+ At the bottom of the generic plugin editor, clicking the arrow displays the
+ <dfn>Analysis Graph</dfn>.
+</p>
+<p>
+ This graph displays:
+</p>
+<ul>
+ <li>the <span style="background-color:black; color:white;">transfer function</span> in white,</li>
+ <li>the <span style="background-color:black; color:red;">phase response</span> in red (optionnal),</li>
+ <li>the <span style="background-color:black; color:green;">post effect spectrum</span> in green.</li>
+</ul>
+
+<p>
+ The <dfn>transfer function</dfn> plots the output amplitude of the plugin (considered
+ as a "black box") against its input amplitude, along the audio spectrum.
+</p>
+<p>
+ The <dfn>phase response</dfn>, that can be switched on or off using the
+ <kbd class="option">Show phase</kbd> checkbox, plots the phase of the
+ plugins output against its input phase, along the audio spectrum. The scale is
+ shown in <span style="background-color:black; color:yellow;">yellow</span> on
+ the right.
+</p>
+<p>
+ The green spectrum plots the <dfn>output signal spectrum</dfn>, after the plugin
+ (for tracks that have a signal on).
+</p>
+<p>
+ The <kbd class="menu">dB scale</kbd> selector in the bottom left allows to
+ change the vertical scale of the graphs.
