QPlot: overline

≡

overline

Draw a line above data with a text above it

Call signature:

overline(xx, yy, text=None, datadist=None, textdist=None, minlen=None)

Help text:

overline([x1, x2], y, text), draws a horizontal line just above (x1, y) to (x2, y) and places the given text over it.

overline([x1, x2], [y1, y2], text), draws the line just above the larger y-value and extends a vertical line down to the smaller y-value.

The whole thing is displaced by a distance overlinedist from the data, and the text placement uses the absolute value of textdist.

If overlinemin is non-zero, a vertical line is drawn on both ends.

The text argument may be omitted.

Optional arguments datadist, textdist, and minlen override global settings.

Example:

import qplot as qp

import numpy as np

qp.figure('overline', 3, 3)

xx = [1, 2]

yy = np.array([3, 4])

dy = np.array([.5, .75])

qp.bars(xx, yy, .5)

qp.errorbars(xx, yy, dy)

qp.overline(xx, np.max(yy+dy), '*')

xx = [3.5, 4.5]

qp.bars(xx, yy, .5)

qp.errorbars(xx, yy, dy)

qp.overline(xx, yy+dy, '+')
