When more variables are used and multiple lines are drawn, the grouping for lines is usually done by variable (this is seen in later examples).These are the variable mappings used here:time: x-axis total_bill: y
Example 4: Modify Fill Colors of Boxplots by Group Until now, we have changed the colors in a ggplot2 line and point graph. This example illustrates how to modify the colors of a boxplot graphic. For this, we can use the fill argument within the aesthetics of the ggplot function: ggpl...
(p8<-ggplot(data.frame(x = c(-6,6)), aes(x = x)) + stat_function(fun = dt, args = list(df = 18), geom = "line", linewidth = 0.4) + labs(tag = "p8", x = expression(t[0]), y = "Probability Density", caption = "R_ggplot绘图:基础技能(1)-绘制第二坐标轴", title ...
Now, we can use the geom_line & geom_point functions to draw a ggplot2 graph with lines and points: ggplot(data, aes(x, y))+# Draw ggplot2 plotgeom_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...
