The "Calculated Charts" listbox (also referred to as the "Calculated Charts" list) on the Main Screen contains a list of all the charts that are currently available for immediate use in Solar Fire. This is not all the charts that exist in Solar Fire, rather it the charts that have been "calculated" and are therefore now able to be used in the current session. This list of charts is the CENTRAL point for nearly all operations in Solar Fire as most (although not all) of the things you can do in Solar Fire involve a chart of one kind or another. And to use a chart it needs to be in the list of "Calculated Charts".
You can add to this list by casting new charts, opening saved charts, generating subsidiary charts using various options in the "Chart" menu, or copying a chart that is already in the "Calculated Charts" list .
You can select any number of charts in this list by holding down Ctrl or Shift keys while clicking the left mouse button. (The "Current Chart Preview" panel will always display the details of the most recently selected chart - the "current" chart.) To select charts all adjacent to each other (next to each other) in the list click on the first chart, then hold the Shift key down and click on the last chart you want, then release the Shift key. To select charts not adjacent in the list click on the first chart, then hold the Ctrl key down and click on each chart you want in the selection, then release the Ctrl key. Use the Ctrl in the same manner to unselect any chart from a selection.
Some functions in Solar Fire will allow all your selected charts to be processed, whilst others can work only with the single current chart. For example, when you choose View / Current Chart or Chart / Save to File, all the selected charts will be processed. However, when you choose Interps / View, only the current chart is used.
You can also delete charts from this list if you wish. To delete many at the same time first select all the charts, as described above.
