# Changing Styles of Lines

You can set the style of plotting for both function and data plots. To
change the default style for functions, use the **set function
style** command, and to set the default for data plots, use the
**set data style** command.
**set function style ***line-style*
**set data style ***line-style*

To see the current line style, type the following:
**show function style****show data style**

You can also add the **with** keywork to **plot** and
**splot** commands. For example,
**plot sin(x) with boxes****plot "turkey.dat" with
impulses**

You can also specify differant line style when overlaying differant
plots, for instance,
**plot sin(x) with boxes, cos(x) with steps**

This produces the following graph:

# Different Line Styles

The following line styles are available for 2D function and data
plots:
** `lines`, `points`, `linespoints`, `impulses`, `dots`, `steps`,
`errorbars`, `boxes`, and `boxerrorbars`**

## Lines

This is the default plotting style. It connects the data points with a
line. Note that if you are doing a Data plot, blanks lines in the data
file will cause gnuplot to not connect the data points with a line.

## Points

The Points Style puts a point at each data point.

## LinesPoints

This is a combiniation of the two style - Lines and Points.
**plot sin(x) with linespoints**

## Impulses

The impulses style draws lines from the x-axis to each point.

## Dots

The Dots style places very small dots for each data point. This would
be useful for scatterplots with large amounts of data.
## Steps

This connects consecutive points with two perpindicular line segments.

## Error Bars

GnuPlot can add error bars, which suggest a range of data, only for 2D
data plots. They use the third columnd in the file as the "delta"
value. For more information, see **help plot errorbars**.
**plot "login.dat" with errorbars**

There is also a BoxErrorBars style that combines this style with boxes.

## Boxes

This draws boxes from the xaxis to the the points.

## 3D Plots

The only line styles available for 3D plots are "lines",
"linespoints", "impulses", and "dots".

For more information on line styles, see **help set style**
