set the norm limits for image scaling; if vmin is a length2 sequence, interpret it as (vmin, vmax) which is used to support setp ACCEPTS: a length 2 sequence of floats; may be overridden in methods that have vmin and vmax kwargs. set_cmap(self, cmap)[source] set the colormap for...
matplotlib 介绍 matplotlib 是一个Python的 2D绘图库,用于数据可视化。它可以函数的方式操作各个绘图命令(类似Matlab软件,Matplotlib名字的含义就是Matlab风格的绘图库),也可以以面向对象的方式。 它有以下优点: 绘图质量高,可绘制出版物质量级别的图形。 代码够简单,易于理解和扩展,使绘图变得轻松。 兼容Tex 文本,可编...

(instead of 1). If density is True, the weights are normalized, so that the integral of the density over the range remains 1. This parameter can be used to draw a histogram of data that has already been binned,e.g. using numpy.histogram (by treating each bin as a single point with...
ImportError: DLL load failed: %1 is not a valid Win32 application. It looks like there is something broken with the TK installation which should be part of your python installation and which matplotlib uses for the TK backend. What happens if you do?
其中从TICKLEFT开始的几个英文单词,不知道怎么用。 For backward compatibility, the form (verts, 0) is also accepted, but it is equivalent to justvertsfor giving a raw set of vertices that define the shape. 其它的参数暂时不去分析,以后用到时再说。
A format string consists of a part for color, marker and line:: fmt = '[marker][line][color]' Each of them is optional. If not provided, the value from the style cycle is used. Exception: If ``line`` is given, but no ``marker``, ...
