To plot a graph in R, you can use the `plot()`

function. This function allows you to create a variety of graphs to visualize your data.

In this article, we will explore how to create a graph in R using the `plot()`

function with examples.

**Method: Use plot() Function**

The `plot()`

function in R is used to create graphs. Here’s the syntax:

```
plot(x, y)
```

The following example shows how to plot a graph in R.

## Create a Graph Using plot() Function

Let’s see how we can plot a graph for two columns of a data frame using the `plot()`

function:

```
# Create data frame
df <- data.frame(Start_date=as.Date(c("2000-05-21","1998-03-28","2001-01-19","2003-04-27","2004-11-26","2008-11-25")),
Machine_name = c("Machine1","Machine2","Machine3","Machine4","Machine5","Machine6"),
Value = c(108,99,135,95,98,105),
Reading = c(110,97,91,89,80,85))
# Plot graph
plot(df$Value, df$Reading, main="Value vs Reading", xlab="Value", ylab="Reading", col="blue", pch=19)
```

Output: 👇️

In this example, the `plot()`

function creates a scatter plot of the `Value`

and `Reading`

columns from the data frame.

The `main`

parameter sets the title of the graph, `xlab`

and `ylab`

set the labels for the x and y axes, `col`

sets the color of the points, and `pch`

sets the type of points.
