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 
"The Met Office Hadley Centre's sea ice and sea surface temperature (SST) data set, HadISST1, replaces the Global sea Ice and Sea Surface Temperature (GISST) data sets, and is a unique combination of monthly globally-complete fields of SST and sea ice concentration on a 1 degree latitude-longitude grid from 1870 to date.        
        
WARNING: 10 March 2016: A detailed analysis of HadISST (https://ir.library.oregonstate.edu/xmlui/handle/1957/58385) has identified a number of problems, some of which might limit the utility of the dataset for certain scientific applications, particularly where high resolution SST data or spatial gradients of SST are required. Thanks to Dudley Chelton and Craig Risien for bringing this to our attention and their detailed analysis.

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.
