If I am understanding correct, you want to manually drag the colorbar to some desired location on the generated figure.
To achieve this, open the 'Edit' drop-down menu from the toolbar present in the generated figure. Thereafter select the 'Axes Properties', the figure objects open in an editable view. Here you can click and drag both your plot and the colorbar.
There are also various command line options present which can position the colorbar as desired. Details about the same can be found under the 'Position' sub-section, at the following documentation link:
