fig, ax = plt.subplots() contours = ax.contour(x, y, z, levels=np.linspace(-0.02, 0.02, num=1000), colors='black', linestyles='-') plt.show() but the problem is that this takes quite a while and the final product is not particularly neat. python numpy ...

I am using python 2.7.3 with matplotlib 1.1.1 on Windows 7. I propose to generate a pseudo colorbar as follows (see comments for explanations): importmatplotlib.pyplotaspltimportnumpyasnpfrommatplotlib.colorsimportLogNormimportmatplotlib.gridspecasgridspec delta =0.025x = y = np.a...
Matplotlib - Contour Plots - A contour plot, also known as a contour map or a level plot, is a graphical representation of a three-dimensional surface on a two-dimensional plane.
The colors used in plotting a 3D surface using plot_surface() and the corresponding contours generated using contour() or contourf() should match, but they don't. Here's a minimal example demonstrating the issue from mpl_toolkits.mplot3d import axes3d import matplotlib.pyplot as plt from mat...
triangulation:这个参数是一个matplotlib.tri.Triangulation对象。 Z:这个参数是等高线的值数组,在三角剖分中每个点一个值。 **kwargs:这个参数是Text属性,用于控制标签的外观。 所有剩余的参数和kwargs与matplotlib.pyplot相同。pcolor()。 返回2个Line2D的列表,包含以下内容: 画出三角形边的线。 标记为三角形节点 ...

与matplotlib.pyplot的创建方式的区别,投影可以直接在创建画板时设置。 axwidth :调节画板的清晰度,可能,没怎么用过 refwidth: 各子图的长宽比 suptitle:各子图的总标题 proj='cyl', 设置为等间距投影 proj_kw={'lon_0': 180}, lonlim=(100, 200), ...
