    <p>I have this code:</p> <pre><code>from pylab import * from mpl_toolkits.axes_grid.anchored_artists import AnchoredText import numpy as np import matplotlib.pylab as plt fig = plt.figure() ax = fig.add_subplot(111) ann = AnchoredText('If you zoom in or out, i stay here\nbut can you update this text?', prop=dict(size=8), frameon=True, loc=2, ) ann.patch.set_boxstyle("round,pad=0.,rounding_size=0.2") ax.add_artist(ann) delta = 0.025 x = np.arange(-3.0, 3.0, delta) y = np.arange(-2.0, 2.0, delta) X, Y = np.meshgrid(x, y) Z1 = bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0) Z2 = bivariate_normal(X, Y, 1.5, 0.5, 1, 1) Z = (Z1 - Z2) * 10 plt.contourf(X, Y, Z) plt.show() </code></pre> <p>Is there a way to anchor text to be always visible but to also be able to use a <code>set_text</code> method like in text objects to update the containing text? Here i used AnchoredText which is anchored perfectly but i cannot find a method to change the text it contains. In <a href="http://matplotlib.org/users/annotations_guide.html?highlight=anchoredtext#placing-artist-at-the-anchored-location-of-the-axes" rel="nofollow">AnchoredText</a> Matplotlib documentation i cannot find such a method available. If it cannot be done with AnchoredText can it be done with a simple text object?</p> <p><strong>EDIT</strong></p> <p>I accepted the solution from <strong>David Zwicker</strong> and here is a working example for anyone in need of it:</p> <pre><code>from pylab import * from mpl_toolkits.axes_grid.anchored_artists import AnchoredText import numpy as np import matplotlib.pylab as plt import random fig = plt.figure() ax = fig.add_subplot(111) ann = AnchoredText('If you zoom in or out, i stay here\nbut can you update this text?$4.1f$ km s$^{-1}$', prop=dict(size=15), frameon=True, loc=2, ) ann.patch.set_boxstyle("round,pad=0.,rounding_size=0.2") ax.add_artist(ann) delta = 0.025 x = np.arange(-3.0, 3.0, delta) y = np.arange(-2.0, 2.0, delta) X, Y = np.meshgrid(x, y) Z1 = bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0) Z2 = bivariate_normal(X, Y, 1.5, 0.5, 1, 1) Z = (Z1 - Z2) * 10 plt.contourf(X, Y, Z) a = ["hhhhh", "qqqqq", "aaaaaaa","ttttt","yyyyy","oooooooo"] def setanntext(self): ann.txt.set_text(random.choice(a)) plt.draw() buttonax = plt.axes([0.7, 0.05, 0.1, 0.1]) button = Button(buttonax, 'set text',color='0.85', hovercolor='0.95') button.on_clicked(setanntext) plt.show() </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
