描述----------Description----------

Details
详细信息----------Details----------
If the specification of layer is not numeric, it must specify a layer by a character expression of its datetime using the format "%Y-%m-%d %H". Leading zeros in the month, day, and hour components must be given (e.g. "2006-01-01 06")
如果layer规范是不是数字，则必须指定一个层，它的DateTime使用的格式"%Y-%m-%d %H"的字符表达。必须给予中的前导零，月，日，小时组件（例如"2006-01-01 06"）
If the data array has been aggregated in some way, the datetime dimension may no longer contain information on one or more temporal component: year, month, day, or hour. In this case, replace missing datetime componets with "XX" or "XXXX" (e.g. "XXXX-01-XX XX") when specifying a layer by a character expression of its datetime. Use dimnames to see the datetime dimension labels.
如果数据阵列已经以某种方式合并，日期时间维度可能不再包含一个或更多的时间组件：年，月，日，或一小时的信息。在这种情况下，替换丢失的日期时间COMPONETS与"XX"或"XXXX"（如："XXXX-01-XX XX"）指定一个层时，其日期时间的字符表达式。使用dimnames看到的日期时间标注标签。
If the geographical area to be plotted contains no landmass, the plot will exhibit a small unfilled border.
如果要绘制不包含大陆的GEO区域，该图将出现一个小的未填充的边界。
Most of the components of a plot produced by this function can be controlled by supplying a list of arguments to the embedded function that produces the particular component of the plot. For example, the text and size of the plot's title can be controlled by specifying a list of acceptable arguments to title.args. Similarly, the axes, map, and grid lines are controlled by specifying a list of acceptable arguements to axis.args, map.args, and grid.args, respectively. Through the argument image.plot.args the user can control the plotting of the filled contour surface, the color-bar legend, and the color-bar's title and axis labels. A list of arguments passed to interp.loess.args controls the interpolation of the filled-contour surface. See the examples below for a demonstration of how to apply these different arguments.
大部分此函数所产生的曲线图的组件可以通过以下来控制供给的参数列表，嵌入的函数，该函数产生的特定成分的图。例如，文本和大小的图的标题可以被控制通过指定title.args可接受的参数列表。同样，轴，图，网格线控制通过可接受的还要争拗axis.args，map.args和grid.args，分别指明一个列表。通过参数image.plot.args用户可以控制绘制填充的轮廓面，彩条传说，彩条的标题和轴标签。的参数传递interp.loess.args的一个列表控制的插值填充轮廓表面。下面的例子演示了如何应用这些不同的参数。
值----------Value----------
A plot is produced. No data are returned.
有一个图是。返回任何数据。
