USGS Two-Site Data Grapher

This is a data graphing utility that allows the user to build graphs of data from two USGS stations. Select the stations, the type of graph, the parameters to plot, and the starting and ending dates for the graph. Then, click the button labeled "Make Graph."

Data from the first site will be plotted against the Y axis on the left side of the graph. Data from the second site will be plotted against the Y axis on the right side of the graph, or against the X axis, depending on the type of graph you choose.

Step 1: [Optional] Choose a basin from the drop-down list.

 

Step 2: Choose the first site from the drop-down list.
