Because the next to do the seller background data vertical and horizontal revision, the data visualization of this piece of research and experience of the collation, with you to share the data visualization commonly used in five ways, hope to give you the development of ideas.

After listening to nividia's visualization computing technology recently, I feel quite deeply. If transactions or data can be displayed graphically, the most direct feeling can be given. The number of rows in the financial market is huge, and there are more and more types of transactions in the financial market (number of shares, number of funds, number of bonds, derivatives, etc ), if this data is displayed in a more direct way before the eyes of inv

This completes the same circular pop-up effect as the rubber band.In addition, the navigation bar out is also more abrupt, here also use animation, let it from left to right slowly stretched out:New Animate ({from: {x:x1, y:y1},to: {x:x2, Y:y2},delay:"point '" Bounceout ') function (value) {node.setcenterlocation (value.x, value.y);},}).

In the process of data visualization, we often need to display the data on the map based on the collected geographical location. For example, we want to map cities, aircraft routes, military bases, and so on. Generally, a Geographic Information Sys

First set up the basic environment, assuming there is already a Python operating environment. Then need to install some common basic library, such as NumPy, scipy for numerical calculation, pandas for data analysis, Matplotlib/bokeh/seaborn for data visualization. And then on demand to load the library of data acquisition, such as Tushare (http://pythonhosted.org/tushare/), Quandl (https://www.quandl.com/)
FrontierPython provides a number of modules for data visualization, including Matplotlib, Pygal. I refer to the online popular books "Python programming from the beginning to the actual combat", in the test and learning process encountered a few problems to solve, just write down this project experience, for the basic part of the Python is not detailed, mainly th
Python has a lot of visualization tools, this article only describes matplotlib.Matplotlib is a 2D drawing library that supports hard-copy and cross-system interactions that can be used in Python scripts, Ipython interactive environments, and Web applications. The project was launched by John Hunter in 2002 to build a MATLAB-style drawing interface for

Matplotlib is a common data-drawing package for Python, and its drawing is powerful, while Basemap is a sub-package of matplotlib, responsible for map drawing. This article briefly describes how to draw a wind map with this package. Here's how:
