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

PrefaceA line chart is typically used to visualize the dependencies of two consecutive variables , where the horizontal axis is often the timeline.But the horizontal axis is not necessarily a continuous variable, it can be ordered discrete variable.draw a basic line chartThis example uses the following test data set:The drawing method is to first call the Ggplot function to select the dataset and indicate the horizontal axis in the AES parameter. Then

Introduction There is no doubt about the quality of the Ggplot2 package, but its drawing grammar is still a little difficult for beginners, Ggplot2: Data analysis and Graphic Art This book also introduces the basic philosophy and operation of Ggplot2 package, and the personal feeling examples are not rich enough, So the use of the package is still stuck at the dabbler level. One day, suddenly found a Ggplot2 package example book, exultation, English name is R Graphics Cookbook, Chinese version i

Draw a simple histogram Problem How to draw a histogram. Method Run the Geom_histogram () function and map a continuous variable to the parameter x (see Figure 6-1): Ggplot (Faithful, AES (x=waiting)) + Geom_histogram () Discuss The Geom_histogram () function requires only one column of the data box or a single data vector as a parameter. Taking the faithful dataset as an example, the dataset contains two columns of information describing the Old

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
