![]() I've tried a few things and they all ended up being horrendously long, so I'm looking for the smallest expression and ideally would like to have the dates on the x-axis (which are not there in the plot below). For example, in the table below, FFFFFF is white and 990000. I'm learning to use ggplot2 and am looking for the smallest ggplot2 code that reproduces the base::plot result below. The value for each ranges from 00 to FF in hexadecimal (base-16) notation, which is equivalent to 0 and 255 in base-10. ![]() The first two digits are the level of red, the next two green, and the last two blue. Outside of aes(): library ( gcookbook ) # Load gcookbook for the tg data set # Save the position_dodge specification because we'll use it multiple times pd <- position_dodge ( 0. Colors can specified as a hexadecimal RGB triplet, such as '0066CC'. To set a single constant shape or size forĪll the points, as in Figure 4-16, specify shape or size You may want to use a different palette, using scale_colour_brewer() The default colors are not very appealing, so Points for each group by mapping variables to aesthetic properties of ![]() Lines will be drawn on top of the points.įor multiple lines, we saw in Recipe 4.3 how to draw differently colored ![]() Points after the lines, so that they are drawn on top. If the points and lines have different colors, you should specify the ![]()
