<h2>Color Palette Demonstration Plot</h2>

<h3>Description</h3>

<p>Demonstration of color palettes in various kinds of statistical graphics.
</p>

<h3>Usage</h3>

<pre>
demoplot(x, type = c("map", "heatmap", "scatter", "spine", "bar", "pie",
  "perspective", "mosaic", "lines"), ...)
</pre>

<h3>Arguments</h3>

<table summary="R argblock">
<tr valign="top"><td><code>x</code></td>
<td>
<p>character vector containing color hex codes.</p>
</td></tr>
<tr valign="top"><td><code>type</code></td>
<td>
<p>character indicating the type of demonstration plot.</p>
</td></tr>
<tr valign="top"><td><code>...</code></td>
<td>
<p>currently not used.</p>
</td></tr>

<h3>Details</h3>

<p>To demonstrate how different kinds of color palettes work in different
kinds of statistical displays, <code>demoplot</code> provides a simple convenience
interface to some base graphics with (mostly artificial) data sets.
All types of demos can deal with arbitrarily many colors. However, some
displays are much more suitable for a low number of colors (e.g., the pie
chart) while others work better with more colors (e.g., the heatmap).
</p>

<h3>Value</h3>

<p><code>demoplot</code> returns invisibly what the respective base graphics
functions return that are called internally.

<h3>Examples</h3>

<pre>
## all built-in demos with the same sequential heat color palette
par(mfrow = c(3, 3))
cl &lt;- sequential_hcl(5, "Heat")
for (i in c("map", "heatmap", "scatter", "spine", "bar", "pie", "perspective", "mosaic", "lines")) {
  demoplot(cl, type = i)
}

## qualitative palettes: light pastel colors for shading areas (pie)
## and darker colorful palettes for points or lines
demoplot(qualitative_hcl(4, "Pastel 1"), type = "pie")
demoplot(qualitative_hcl(4, "Set 2"), type = "scatter")
demoplot(qualitative_hcl(4, "Dark 3"), type = "lines")

## sequential palettes: display almost continuous gradients with
## strong luminance contrasts (heatmap, perspective) and colorful
## sequential palette for spine plot with only a few ordered categories
demoplot(sequential_hcl(99, "Purple-Blue"), type = "heatmap")
demoplot(sequential_hcl(99, "Reds"), type = "perspective")
demoplot(sequential_hcl(4, "Viridis"), type = "spine")

## diverging palettes: display almost continuous gradient with
## strong luminance contrast bringing out the extremes (map),
## more colorful palette with lower luminance contrasts for displays
## with fewer colors (mosaic, bar)
demoplot(diverging_hcl(99, "Tropic", power = 2.5), type = "map")
demoplot(diverging_hcl(5, "Green-Orange"), type = "mosaic")
demoplot(diverging_hcl(5, "Blue-Red 2"), type = "bar")

## some palettes that work well on black backgrounds
par(mfrow = c(2, 3), bg = "black")
demoplot(sequential_hcl(9, "Oslo"), "heatmap")
demoplot(sequential_hcl(9, "Turku"), "heatmap")
demoplot(sequential_hcl(9, "Inferno", rev = TRUE), "heatmap")
demoplot(qualitative_hcl(9, "Set 2"), "lines")
demoplot(diverging_hcl(9, "Berlin"), "scatter")
demoplot(diverging_hcl(9, "Cyan-Magenta", l2 = 20), "lines")
