USGS Data Grapher, Time Series with Percentiles

This is a data graphing utility that allows the user to build graphs of data from selected USGS stations with percentiles showing the range of historical data. Select the station, the parameter to plot, the starting and ending dates, and the years of interest for the graph. Then, click the button labeled "Make Graph."

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

 

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

Step 3: Choose the parameter to plot.

Parameter:
    Apply a -day running average.

Step 4: Choose starting and ending dates, and the years of interest, for the data in the graph.

Begin Date: -   Years:  
 
End Date: -
Shortcuts:
To select multiple years, hold down the Ctrl (Windows) or Command (Mac) key.

Step 6: Make the graph, or reset the form and try again.
