ggplot(data = economics, aes(x = date, y = psavert))+ geom_line() Plot with multiple lines Well plot both ‘psavert’ and ‘uempmed’ on the same line chart. Solution 1: Make two calls to geom_line(): ggplot(economics, aes(x=date)) + geom_line(aes(y = psavert), color ...
level: level of confidence interval to use. Default value is 0.95 Regression line To add a regression line on a scatter plot, the functiongeom_smooth()is used in combination with the argumentmethod = lm.lmstands for linear model. p <- ggplot(cars, aes(speed, dist)) + geom_point()# ...
The notable point of this example is that we have used our own function to adjust the axis tick marks of our ggplot2 plot. This provides us with the possibility to manually specify the way how we want to display our axes, and we can specify the axes in the forefront of the creation ...
Note that, the functions scale_color_continuous() and scale_fill_continuous() can be used also to set gradient colors. Gradient between n colors # Scatter plot # Color points by the mpg variable sp3<-ggplot(mtcars, aes(x=wt, y=mpg, color=mpg)) + geom_point() sp3 # Gradient between...
Example 2: Create Multiple Grid Lines Using grid() Function In Example 2, I’ll illustrate how to draw a grid with multiple grid lines. For this, we simply have to increase the number of cells within the grid function: plot(1:10)# Create plotgrid(3,5)# Add grid ...
Add ablines withgeom_hline()andgeom_vline() An abline is a segment that goes from one chart extremity to the other.ggplot2offers thegeom_hline()andgeom_vline()functions that are dedicated to it. p+# horizontalgeom_hline(yintercept=25,color="orange",size=1)+# verticalgeom_vline(xin...
Do you want to make stunning data visualizations? Now you can — Here’s a complete guide to an amazing ggplot boxplot in R.
Creating this sort of small multiple chart is hard in most software. However, it’s rather easy to do in ggplot2 with facet_wrap. With that in mind, let’s look at how to create this sort of small multiple plot in ggplot2.
How to Label Outliers in Boxplots in ggplot2, This article offers a detailed illustration of how to name outliers in ggplot2 boxplots. Step 1: Construct the data frame. Create the following data frame first, which will include details on the 60 distinct basketball players who played for th...
lines(events2, type = "o", col = "blue") Output: 4. Add a legend to Line Graph We saw how to plot multiple lines in a single line chart. When there are more than two lines in the same line graph, it becomes clumsy to read. Legend plays a crucial factor there in order to und...
