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 "Raw temperature, salinity, and biogeochemical profile data acquired from APEX-EM floats deployed via U.Miami R/V Walton Smith in the northern Gulf of Mexico in May 2017. Period of record is for the first 10 days of operation during a cold front passage. The first day of record for each float ranges from May 2, 2017, to May 7, 2017. Technology for measuring subsurface ocean currents (including temperature and salinity) is available using the Autonomous Profiling Explorer floats with electromagnetic sensors (APEX-EM) recently developed by Teledyne Webb Research and the University of Washington. The float acquires temperature and salinity profiles using a Seabird sensor. This APEX-EM profiling float platform was equipped with chemical and bio-optical sensors: Aanderaa Optode sensor measuring dissolved oxygen, and the WET Labs ECO Puck sensor which combines measurement of chlorophyll fluorescence (proxy of phytoplankton abundance), measurement of backscatter (as proxy of particle concentration) and colored dissolved organic matter (CDOM) fluorescence (incl. fluorophoric oil components). Given the passage of a strong atmospheric front in May 2017, these data were used in an initial evaluation of the state-of-the-art float and its response to strong wind-driven currents. This float technology enables investigators to look more closely at the upper ocean response to strong forcing events that impacts biochemistry and hydrocarbon dispersion.  Sampling rates were changed by updating mission profiles from continuous to profiling modes between specific depths by changing the piston counts on the missions via  Iridium remote sensing when the float reaches the free surface.";

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").
