In contrast to the dot plot which shows one probe(set)/gene per plot, the profile plot is used to visualize how the intensity values from multiple genes compare across all samples.

We will invoke a Profile Plot from a gene list child spreadsheet with genes on rows. 

The profile plot will be displayed in a new tab (Figure 2). Lines are probe(sets)/genes and columns are rows/samples from the parent spreadsheet. 

 

A basic profile plot will likely need customization. The plot configuration, properties, and control options are the same as in Dot Plot. We will illustrate a few modifications here. 

We can change the row labels to show each sample ID. 

We can add symbols to show which group each sample belongs to.

Symbols have now been added to each profile line plot (Figure 3).
