All Visualizations graphs can be edited and created once subscription is purchased. 

Creating your own Graphs for your Gantter Project with Tableau. 

When in the Visualization tab on your Left Toolbar, you will find a green “Manage Visualization” button to create new graphs if you do not see a graph on Gantter’s already made templates. Please note that you will need to be a paid subscription owner to access this feature. 

From here you will be able to “Add New Viz” or “Edit Viz.”  Creating your graph is as easy as selecting the “Data” you want to view from the left side of the screen, and dragging to Columns or Rows.
