The following code shows how to create a scatterplot in ggplot2 and decrease the point size by using the size argument: library(ggplot2) Example 2: Decrease Point Size in ggplot2 Notice that the points are much larger than the default size. #create scatterplot with increased point size The following code shows how to create a scatterplot in ggplot2 and increase the point size by using the size argument: library(ggplot2) The following examples show how to use each method in practice with the built-in mtcars dataset in R.įor reference, here’s what a ggplot2 scatterplot looks like using the default size: library(ggplot2)Įxample 1: Increase Point Size in ggplot2 The default size is 1.5 but you can decrease or increase this value to make the points smaller or larger. Traditionally, I've used base R to create these plots, but I've tried moving towards ggplot recently and find the inability to specify a 'scaffold' for bounding boxes of the figure to be the largest hurdle.You can use the size argument to change the size of points in a ggplot2 scatterplot: some_ggplot + in a publication or a web image slot with elements external to the plot that must line up with the plot). when filling those margins with axis labels.īasically, I have a fairly precise template to which each plot must conform (e.g. Ultimately, I'll have the same problem with the margins around the (data) plot area, e.g.
In base R plotting, this is accomplished with relatively straight-forward techniques like setting the oma and mar parameters (via par()), and then, given some fixed margins, one can go ahead and fill them up as best as possible.

In essence, I want the legend to be as compact as it's programmed to be, but have that legend's bounding box plus the dynamic padding to fill a specified width (or rectangle). I'd like the legend to still be its default size, but with dynamic padding. Thanks for the suggestion, but that simply makes the legend itself wider. I played around with the legend margin, but really I want to specify the legend 'minimal' bounding-box plus have the margin be dynamically padded such that the sum of the two is a fixed-width box.Īlternatively, I thought to specify the document width, then specify the plot and/or legend widths, left-justify those elements, then let there be 'free space' on the right side of the document, but I can't seem to find any existing set of options to let me easily do this. Looking at theme I couldn't find an option to specify the legend box width. In essence, I have a fixed 'template' for the plot, such that some external elements outside the plot's boundaries are 'lined-up' correctly. The various plots must fit into a specified publication slot, with a specified width for the legend, and the plots must be made separately (so faceting to guarantee identical legend widths across the plots isn't possible). I want the legend box to be the same width for each plot, but ggplot dynamically sizes the legend box based on the legend name, key values, etc.
Using ggplot, I have multiple plots, each of which has a legend box.
