Plotting with CXBQN

To enable plotting, you must have Python, matplotlib, and numpy installed, and you must enable the CMake option CXBQN_PLOT at configure-time. All plotting utilites live under the namespace •cxbqn.plot. The plotting API is modelled after matplotlib as •cxbqn.plot is simply a wrapper around it. All of the plotting utilities are subject to change. You may view all of the available plotting utilities by printing out the plotting namespace:

$ ./BQN -p •cxbqn.plot
{legend‿title‿show‿save‿namedplot‿plot⇐}

Examples

Simple Line Graphs

plt←•cxbqn.plot
plt.Plot ↕10
plt.Show@

Overlay Multiple Graphs

plt←•cxbqn.plot
x←10-˜↕21
x plt.Plot 2⋆˜x
x plt.Plot 3×2⋆˜x
plt.Show@

Saving Figures

plt←•cxbqn.plot
plt.Plot ↕10
plt.Save "myfig.png"

Titles, Named Plots, and Legends

plt←•cxbqn.plot

x←10-˜↕21
parab←2⋆˜x

"Parabola" plt.NamedPlot x‿parab
"Another Parabola" plt.NamedPlot x‿(2×parab)

plt.Title "Two Parabolas"
plt.Legend@
