<h4>splitChannelOptions</h4>

<p>
|
|
<code>overlay</code> - boolean - This determines whether channels are drawn on top of each other.
|
|
</p>
|
|
<p>
|
|
<code>channelColors</code> - object - Pass this to set colors for each channel. If the channel index is not found on the object, colors will default to the top level color params.
|
|
</p>
|
|
<p>
|
|
<code>filterChannels</code> - array - Array of channel numbers. Channels included in the array will not be drawn.
|
|
</p>
|
|
<p>
|
|
<code>relativeNormalization</code> - boolean - When <code>normalize</code> and <code>splitChannels</code> are both true the channels will be normalized individually or proportionally to each other. Defaults to <code>false</code> (each channel will be normalized in isolation).
