decreasing=T), c(1,2,3)] input = melt(data, id='id') input$id = factor(input$id, levels = c(unique(input$id))) result = ggplot(input, aes(x=value, y=id)) + geom_line(aes(group = id)) + geom_point(aes(color = variable), size=4) + theme(legend....
ggplot(data, aes(x, y)) + # Draw ggplot2 plot geom_line() + geom_point()As shown in Figure 1, we created a line and point plot (i.e. a graph where the lines connect the points) using the ggplot2 package with the previously shown R syntax....
The above code is modified from:ggplot, drawing line between points across facetsggplot, drawing line between points across facets. And . There are two problems in this figure. First, only one vertical line was shown. It seems that moveToGrob only worked once.. Second, the shown line is n...
Also, I pretend to connect the points between NaN to see the tendency. This what I've been doing: 1st I tried the basic plotting ggplot2 ggplot(NDVI_sat_h_COR,aes(x=Date)) + geom_line(aes(y=meanNDVIU),colour="blue")+ geom_point(aes(y=meanNDVIU),colour="blue...
We make dumbbell plot by plotting points for each time point and connect them with a line for each country. In order to connect the points, we need specify which rows or countries need to be connected. We create a new variable that specifies the group corresponding to each country. library...
As you can see based on Table 1, our example data is a data frame composed of five observations and three columns with the names “group”, “sample”, and “responses”. Let’s assume that we want to create a ggplot2 barchart with a line on top, where the bars represent the sample...
geom: 图形的几何类型(geometry),这又是ggplot2的作图概念。ggplot2用几何类型表示图形类别,比如point表示散点图、line表示曲线图、bar表示柱形图等。 stat: 统计类型(statistics),这个更加特殊。直接将数据统计和图形结合,这是ggplot2强大和受欢迎的原因之一。

Basic line chart withggplot2andgeom_line() Aline chartorline graphdisplays the evolution of one or several numeric variables. Data points are usually connected by straight line segments. You read an extensive definitionhere. The input data frame requires at least 2 columns: ...
This post explains how to build a line chart that represents several groups with ggplot2. It provides several examples with explanation and reproducible code.
