When you click on the Reports button on the Home tab, you are given the option of various types of reports.  Select the type of report by simply clicking the one you want. 

The reports listed under the separator are fixed and will always view the data in one way.  The reports listed above the separator are dynamic and may be changed.  These are the reports that you have the most control over how you want to view the data.  For example, use these graphs to plot the desired data as well as displaying summaries under the graph, customize your date range, or your tanks of interest, to choose the plotted data.  For titration results or chemical additions, you can also filter by chemical.
