IGB allows you to manipulate graph tracks in multiple ways, both by transforming an individual track or by combining two graph tracks in a mathematical way. Controls for transforming and combining graphs can be found in the Graph Adjuster tab. Any track that has been transformed or combined can be saved in one of three graphical formats: .bgr, .sgr or .gr (see File Formats for more details).
Transforming
By default, all graphs display in linear scale, but IGB allows you the option to transform a graph into other scales. Select the graph(s) and open the Graph Adjuster tab. Select the type of transformation you would like to perform from the pull-down menu labeled Transform, then click GO. The picture below includes all of the options available in IGB. However, many new Plug-ins add more transformation options which then populate this drop down list (see Plug-ins).
