This article provides three different ways to call Ggplot in Python (IPython Notebook). In the big data age, data visualization is a very hot topic. Every BI vendor invests a lot of energy in the field of data visualization. With its powerful data visualization capabilities, Tableau has become a hot listed company in Silicon Valley. The theoretical basis of Tableau's data visualization is actually the Grammar of Graphic, which presents a syntax abstr

This article mainly introduces three methods to call ggplot in Python. ggplot, as a graphics library, is often used to create a visual view of data, you can refer to the following three methods to call ggplot in Python (IPython Notebook.

Introduction We often want to observe a batch of data distribution patterns, histograms, density map, box line map, violin map and point map are very good to achieve the form. Here, we briefly introduce histograms, density graphs and box-line graphs, which are more commonly used by us. Histogram A lot of people don't understand the difference between a bar chart and a histogram. The bar chart is mainly used to display classified data, that is, nominal data, each group is separated. And the histo

Today's meeting to discuss a half-day of their own research results, colleagues frowned, the first as if she did not understand, the second feeling in front of a bright, but do not know how to landing. Landed this thing, give time, I want to practice my analysis.Today I got a simple, bar chart.is a bar chart that is often played in Excel. Compare the BoxPlot and Ggplot, or ggplot more powerful, and make the

The Ggplot library used in Python in data analysis can be applied to drawData, for example, using data from the course VII of the InstituteData is: https://s3.amazonaws.com/content.udacity-data.com/courses/ud359/hr_year.csv Scatter plot: gp=pandas.read_csv (hr_year_csv) GG=ggplot (Gp,aes ('yearid','HR ') +geom_point (color='red') +ggtitle (U'total Hr by year ')The diagram shows2.

original dataframe in the variable will be used as an identifier, each identifier variable in one column, and the corresponding parameter is Measured.vars, not specified in the case, All variables except those specified as Id.vars are observed, and the names and values of the observed variables occupy one column, representing the variable and value variables in the result. The melt data can be called Ggplot for drawing, where the function separating

Tells the basic data structure in memory, array is good at finding the element, the list is good at finding the position, in order to adapt to the data different operation request, should use flexibly. 1. How the Memory WorksComputer memory is like a cupboard with many drawers.2. Arrays and Linked listsThe position of the element in the array is called the index element xx at index XXThe time complexity of the array and the different operations of the linked list3.
