SDS:Preselection registration subject time.php

This allows the user to create graphs for each subject, displaying the total number of course requests changes against time. In addition, it will also show how course registrations in each subject change with time.

You can select as many subjects as you like using the first multiselect. Click on Select subjects to see their graphs.

You can also select one or more departments using the second multiselect. Click Select subjects by department to see their graphs.

Once the graphs are drawn, each line can be hidden or shown by clicking on its name in the legend at the top.
