# Set Axis Breaks of ggplot2 Plot in R

In this article, we are going to see how to set axis break of ggplot2 plot in R Programming Language.

To add axis breaks in ggplot2 plots in R, we use scale_x_break() and scale_y_break() functions. These functions take a vector as a parameter that has breakpoints. If we need multiple breakpoints we can add those too.

Syntax:scale_x_continuous(breaks = <break-vec>)

scale_y_continuous(breaks = <break-vec>)

**Example 1: **Specify X-Axis Ticks in ggplot2 Plot

Here is a ggplot2 scatter plot with x-axis break using scale_x_continuous() function. This function has a breaks parameter that takes a vector as input which has all the points of axis break as vector points. So, here we can set the axis breaks point to a plot manually.

**Code:**

## R

`# Create sample data` `set.seed` `(5642) ` `sample_data <- ` `data.frame` `(x = ` `rnorm` `(1000), ` ` ` `y = ` `rnorm` `(1000))` `# Load ggplot2 and ggbreak` `library` `(` `"ggplot2"` `) ` `library` `(` `"ggbreak"` `) ` ` ` `# create plot with axis break` `ggplot` `(sample_data, ` `aes` `(x = x, y = y)) ` `+ ` `geom_point` `() + ` `scale_x_continuous` `(breaks = ` `c` `(-1,0, 1))` |

**Output:**

**Example 2: **Specify Y-Axis Ticks in ggplot2 Plot

Here is a ggplot2 scatter plot with y-axis break using the scale_y_continuous() function. This function has a breaks parameter that takes a vector as input which has all the points of y-axis break as vector points. So, here we can set the axis breaks point to a plot manually.

## R

`# Create sample data` `set.seed` `(5642) ` `sample_data <- ` `data.frame` `(x = ` `rnorm` `(1000), ` ` ` `y = ` `rnorm` `(1000))` `# Load ggplot2 and ggbreak` `library` `(` `"ggplot2"` `) ` `library` `(` `"ggbreak"` `) ` ` ` `# create plot with axis break` `ggplot` `(sample_data, ` `aes` `(x = x, y = y)) ` `+ ` `geom_point` `() + ` `scale_y_continuous` `(breaks = ` `c` `(-2, -1, 0, 1))` |

**Output:**

### Example 3: Specifying Sequence of Axis Ticks in ggplot2 Plot

To specify the sequence of axis ticks we use the seq function as a parameter to breaks the property of scale_x_continuous / scale_y_continuous instead of vector. Here instead of giving input as a vector, we give input as a sequence that has three points, the first is starting break, the second is ending break and the third one is break period between starting and ending break.

Syntax:plot+ scale_x_continuous(breaks = <seq-vec>) / scale_y_continuous(breaks = <seq-vec>)

**Code:**

## R

`# Create sample data` `set.seed` `(5642) ` `sample_data <- ` `data.frame` `(x = ` `rnorm` `(1000), ` ` ` `y = ` `rnorm` `(1000))` ` ` `# Load ggplot2 and ggbreak` `library` `(` `"ggplot2"` `) ` `library` `(` `"ggbreak"` `) ` ` ` `# create plot with axis break` `ggplot` `(sample_data, ` `aes` `(x = x, y = y)) ` `+ ` `geom_point` `() + ` `scale_x_continuous` `(breaks = ` `seq` `(-3, 4, 0.2))` |

**Output:**
