For most beginners, the first package that they use to get in touch with data visualization and storytelling is, naturally, Matplotlib: it is a Python 2D plotting library that enables users to make publication-quality figures. But, what might be even more convincing is the fact that other pac...

Visdom同时支持PyTorch的tensor和Numpy的ndarray两种数据结构,但不支持Python的int、float等类型,因此每次传入时都需先将数据转成ndarray或tensor。上述操作的参数一般不同,但有两个参数是绝大多数操作都具备的: win:用于指定pane的名字,如果不指定,visdom将自动分配一个新的pane。如果两次操作指定的win名字一样,新的...

Python >>> fig, ax = plt.subplots(nrows=2, ncols=2, figsize=(7, 7)) >>> ax1, ax2, ax3, ax4 = ax.flatten() # flatten a 2d NumPy array to 1d We could’ve also done this with ((ax1, ax2), (ax3, ax4)) = ax, but the first approach tends to be more flexible. To...
Plot a single point in a 3D space Let us begin by going through every step necessary to create a 3D plot in Python, with an example of plotting a point in 3D space. Step 1: Import the libraries import matplotlib.pyplot as plt
In [14]: data=np.arange(10)In [15]: dataOut[15]: array([0,1,2,3,4,5,6,7,8,9])In [16]: plt.plot(data) Figure 9.1: Simple line plot While libraries like seaborn and pandas's built-in plotting functions will deal with many of the mundane details of making plots, should you...
2D Line plotting with PlotPanel /PlotFrame PlotPanel and PlotFrame give the end-user the ability to: display x, y coordinates (left-click) zoom in on a particular region of the plot (left-drag) customize titles, labels, legend, color, linestyle, marker, and whether a grid is shown. A...
Matplotlib is a Python plotting library which produces quality figures in a variety of formats. We can create different types of plots like line chart, histograms, bar chart, pie chart, scatter chart, etc.pyLab is a module that belongs to the matplotlib which combines the numerical module ...
Example (run in ipython --gui=qt, or in the mayavi2 interactive shell, see Running mlab scripts for more info): import numpy from mayavi.mlab import * def test_barchart(): """ Demo the bar chart plot with a 2D array. """ s = np.abs(np.random.random((3, 3))) return barchar...
