A Simple Oriole

A really simple example:

You can write paragraphs like this.

hey = "hello world", 38+4
print(hey hello. This is an executable code block )!

::: #the-id This is a block inside a div with an id the-id. Very cool. Yes. :::

hey = "hello world", 38+4
print(hey hello. This is a non executable block )!

::: #another-id

More complicated example

:::

x = [1,1]
for i in range(12):
    x.append(x[-1] + x[-2]) 
print(', '.join(str(y) for y in x))

A Chart

::: #this-example :::

%matplotlib inline
import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 3*np.pi, 500)
plt.plot(x, np.sin(x**2))
plt.title('A simple chirp');

Seaborn Example

from __future__ import print_function, division

%matplotlib inline
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd

x = np.linspace(0, 10, 1000)
plt.plot(x, np.sin(x), x, np.cos(x));

import seaborn as sns
sns.set()
plt.plot(x, np.sin(x), x, np.cos(x));

Interactive widgets

%matplotlib inline
from IPython.display import Image
from IPython.html.widgets import interact
from numpy import pi, cos, sin
import numpy as np
import pylab as plt
import seaborn as sns
sns.set()

def plot_fringe(bl_length, wavelength):
    """ Plot the fringe function for a baseline (see Fig 1)

    bl_length:      distance between antennas, in m
    wavelength:     wavelength, in m
    """
    theta = np.linspace(-np.pi, np.pi, 401)
    l = sin(theta)
    F = cos(2 * pi * bl_length * l / wavelength)
    F2 = cos(2 * pi * 2 * bl_length * l / wavelength)

    plt.plot(l, F, c='#cc0000', label="Baseline 1-2")
    plt.plot(l, F2, c='#0000cc', label="Baseline 1-3")
    plt.xlabel("$sin(\\theta)$")
    plt.ylabel("Fringe amplitude")
    plt.ylim(-2, 2)
    plt.legend()

f = interact(plot_fringe, bl_length=(1, 100), wavelength=(1, 100))
