The Fit to Window option allows the data columns in a table to automatically expand or shrink to fit the window each time you resize it.
When Fit to Window is disabled, the data columns must be sized manually.
To enable or disable the fit to window option
Right-click the top border of the visualization and click Fit to Window.
When enabled, an X appears to the left of Fit to Window.
To resize data columns manually
Click the line dividing any two data columns (in the top-axis region) and drag to the desired width.
