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 "This is a test mission for the Northwest Passage Project. This glider will be deployed in the southern Mid-Atlantic Bight. The goal of the mission is to conduct CTD and DO Optode cross-calibration with a recently calibrated MARACOOS glider Sylvia in the MARACOOS domain. It will provide additional hydrographic data in the Mid-Atlantic region even though its CTD has not been recently calibrated. The glider is scheduled to be deployed on Tuesday, May 1, 2018 and recovered on Monday May 14, 2018. The glider will be deployed near the 35 m isobath at mid-shelf off Wachepreague VA and fly offshore toward Washington Canyon. It will conduct virtual mooring profiling flight at the head of Washington Canyon down to 350 m for about a week, then head back inshore toward Wachepreague VA for recovery.";

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").
For details, see the tabledap Documentation.
