How To Change Numbers In Plot R

In this article, nosotros are going to run into how to modify the centrality labels, legend, and plot labels using ggplot2 bar plot in R programming language.

For creating a simple bar plot we will utilise the function geom_bar( ).

Syntax: geom_bar(stat, fill up, colour, width)

Parameters :
stat : Set the stat parameter to place the mode.
fill : Represents color within the confined.
colour : Represents colour of outlines of the bars.
width : Represents width of the bars.

Dataset in utilise:

Let the states first visualize the graph equally it is so that the changes are apparent.

Example:

R

              ODI <-                            data.frame              (match=              c              (              "M-i"              ,              "M-2"              ,              "K-3"              ,              "M-4"              ),            
                            runs=              c              (67,37,74,x))            
              caput              (ODI)            
              library              (ggplot2)            
              perf <-              ggplot              (data=ODI,                            aes              (x=friction match, y=runs,fill=match))+            
                            geom_bar              (stat=              "identity"              )            
              perf            

Output:

Adding axis labels and main title in the plot

By default, R will apply the variables provided in the Information Frame every bit the labels of the axis. We tin modify them and change their advent hands. The functions which are used to change axis labels are :

xlab( ) : For the horizontal axis.
ylab( ) : For the vertical axis.
labs( ) : For both the axes simultaneously.
element_text( ) : The arguments of this function are :

Syntax:

element_text( family, face, colour, size, hjust, vjust, angle, margin)

element_blank( ): To make the labels NULL and remove them from the plot.

The argument hjust (Horizontal Adjust) or vjust (Vertical Adjust) is used to move the centrality labels. They take numbers in range [0,i] where :

hjust = 0 // Depicts left most corner of the centrality

hjust = 0.5 // Depicts middle of the axis

hjust = i // Depicts correct near corner of the axis

The keywords used are :

title : To add plot label.
subtitle : To add together subtitle in the plot.
caption : To add caption in the plot.
axis.championship.x : For horizontal axis.
axis.championship.y : For vertical centrality.

Example:

R

              library              (ggplot2)            
              ODI <-                            data.frame              (match=              c              (              "Thousand-1"              ,              "Thou-two"              ,              "Grand-3"              ,              "M-4"              ),            
                            runs=              c              (67,37,74,ten))            
              perf <-              ggplot              (data=ODI,                            aes              (x=match, y=runs,make full=friction match))+            
                            geom_bar              (stat=              "identity"              )            
              perf            
              ggp<-perf+              labs              (x=              "Matches"              ,y=              "Runs Scored"              ,            
                            title=              "Runs scored by Virat Kohli in ODI matches"              )            
              ggp            

Output:

A subtitle can also be included with the main title using labs() office and passing subtitle argument with the required subtitle.

For this theme() office is called with reference to which part of the plot has to exist modified. To these references, pass element_blank() without any argument.

Changing the Position of the legends

To change the position of the fable theme() role is called with legend.position as argument and to this argument, a required position is passed.

Syntax:

theme( legend.position = "Pos")

Parameter:

Pos : Left, Right, Peak, Lesser.
