    1. COI downloaded the file and this appears to be working... could you elaborate on your problem a little more? Pressing the pushbuttons clear the poles and zeros.

    2. COOnce I try to plot another pole or zero after the plane has been cleared from the graph it seems that different data is being plotted.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
