IGB can display graphs in several file formats, developed at Affymetrix or elsewhere. All file names must include the file name extension, such as "'.sgr"'. Compressed files must include the graph type extension AND the compression extension, such as "mygraph.sgr.zip". For the list of all file formats IGB supports, see File Formats.
Note: Set Species and Genome Version before loading graph files, as you would for annotation files. Graph files in some formats (notably .gr) do not contain information about which genomes and chromosomes they correspond to, so be sure to set Species and Genome Version before or as part of loading these files. These may be loaded and displayed alongside annotations on any chromosome, but the data may have no meaning if compared to the a chromosome it was not designed for. i.e., to use a .gr file, you must first load the proper organism, genome AND chromosome prior to loading the .gr file

Hidden graphs can be restored by right clicking in ANY track label and using the Show function. To hide one or more tracks, select the graph tracks or use the Select All button in the Graph Adjuster panel, right click and select Hide. Alternatively, use the Data Management Table to hide and show.
Delete graphs to permanently remove them from the viewer and from memory. To delete graphs created in IGB, select the graph or graphs, and click the Delete button. Loaded graphs can be delete the same way or, just click the trashcan icon next to the graph file name in the Data Access panel, as you would for an annotation trackGraph button in Graphs tab, use the Toolbar shortcut Delete Selected Track or use the red X icon in the Data Access > Data Management Table.
Saving graph tracks
IGB allows you to save individual graph tracks for later use or sharing. This is especially important for graph tracks made in IGB, either through manipulation of your graphs or after using one of IGB's create graph functions. Select the graph track, then in the Graph Adjuster tab, click the Save Selected... button. You will be offered to save the file in .wig or .egr format. Details about these formats is found in File FormatsSee Saving and Sharing Data.
