We will use the PlantGrowth data set to depict an example of R dot plot, the above dotchart() function takes up numeric vector as first argument and plots the red dots with labels and title. The main difference is that the dot plot in R displays the index (each category) in the vertical axis and the corresponding value in the horizontal axis, so you can see the value of each observation following a horizontal line from the label. If TRUE, create a multi-panel plot by combining the plot of y variables. Note that there are several types of dot charts, like the classical, the Cleveland’s version and Dumbbell dot plots. In our example, it could be interesting to represent the sold and expected variables together, to analyze the difference between the expected and actual sales. x: either a vector or matrix of numeric values (NAs are allowed).If x is a matrix the overall plot consists of juxtaposed dotplots for each row. As there is not any base R graphics alternative that provides this functionality, we have developed the dumbbell function, which works with grouped and ungrouped data. So the output will be, Suppose if we want to create the different dot plots for different group of the same data set, how to do that?
