Things You Can Do With Your Graphs

Well, you can do anything you want with your graphs, of course. But some things you might not have considered are:

Web page authors can embed a graph of the latest data in a web page using HTML <img> tags.
Anyone can use ERDDAPs Slide Sorter to build a personal web page that displays graphs with the latest data (or other images or HTML content), each in its own, draggable slide.

    String summary 
"The Northwest Environmental Moorings program maintains
a number of buoys thoughout the Puget Sound region, taking regular profiling
casts with a winched CTD attached to a fixed mooring. These profiles measure
water pressure, water temperature, and conductivity. Depending on the mooring
configuration, additional instruments are added to take further measurements, 
which can include dissolved oxygen, nitrate concentrations, fluoroescence 
(a proxy measurement for chlorophyll concentrations), and turbidity.

This data has converted raw profiles into a gridded data product. Data from the downcast (i.e., from surface to maximum depth) is extracted, and used to grid each variable to pre-defined pressure levels. Quality control flags are used to improve gridded data quality. Bad data is removed during gridding, while suspect data is flagged. Using the pressure-gridded data, corresponding hydrostatic depths are calculated. From these hydrostatic depths, the data is then interpolated onto fixed depth levels.

This dataset has historical data, and adds new data shortly after any additional casts
have been performed. Data quality delay is usually less than 6 hrs.";

Using griddap to Request Data and Graphs from Gridded Datasets

griddap lets you request a data subset, graph, or map from a gridded dataset (for example, sea surface temperature data from a satellite), via a specially formed URL. griddap uses the OPeNDAP (external link)

Data Access Protocol (DAP) (external link)

and its projection constraints (external link)

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

(easy) You can get data by using the dataset's Data Access Form. It makes the URL for you.
(easy) You can make a graph or map by using the dataset's Make A Graph form. It makes the URL for you.
(not hard) You can bypass the forms and get the data or make a graph or map by generating the URL by hand or with a computer program or script.

griddap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/griddap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/griddap/jplMURSST41.htmlTable?analysed_sst[(2002-06-01T09:00:00Z)][(-89.99):1000:(89.99)][(-179.99):1000:(180.0)]
Thus, the query is often a data variable name (e.g., analysed_sst), followed by [(start):stride:(stop)] (or a shorter variation of that) for each of the variable's dimensions (for example, [time][latitude][longitude]).
