Cleveland dot plots are a great alternative to a simple bar chart, particularly if you have more than a few items. To color the data points with specific colors, we can use the argument palette.

Modifying colour on a plot is a useful way to enhance the presentation of data, often especially when a plot graphs more than two variables. R function: guides() Change the legend order in the situation where you have multiple legends (or multiple guides) generated by using multiple aesthetics (shape, color, size, fill, etc) in the plot.

This R tutorial describes how to create a box plot using R software and ggplot2 package.. Create a Dumbbell Plot using geom_point. Change manually the appearance (linetype, color and size) of ggplot lines by using, respectively, the function scale_linetype_manual (), scale_color_manual () and scale_size_manual (). Control the legend colors manually by specifying custom color values. We will now focus on the variation of same like diverging bar charts, lollipop charts and many more. In this example, we are using the values present in the cut column as color. The point geom is used to create scatterplots. A simplified format is : geom_boxplot(outlier.colour="black", outlier.shape=16, outlier.size=2, notch=FALSE) outlier.colour, outlier.shape, outlier.size: The color, the shape and the size for outlying points; notch: logical value. https://statisticsglobe.com/change-colors-in-ggplot2-line-plot-in-r In the previous chapters, we had a look on various types of charts which can be created using “ggplot2” package.

This R tutorial describes how to create a violin plot using R software and ggplot2 package.. violin plots are similar to box plots, except that they also show the kernel probability density of the data at different values.Typically, violin plots will include a marker for the median of the data and a box indicating the interquartile range, as in standard box plots. It can be used to compare one continuous and one categorical variable, or two categorical variables, but a variation like geom_jitter(), geom_count(), or geom_bin2d() is usually more appropriate.
