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.

"This dataset contains results from Niskin bottle samples collected during CTD casts taken for nutrient concentration as well as the N isotopic composition of nitrate (NO3-). Corresponding CTD data measured at the same depths as the bottle samples are also included within the primary data file. CTD casts were carried out at fixed stations along the ship's track to calibrate float sensor results as well as document variability associated with mesoscale features.  

The associated cruise on the R/V Sally Ride, cruise SR2114, took place between 21 Dec 2021 and 21 Jan 2022 along a track between Costa Rica and San Diego, USA, transecting the oxygen-deficient zone (ODZ) of the Eastern Tropical North Pacific.  This cruise was in support of an NSF-funded project to develop an autonomous float array to study nitrogen loss (N-loss) processes in this region.";

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.
