Natal Planets and Transiting Planets Tabs
One these 2 tabs are checkboxes for the planets that you want to show in the graph. The natal planets will show as straight horizontal lines whereas the transiting planets will show curved lines because their positions change during the period for which the graph plots positions.
On the Transiting Planets Tab it is a good idea to leave the Moon unchecked if the time span of the graph is greater than 2 months, especially so if you are using a dial of 90 degrees or so. This is because the lines would be drawn all over the graph obscuring the other phenomena because the Moon moves so fast. Check the Moon visible on the Transiting Tab and draw the graph to see what I mean.
