The easiest way I find to do this is to first place a Horizontal Container on the dashboard. Then, place one of your worksheets within it. Then, drag a Vertical Container to the far right of the first container and place a worksheet in it. Finally, choose one more Vertical Container and drag it below the 2nd container and place the 3rd worksheet within it. Then, change the sizes of the worksheets within each container to get them to fill the whole space.
Hope this helps a little bit!
Unfortunately, when I put the 3rd vertical container, it won't stay on the right. Instead, it occupies the whole bottom from left to right. See snapshot with that I end up with.
P.S I can usually achieve the layout only if I place a container within a container which I don't like to do because the borders would not be distinct for each of the views.
