LineGlyph¶

LineGlyph wraps Axes.plot, Axes.bar, and Axes.fill_between for line, bar, and band plots. y may be 1-D (one series) or 2-D (one series per column).

1. Line plot (multiple series)¶

In [2]:

y = np.column_stack([np.sin(x), np.cos(x)])
glyph = LineGlyph(x, y)
fig, ax, lines = glyph.line(label=['sin', 'cos'], title='Lines')
ax.legend()

y = np.column_stack([np.sin(x), np.cos(x)]) glyph = LineGlyph(x, y) fig, ax, lines = glyph.line(label=['sin', 'cos'], title='Lines') ax.legend()

2. Bar chart¶

In [3]:

xb = np.arange(6)
glyph = LineGlyph(xb, np.array([3.0, 5.0, 2.0, 8.0, 4.0, 6.0]))
fig, ax, bars = glyph.bar(title='Bars')

xb = np.arange(6) glyph = LineGlyph(xb, np.array([3.0, 5.0, 2.0, 8.0, 4.0, 6.0])) fig, ax, bars = glyph.bar(title='Bars')

3. Band / envelope (fill_between)¶

In [4]:

upper = np.sin(x) + 0.3
lower = np.sin(x) - 0.3
glyph = LineGlyph(x, upper)
fig, ax, band = glyph.fill_between(y2=lower, alpha=0.3, title='Band')

upper = np.sin(x) + 0.3 lower = np.sin(x) - 0.3 glyph = LineGlyph(x, upper) fig, ax, band = glyph.fill_between(y2=lower, alpha=0.3, title='Band')
