1.) WIthin the dashboard dashboard view, you would need to have all of the graph views that you wish to be currently defined within the analysis view. The dashboard view only utilizes the predefined analysis reports to populate the dashboard views. You would need to define a separate report for each of your desire4d views and then create the dashboard view by selecting these different views during its creation (as they will default to whatever graph style the analysis view is utilizing).
2.) The way that you would set the dashboard analysis view report as a table view is within the ''Set Graph View'' setting on the right hand side menu above where the graph is displayed, you would select it and then select the Default layout and change it to be whatever you would like the default display to be (i.e., graph, pie chart, data grid). This then changes the way that report would be displayed.
I hope this helps.
