Clock Chart, Length and Color Modified by Numeric Variables

This function will plot time of events on a 24 hour clock to show which events took place at what times. The length and color of the hands are modified according to a numeric vector.

Usage

clock_chart_qnt(data, time, len, Col = NULL, high = "red", low = "green")

Arguments

data

A data frame

time

Time in 24 hours. The allowed time formats for these family of charts are HH:MM:SS, HH:MM or even H:M (such as 12;30:09 or 9:3).

len

The numeric vector by which hands will be modified and colored.

Col

Optional. A numeric vector to change color. This option will be discontinued.

high

The color name for the high values. The default is red.

low

The color name for the low values. The default is green. The color names can be vice versa or other colors, depending on the context. To use a single color for all lines, use same value for high and low.

Value

A ggplot object, which can be further modified with ggplot2 functions and themes.

Details

Change the title, subtitle or the caption of the plot with ggplot2::labs() .Change the legend title by adding ggplot2::labs(color = "TITLE 1", size = "TITLE2"). Add or modify legend by theme(legend.position = "POSITION"); the valid position names in ggplot2 are top, bottom, right, and left, excluding more complex options.

  Col = mag, high = "red", low = "blue"
)
p1 + ggplot2::labs(
  color = "Depth", size = "Magnitude",
  title = "Earthquakes in Bangladesh since 2023"
