Line size
• date_format: Date format for x="data"
• sc: Scale for secondary y-axis in relation to primary y-axis (declare the number of times that y2 is less than or greater than y1, the default being 2.5)
• angle: x-axis scale text rotation
• legend.position: Legend position
• theme: ggplot2 theme

Returns

Returns row and column graphs for graphical representation of air temperature and relative humidity. Graph normally used in scientific articles
