<h2>Set guides for each scale</h2>

<h3>Description</h3>

<p>Guides for each scale can be set scale-by-scale with the <code>guide</code>
argument, or en masse with <code>guides()</code>.
</p>

<h3>Usage</h3>

<pre>
guides(...)
</pre>

<h3>Arguments</h3>

<table summary="R argblock">
<tr valign="top"><td><code>...</code></td>
<td>
<p>List of scale name-guide pairs.  The guide can either
be a string (i.e. &quot;colorbar&quot; or &quot;legend&quot;), or a call to a guide function
(i.e. <code><a href="guide_colourbar.html">guide_colourbar()</a></code> or <code><a href="guide_legend.html">guide_legend()</a></code>)
specifying additional arguments.</p>
</td></tr>
</table>

<h3>Value</h3>

<p>A list containing the mapping between scale and guide.
</p>

<p>Other guides: 
<code><a href="guide_bins.html">guide_bins</a>()</code>,
<code><a href="guide_colourbar.html">guide_colourbar</a>()</code>,
<code><a href="guide_coloursteps.html">guide_coloursteps</a>()</code>,
<code><a href="guide_legend.html">guide_legend</a>()</code>
</p>

<h3>Examples</h3>

<pre>

# ggplot object

dat &lt;- data.frame(x = 1:5, y = 1:5, p = 1:5, q = factor(1:5),
 r = factor(1:5))
p &lt;- ggplot(dat, aes(x, y, colour = p, size = q, shape = r)) + geom_point()

# without guide specification
p

# Show colorbar guide for colour.
# All these examples below have a same effect.

p + guides(colour = "colorbar", size = "legend", shape = "legend")
p + guides(colour = guide_colorbar(), size = guide_legend(),
  shape = guide_legend())
p +

# Remove some guides
 p + guides(colour = "none")
 p + guides(colour = "colorbar",size = "none")

# Guides are integrated where possible

p + guides(colour = guide_legend("title"), size = guide_legend("title"),
  shape = guide_legend("title"))
# same as
g &lt;- guide_legend("title")
p + guides(colour = g, size = g, shape = g)

p + theme(legend.position = "bottom")

# position of guides

# Set order for multiple guides
ggplot(mpg, aes(displ, cty)) +
  geom_point(aes(size = hwy, colour = cyl, shape = drv)) +
  guides(
   colour = guide_colourbar(order = 1),
   shape = guide_legend(order = 2),
   size = guide_legend(order = 3)
 )
