Set ggplot legend guides for each aesthetic when you have many legends.

Control the legend colors manually by specifying custom color values.Rename legend labels and change the order of items in a given legend.Modify the legend background color, key size and key width.Modify the font appearance (size, color / colour and face) of the legend title and text labels.Just specify the argument show.legend = FALSE in the given geometry. Hide legend for a specific geometry, say geom_text().

Example of R code: p + theme(legend.position = 'none'). Hide the entire legend to create a ggplot with no legend.Remove the legend title: p + theme(legend.title = element_blank()).Example of R code: p + guides(fill = guide_legend(reverse = TRUE)) for color of area fills (e.g.: box plot and bar graph) or p + guides(color = guide_legend(reverse = TRUE)) for point and line color (e.g.: scatter plot and line plot). It change the legend order for the specified aesthetic (fill, color, linetype, shape, size, etc). The easy way to reverse the order of legend items is to use the ggplot2 legend guides() function. You’ll will also learn how to put the legend inside the plot. We’ll show examples of how to move the legend to the bottom or to the top side of the plot. In the default setting of ggplot2, the legend is placed on the right of the plot. Change the legend title and text labels.This R graphics tutorial shows how to customize a ggplot legend.
