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."
To compare time series by month or year, try the Data Grapher by Year. To plot specialized XY plots from one site, use the XY Data Grapher. To plot data from two sites, use the Two-Site Data Grapher. To plot time series from three sites, use the Three-Site Data Grapher. To plot multiple graphs from a single site, try the Multiple-Parameter Data Grapher. For tables rather than graphs, go to the Data Tabler.
