different effects of the graph, such as color, coordinate name, whether 100% accumulation and so on. The specific parameter settings can be referenced as follows:If we adjust the color: 1 plot.area (grp.dat,col=c (' Red ', ' lightgreen ', ' Purple ')) the results are as follows:Let's take a look at how to draw an area chart with Ggplot2. Before drawing, first we need to convert our data format, we need to summarize multiple columns in

Ggplot2 scale correlation settings-coordinate transformationThere are several forms of axis conversion in R, including logarithmic conversion, square root conversion, and pre-and post-scale exchange of coordinates.The functions used are:SCALE_X_LOG10 (...) SCALE_Y_LOG10 (...) Scale_x_sqrt (...) Scale_y_sqrt (...) Scale_x_reverse (...) Scale_y_reverse (...) The above functions are actually based on scale_x_continuous (name = Waiver (), breaks = Waiver
