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。

The hybrid coordinate is one that is isopycnal in the open, stratified ocean, but smoothly reverts to a terrain-following coordinate in shallow coastal regions, and to z-level coordinates in the mixed layer and/or unstratified seas. The hybrid coordinate extends the geographic range of applicability of traditional isopycnic coordinate circulation models (the basis of the present hybrid code), such as the Miami Isopycnic Coordinate Ocean Model (MICOM) and the Navy Layered Ocean Model (NLOM), toward shallow coastal seas and unstratified parts of the world ocean.";

使用 griddap 从网格数据集请求数据和图表

griddap允许您通过特殊格式的 URL 从网格数据集中请求数据子集、图表或地图（例如，来自卫星的海面温度数据）。griddap 使用OPeNDAP (external link)

数据访问协议 (DAP ) (external link)

及其投影约束

。

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获取数据。它会为您生成 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。

griddap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/griddap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/griddap/jplMURSST41.htmlTable?analysed_sst[(2002-06-01T09:00:00Z)][(-89.99):1000:(89.99)][(-179.99):1000:(180.0)]
Thus, the query is often a data variable name (e.g., analysed_sst), followed by [(start):stride:(stop)] (or a shorter variation of that) for each of the variable's dimensions (for example, [time][latitude][longitude]).

For details, see the griddap Documentation.
