Reversing the Main Screen Chart
By clicking on the "Reverse Chart" button near the bottom right of the Main Reservation Screen, you can switch the view of the chart. The default way is to have the Dates across the screen, and the Room Names downward on the left side.
When viewing the other display, the Dates are downward on the left side, and the Room Names go across the screen.
The choice of which way you like to seen the screen presented is up to you.
