memo

Store a location for later use

Call signature:

memo(id, x, y)

Help text:

memo(id, x, y) stores the location of the data point (x,y) for later use by recall.

x and y may be data coordinates, but more usefully they may be “left”, “center”, “right” for x, or “top”, “middle”, “bottom” for y.

Example:

import qplot as qp

import numpy as np

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

xx = np.arange(0, 2*np.pi, .01)

qp.subplot(1,2,0)

qp.plot(xx, np.cos(xx))

qp.xaxis(' ', [0, np.pi, 2*np.pi], ['0', 'π', '2π'], y=-1, axshift=5)

qp.memo('A', 'center', 'bottom')

qp.subplot(1,2,1)

qp.plot(xx, np.sin(xx))

qp.xaxis(' ', [0, np.pi, 2*np.pi], ['0', 'π', '2π'], y=-1, axshift=5)

qp.memo('B', 'center', 'bottom')

qp.recall(['A', 'B'])

qp.align('center', 'bottom')

qp.text('Phase (radians)')
