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 overarching goal of this project was sustained sampling of upper ocean hydrography to resolve the seasonal-to-interannual modulation of meso- and fine-scale thermohaline structure. To achieve this goal, Spray underwater gliders made repeated occupations of a 1300-km meridional section northward from Hawaii to 34.5N along 158W. The data set includes 1014 glider-days, covering 22566 km over ground, 22720 km through water, with 4641 dives.";

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
Data Access Protocol (DAP) and its
selection constraints.
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").
For details, see the tabledap Documentation.
