A graphical user interface (GUI) is described for providing access to performance data for T1 or E1 communication lines. Data, such as error statistics, usage statistics, and burst measurements can be displayed graphically in a manner that can be easily assimilated by a user. The GUI is generated by a Java applet, to enable remote viewing of the data over the Internet or other network. A user can zoom in on a portion of a displayed plot of data by clicking with a cursor control device and dragging the cursor over a selected portion of the plot. The plot is automatically redisplayed with the selected portion enlarged. Alternatively, the user may click on a point on the graph to zoom in on a portion of the graph centered at the selected point. A first and second plot of data are displayed as a line graph and a filled region, respectively, to provide visual contrast between the plots.
