This paper takes the fire statistics of our country from 1950 to 2010 as an example, the data are as follows:

(0) Loading data

Data<-read.csv ("e:\\mydocument\\p\\data\\1950~2010 fire situation. csv")

X=t (Data[1])

Y=t (Data[2])

Z=t (Data[3])

W=t (Data[4])

Maxy=max (y)

Maxz=max (z)

Maxw=max (W)

(1) The number of fires, direct losses, casualties, respectively, according to the year of drawing

plot (x,y,type= "O", xlab= "year", ylab= "Fire (UP)", Ylim=c (0,maxy), col= "Red", main= "1950 to 2010 Fire Annual Statistics", Pch=c ()

plot (x,z,type= "O", xlab= "year", ylab= "economic loss (million)", Ylim=c (0,MAXZ), col= "Blue", main= "annual statistics of Fire economic losses from 1950 to 2010", Pch=c ( ))

Plot (x,w,type= "O", xlab= "year", ylab= "casualties", Ylim=c (0,MAXW), col= "Green", main= "annual statistics of Fire casualties from 1950 to 2010", Pch=c (17))

Note: x, y and y axes are shown in the graph, type sets the display type of the data in the graph, and the common ones are:

Type= "P" shows the data as a point in the graph;

Type= "L" in the graph data display as a line;

Type= "B" shows the data as points and connectors in the graph;

Type= "O" in the graph data points overlay online;

Type= "H" shows the data in the graph as a vertical line from point to X axis;

Type= "S" in the graph data display as a ladder diagram;

Type= "n" data is not displayed in the graph;

Xlab and Ylab respectively represent the x-axis and y-axis descriptions, Ylim to control the range of the y-axis, col as the color of the line, main as the main title of the graph, the PCH for the display of the number of points, the 1 to 25 integer and the symbol in the "":

(2) The number of fires, direct losses, casualties are drawn in a picture

> Plot (x,y,type= "O", xlab= "year", ylab= "", Ylim=c (0,maxy), col= "Red", main= "1950 to 2010 Fire Annual Statistics", Pch=c ()) #画火灾数曲线

> Lines (x,z,type= "O", col= "Blue", pch=c (+)) #追加经济损失曲线 > lines (x,w,type= "O", col= "green", pch=c (+)) #追加死伤人数曲线

(3) Add column

Legend ("TopLeft", C ("Fire (UP)", "economic loss (million)", "casualties"), Col=c ("Red", "Blue", "green"), pch=15:17)
