您可以使用图表来做的事情

当然，你可以对图表做任何你想做的事情。但你可能没有考虑到以下几点：

• 网页作者可以使用 HTML <img> 标签在网页中嵌入最新数据的图表。
• 任何人都可以使用ERDDAP的幻灯片分类器来构建个人网页，该网页以自己的可拖动幻灯片形式显示包含最新数据（或其他图像或 HTML 内容）的图表。

    String summary 
"Since 1992, the Southwest Fisheries Science Center's Habitat and Groundfish
Ecology team has conducted visual surveys using submersible vehicles to quantify demersal
fish communities in deep seafloor habitats that are typically inaccessible to bottom trawls.
Data are collected from strip transects recorded with video and still cameras. To date, this
georeferenced dataset contains 460,000 individual fishes and 201 taxa, including 242,000
rockfishes (genus Sebastes) comprising 55 species, recorded from more than 2,000 transects
at depths 25-1,200 meters, primarily off California. Other data include estimated fish total
lengths, habitat, and in situ depth and temperature. The data have applications for a variety
of research topics, including ecology, distribution modeling, essential fish habitat, and stock
assessment. Videos from the surveys are available for download in mp4 format and
searchable by location, depth, species observed, and other factors.

This project was born out of a need to collect habitat-specific information on
rockfish abundance and ecology that cannot be obtained by traditional survey methods,
such as bottom trawling.";

使用 tabledap 从表格数据集请求数据和图表

tabledap允许您通过特殊格式的 URL 从表格数据集（例如浮标数据）中请求数据子集、图表或地图tabledap使用OPeNDAP 数据访问协议 (DAP ) 及其选择约束 。

URL 指定您想要的内容：数据集、图表或数据子集的描述以及响应的文件类型。

• （简单）您可以使用数据集的数据访问表单或子集表单获取数据。它们会为您生成 URL。
• （简单）您可以使用数据集的“制作图表”表单制作图表或地图。它会为您生成 URL。
• （不难）您可以绕过表格并获取数据，或者通过手动生成 URL 或使用计算机程序或脚本来制作图形或地图。

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.
