#### `plerry`: Draw y error bar

`plerry (` | n,
| x,
| ymin,
| ymax`)`;

Draws a set of ``n`` vertical error bars, the `i`'th error bar extending from ``ymin`[i]` to ``ymax`[i]` at x coordinate ``x`[i]`. The terminals of the error bar are of length equal to the minor tick length (settable using `plsmin`).

`n` (`PLINT`, input)

  Number of error bars to draw.

`x` (`const PLFLT *`, input)

  Pointer to array with x coordinates of error bars.

`ymin` (`const PLFLT *`, input)

  Pointer to array with y coordinates of lower endpoint of error bars.

`ymax` (`const PLFLT *`, input)

  Pointer to array with y coordinate of upper endpoint of error bar.

Redacted form:

- General: `plerry(x, ymin, ymax)`

- Perl/PDL: `plerry(n, x, ymin, ymax)`

This function is used in example 29.
