Introduction We can also handle the axes of the graph, including x, y-axis swapping, setting axis range, tick mark modification and removal, and so on. In order to play the graphics, axis processing proficiency is indispensable. Axis Swap We use the Coord_flip () function to swap the axes.

Introduction A line chart is generally used to describe a variable of one-dimensional variables as a continuous variable, which is usually time. In other words, a line chart is best suited to describe changes in time series data. Of course, with the change of discrete variables is also possible, but this discrete variable must be ordered. Draw a line chart A basic line chart is relatively simple, as long as the AES in the Ggplot x,y data and Geom desi

Matplotlib is Python's most famous drawing library, this article has shared the use of matplotlib+numpy to draw a variety of methods of drawing examples, including fill chart, scatter plot (scatter plots),.

Matplotlibis an Open Source plotting the library designed to support interactive and publication quality plotting H A syntax familiar to Matlab users. Its interactive mode supports multiple windowing toolkits (CURRENTLY:GTK, Tkinter, Qt, and wxwindows) as OK as multiple Noninteractive backends (PDF, PostScript, SVG, Antigrain geometry, and Cairo). Plots can is embedded within GUI applications or for non-interactive uses without any available display

Nine algorithms for machine learning---regressionTransferred from: http://blog.csdn.net/xiaohai1232/article/details/59551240Regression analysis is to quantify the size of the dependent variable affected by the independent variable, to establish a linear regression equation or a nonlinear regression equation, so as to predict the dependent variable, or the interpretation of the dependent variable.The regression analysis process is as follows:① exploratory analysis, draw scatter
