Graph Window Sizes
There are three different size options for graph windows... the windows that are created when you double-click on a subset to view a graph of the data within that subset. The graphs will differ in the amount of space that they require on the screen, and, perforce, the amount of information that each can display.
You can choose to have FlowJo open graphs in Normal, Medium or Large size by default. Each graph has the same data displayed. Each graph is resizeable to fit the space on your monitor.
The size of any newly-created graph window is determined by the preference that you have set. If you want to change the default size, open Preferences under the FlowJo menu item. Choose Graphs and under New Graph Windows choose your prefered size from the Size of new window drop down list. Click the save button and you're done.
