gaugeChart: Gauge Chart

In mlkornexl/gridGaugeChart: Gauge Charts Using Grid

Description

Plot gauge charts using grid graphics package.

Usage

gaugeChart(value, min, max, sectors = gaugeChartSectors(), header, label,
  gp = gpar(), vp, fmt = NULL)

.gaugeHeader(header, vp)

.gaugeDisplay(x, min = 0, max = 1, label = NULL, fmt = NULL,
  gp.beam = gpar(), vp)

.gaugeAxis(min = 0, max = 1, label = NULL, fmt = NULL, r = c(0.6, 1),
  n = 5)

.gaugeBeam(x, r = c(0.6, 1), gp = gpar())

Arguments

value	numeric, value to display
min, max	numeric, minimum and maximum value for gauge chart axis
sectors	an object of gaugeChartSectors-class specifying the the sectors for gaug chart axis
header	string, header of the gauge chart, see header section below
label	string, label for the gauge chart axis
gp	an object of class gpar
vp	an viewport object defining the plot region for the gauge chart, see viewports section below
fmt	opional format string, if supplied, the value and axis ranges min/max will be formatted using sprintf
gp.beam	an object of class gpar specifying the gauge chart's beam's color
r	numeric, inner and outer radius for gauge chart axis
n	number of steps for the shading of the axis background

Functions

• .gaugeHeader: Plot the gauge chart's header.

• .gaugeDisplay: the main auxilliary function for plotting gauge charts.

• .gaugeAxis: Plot the gauge chart's axis.

• .gaugeBeam: Plot gauge chart's beam.

Viewports

The different parts of the gauge chart will be shown in separate viewports. All viewports inherit from the parent viewport vp. If vp is not given, the current plot region will be taken as paren viewport.

The gauge chart will be displayed in a separate viewport with aspect ratio (i.e. width to height) of 2. The viewport will be fitted in 95 parent viewport's width and height.

The axis labels will be plotted below the viewport with an offset of unit(0.5, "lines").

Header

If header is given, the gaug chart's viewport will be split in two viewports. The upper one has a height of unit(4, "lines") and contains the header.

Examples

## Not run: 
sectors <- gaugeChartSectors(200, 100, 0, rev = TRUE)

pushViewport(gp = gpar(fontsize = 9, col = '#d7d7d7', fill = 'white'))

gaugeChart(125, 0, 300, header = 'Tagesanmeldungen',
    sectors = sectors, label = 'on risk')

popViewport()

## End(Not run)
