# ## <hr> Setup

# In[1]:


import os
from lightning import Lightning

from numpy import random


# ## Connect to server

# In[2]:


lgn = Lightning(ipython=True, host='http://public.lightning-viz.org')


# ## <hr> Make a histogram

# We'll generate some normally distributed values and make a histogram

# In[3]:


values = random.randn(100)
lgn.histogram(values, 10, zoom=False)


# Change the number of bins

# In[4]:


lgn.histogram(values, 50, zoom=False)


# ## <hr> Zooming for dynamic bins

# If we turn on zooming, we can change the number of bins dynamically by zooming in and out -- try it!

# In[5]:


lgn.histogram(values, 25, zoom=True)
