The option is provided for a title to be added automatically to the full charts, provided the program can find space for one.
To add a title to the full charts, or to prevent a title from being added, from the Options menu, click FullChart, then Add title.
If space cannot be found for a title, you may be able to create space for one by setting a margin at the top of the chart. Reducing the size of the font chosen for the title might also enable a title to be added. If this is not the case, then slightly increasing or decreasing the size of the font chosen for the chart itself (by choosing Fonts... from the Options menu) should enable space to be found for a title. Note that any figure between 3 and 20 can be specified for the font size for a chart.
You can also add a title of your own design to boxchart or full tree charts using the facility to insert text. See HowTo: Add pictures or text to a chart for instructions.
