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 
"Argo float vertical profiles from Coriolis Global Data Assembly Centres
(GDAC). Argo is an international collaboration that collects high-quality
temperature and salinity profiles from the upper 2000m of the ice-free
global ocean and currents from intermediate depths. The data come from
battery-powered autonomous floats that spend most of their life drifting
at depth where they are stabilised by being neutrally buoyant at the
\"parking depth\" pressure by having a density equal to the ambient pressure
and a compressibility that is less than that of sea water. At present there
are several models of profiling float used in Argo. All work in a similar
fashion but differ somewhat in their design characteristics. At typically
10-day intervals, the floats pump fluid into an external bladder and rise
to the surface over about 6 hours while measuring temperature and salinity.
Satellites or GPS determine the position of the floats when they surface,
and the floats transmit their data to the satellites. The bladder then
deflates and the float returns to its original density and sinks to drift
until the cycle is repeated. Floats are designed to make about 150 such
cycles.

Using tabledap to Request Data and Graphs from Tabular Datasets

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link)

Data Access Protocol (DAP) (external link)

and its selection 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 or Subset form. They make 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.

Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").
