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, 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

The color of line segments and points.

high

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

low

The color name for the high 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

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 postion names in ggplot2 are top, bottom, right, and left, excluding more complex options.

Examples

p1 <- clock_chart_qnt(data = bdquake, time = hms, len = depth,
Col = mag, high = "red", low = "blue")
p1 + ggplot2::labs(color = "Depth", size = "Magnitude",
title = "Earthquakes in Bangladesh since 2023")
