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。

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.
