USGS Data Grapher

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

Note: I see that javascript is not currently enabled in your browser. That's okay -- the Data Grapher will work without javascript. I invite you to enable javascript for this page, however, because the Data Grapher interface utilizes javascript to clarify and simplify data input.

Step 1:

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

Step 2:

Choose a site from the drop-down list.

Measurements at this site are available here at 60 minute intervals. Some data are provisional and subject to revision. More data from this site may be available from NWIS-Web.

Step 3:

Choose a graph type.
Time Series
XY Plot

Step 4:

Choose the parameters to plot. For an XY plot, the 2nd parameter will be on the X axis.

1st Parameter:
	Apply a -day running average. Do not allow supersaturation.

2nd Parameter:
	Apply a -day running average. Do not allow supersaturation.

Step 5:

Choose starting and ending dates for the data in the graph.

Begin Date:	--	Include all data
End Date:	--	Include all data

Step 6:

Make the graph, or reset the form and try again.

Construction of the graph may take a minute or two.
