<p>You can create an original theme class yourself.
You can easily create new theme classes by extending the 'Theme' class and adding your own settings.
</p>
<p>Let's say that you like 'AquaTheme' but want to make some changes.
In 'AquaTheme', the y axis and y scale are not displayed. To change these settings and to display both, you can use the following. However, it can be time-consuming to add these lines to each graph individually.
</p>
<p>
</p><div class="hl-main"><table class="hl-table" width="100%"><tr><td class="hl-gutter" align="right" valign="top"><pre>1

</span><span class="hl-inlinetags">?></span></pre></td></tr></table></div><p>
</p>
<p>It may be easier to create a new theme based on the original but which has some different settings. Lets create 'MyAquaTheme'.
You should put the new theme class file in the 'Theme' folder, This is where all theme classes are kept.
</p>
<p>At first, create a file at Themes/MyAquaTheme.class.php.
The code for 'MyAquaTheme' class is the following.
</p>
<p>
</p><div class="hl-main"><table class="hl-table" width="100%"><tr><td class="hl-gutter" align="right" valign="top"><pre>1

</p>
<p>When redefining a method of parent class, please call the parent method.
In this way, all settings of the parent class method are applied and you can add the original settings.
Font, x axis, y axis colors etc are all defined as class properties. The following code shows how to change these settings.
