Kaggle users have created nearly 30,000 kernels on our open data science platform so far which represents an impressive and growing amount of reproducible knowledge. e matplotlib scatter or hexbin or seaborn kdeplot). Seaborn is a data visualization library used for data science that provides a high-level interface for drawing graphs. In terms of the interface, pygal is kind of the opposite of matplotlib in that it's a high level charting library — it makes it very easy to draw a plot, but makes it harder to have complete control over the way it looks or to make custom graphics. Specifically, NumPy and Pandas are used for array manipulations, while Matplotlib and Seaborn generate the graphical visualizations. 95+ chart types, 1400+ maps and 20+ business dashboards with pre-built themes for any business use-case. 水平和垂直误差线可以提供给 plot() 的 xerr 和 yerr 关键字参数。 可以使用各种格式指定错误值。 As a DataFrame or dict of errors with column names matching the columns attribute of the plotting DataFrame or matching the name attribute.

The types of graphs that can be produced in Seaborn include swarm plots, bar charts, box plots, histogram, and violin plots. Please note that sparse=False, copy=False will likely return non-contiguous arrays. What this suggests should be obvious: some terms are more common than others. jointplot returns a Seaborn grid object. Seaborn also has tight integration with the PyData stack. Color saturation for the hexbins shows the density of points within each bin, with darker bins showing more points. This makes it tricky to see the differences between slices, especially when you try to compare multiple Pie Charts together. It aggregates the Values in hexagonal bins and color codes them by number. 即：假如有x个样本,如果我们用Gaussian Kernel Density(就是常说的正态分布啦),对每一个样本,我们都认为这个样本处在一个正态分布的峰值位置,(因为我们已经发现这个样本了). jointplot().
