<div><h2 id="ex:australia">1.11.2 Text Labels</h2>
<p>Text labels may be placed on plots using the <tt class="tt">set label</tt> command<a name="a0000000820" id="a0000000820"></a>. As with all textual labels in PyXPlot, these are rendered in L<sup style="font-variant:small-caps; margin-left:-0.3em">a</sup>T<sub style="text-transform:uppercase; margin-left:-0.2em">e</sub>X: </p><pre>
set label 1 'Hello World' at 0,0
</pre><p>As in the previous section, the number <tt class="tt">1</tt> is a reference number, which allows the label to be removed by either of the following two commands: </p><pre>
set nolabel 1
unset label 1
</pre><p>The positional coordinates for the text label, placed after the <tt class="tt">at</tt> keyword, can be specified in any of the coordinate systems described for arrows above. As above, either two or three coordinates may be supplied. A rotation angle may optionally be specified after the keyword <tt class="tt">rotate</tt><a name="a0000000821" id="a0000000821"></a>, to rotate text counter-clockwise by a given angle, measured in degrees. For example, the following would produce upward-running text: </p><pre>
set label 1 'Hello World' at axis3 3.0, axis4 2.7 rotate 90
</pre><p>A colour can also be specified, if desired, using the <tt class="tt">with colour</tt> modifier. For example, the following would produce a green label at the origin: </p><pre>
set label 2 'This label is green' at 0, 0 with colour green
</pre><p><a name="a0000000822" id="a0000000822"></a><a name="a0000000823" id="a0000000823"></a> The size of the text in such labels can be set globally using the <tt class="tt">set fontsize</tt> command<a name="a0000000824" id="a0000000824"></a>. This applies not only to the <tt class="tt">set label</tt> command, but also to plot titles, axis labels, keys, etc. The value supplied should be a multiplicative factor greater than zero; a value of <tt class="tt">2</tt> would cause text to be rendered at twice its normal size, and a value of <tt class="tt">0.5</tt> would cause text to be rendered at half its normal size. </p><p><a name="a0000000825" id="a0000000825"></a><a name="a0000000826" id="a0000000826"></a> The <tt class="tt">set textcolour</tt> command<a name="a0000000827" id="a0000000827"></a> can be used to globally set the colour of all text output, and applies to all of the text that the <tt class="tt">set fontsize</tt> command does. It is especially useful when producing plots to be embedded in presentation slideshows, where bright text on a dark background may be desired. It should be followed either by an integer, to set a colour from the present palette, or by a colour name. A list of the recognised colour names can be found in Section <a href="sec-colour_names.html">8.4</a>. For example: </p><pre>
set textcolour 2
set textcolour blue
</pre><p><a name="a0000000828" id="a0000000828"></a><a name="a0000000829" id="a0000000829"></a>By default, each label’s specified position corresponds to its bottom left corner. This alignment may be changed with the <tt class="tt">set texthalign</tt><a name="a0000000830" id="a0000000830"></a> and <tt class="tt">set textvalign</tt><a name="a0000000831" id="a0000000831"></a> commands. The former takes the options <tt class="tt">left</tt><a name="a0000000832" id="a0000000832"></a>, <tt class="tt">centre</tt><a name="a0000000833" id="a0000000833"></a> or <tt class="tt">right</tt><a name="a0000000834" id="a0000000834"></a>, and the latter takes the options <tt class="tt">bottom</tt><a name="a0000000835" id="a0000000835"></a>, <tt class="tt">centre</tt><a name="a0000000836" id="a0000000836"></a> or <tt class="tt">top</tt><a name="a0000000837" id="a0000000837"></a>, for example: </p><pre>
set texthalign right
set textvalign top
