# plerry(3plplot)

Draw error bars in the y direction

## NAME

**plerry** - Draw error bars in the y direction

## SYNOPSIS

**plerry**(*n*, *x*, *ymin*, *ymax*)

## DESCRIPTION

Draws a set of *n* error bars in the y direction, the i'th error bar extending from *ymin*\[i\] to *ymax*\[i\] at x coordinate *x*\[i\].  The terminals of the error bars are of length equal to the minor tick length (settable using [**plsmin**(3plplot)](/plsmin/3plplot.md)).

Redacted form: General: **plerry(x, ymin, ymax)**

This function is used in example 29.

## ARGUMENTS

- *n* (**PLINT**(3plplot), input)

  Number of error bars to draw.

- *x* (**PLFLT\_VECTOR**(3plplot), input)

  A vector containing the x coordinates of the error bars.

- *ymin* (**PLFLT\_VECTOR**(3plplot), input)

  A vector containing the y coordinates of the lower endpoints of the error bars.

- *ymax* (**PLFLT\_VECTOR**(3plplot), input)

  A vector containing the y coordinates of the upper endpoints of the error bars.
