stackpoly {plotrix} | R Documentation |
Plot one or more columns of numeric values as the top edges of polygons instead of lines.
stackpoly(x,y=NULL,main="",xlab="",ylab="",xat=NA,xaxlab=NA, xlim=NA,ylim=NA,lty=1,border=NA,col=NA,staxx=FALSE,stack=FALSE, axis4=TRUE,...)
x |
A numeric data frame or matrix with the x values. If y is NULL, these will become the y values and the x positions will be the integers from 1 to dim(x)[1]. |
y |
The y values. |
main |
The title for the plot. |
xlab,ylab |
x and y axis labels for the plot. |
xat |
Where to put the optional xaxlabs. |
xaxlab |
Optional labels for the x positions. |
xlim |
Optional x limits. |
ylim |
Optional y limits. |
lty |
Line type for the polygon borders. |
border |
Color for the polygon borders. |
col |
Color to fill the polygons. |
staxx |
Whether to call staxlab to stagger the x axis labels. |
stack |
Whether to stack the successive values on top of each other. |
axis4 |
Whether to display the right ordinate on the plot. |

Additional arguments passed to plot. |
stackpoly is similar to a line plot with the area under the lines filled with color(s). Ideally, each successive set of y values is greater than the values in the previous set so that the polygons form a rising series of crests. If stack is TRUE, this is not a problem unless some values of x are negative.
If x or y is a vector, not a matrix or list, the values will be displayed as a "waterfall plot".
