There are three zooming modes: Fixed, Fit and Auto Fit.
Fixed: The zoom ratio does not change when the source changes or the window size changes.
Fit: The graph is scaled to align to the border of the visible view area.
Auto Fit: When the view area is big enough to contain a 100% sized graph, the graph will be set a zoom ratio of
100%, otherwise the graph is scaled to fit into the view area.
To export the generated graph, click the “Export” button on the top right corner.
