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."

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

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.

Ball Bay Met Station [BLB MET] (422341122003800)
Parameter	Begin Date	Last Approved Date	Last Reading
Air Temperature	Oct-21-2005 13:00	Nov-17-2010 11:00	Nov-17-2010 11:00
Relative Humidity	Oct-21-2005 13:00	Nov-17-2010 11:00	Nov-17-2010 11:00
Wind Speed	Jun-01-2005 16:15	Nov-17-2010 11:00	Nov-17-2010 11:00
Wind Direction	Jun-01-2005 17:15	Nov-17-2010 11:00	Nov-17-2010 11:00
Measurements at this site are available here at 15 minute intervals. Some data are provisional and subject to revision. More data from this site may be available from NWIS-Web.

Step 3:

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

Step 4:

Choose the second site from the drop-down list.

Step 5:

Choose a graph type.
Time Series
XY Plot

Step 6:

Choose the parameters to plot. For an XY plot, the parameter from the second site will be on the X axis.

Ball Bay Met Station [BLB MET] (422341122003800)
1st Site's Parameter:
	Apply a -day running average. Do not allow supersaturation.

Ball Bay Met Station [BLB MET] (422341122003800)
2nd Site's Parameter:
	Apply a -day running average. Do not allow supersaturation.

The Vector Mean statistic is for wind-speed and wind-direction data only.
The Unit-Vector Mean statistic is for wind-direction data only.

Step 7:

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

Begin Date:	--	Include all data Include only the last days
End Date:	--
Month-Day shortcuts:

Step 8:

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

Construction of the graph may take a minute or two.
