By default, the Start Collection button 
overwrites collected data with data from the next run. To preserve each run, you can store it as a data set. After collecting multiple data sets, you can superimpose any combination of them on the Graph View.
Important: Stored data sets are lost if you close the document without saving it. If you want stored data to be available later, make sure to save the document.
