Tutorial notebook: minimal working example

Here we use some minimal example data.

[1]:

import numpy as np

[2]:

# Load your data. Here we're creating random data.
coords = np.random.randn( 20000, 3 )
fields = np.random.random(size=coords[:,0].size)

Format Data for Firefly

[3]:

from firefly.data_reader import ArrayReader

[4]:

my_arrayReader = ArrayReader(
    coords,
    fields=fields,
    write_to_disk=False)

datadir is None, defaulting to /Users/agurvich/research/repos/Firefly/src/firefly/static/data/Data
Make sure each field_array (1) has a field_filter_flag (0), assuming True.
Make sure each field_array (1) has a field_colormap_flag (0), assuming True.
Make sure each field_array (1) has a field_radius_flag (0), assuming False.
PGroup_0 - 20000/20000 particles - 1 tracked fields

Display Inline

[5]:

from firefly.server import spawnFireflyServer,quitAllFireflyServers

[6]:

process = spawnFireflyServer()

Waiting up to 10 seconds for background Firefly server to start....done! Your server is available at - http://localhost:5500

[7]:

from IPython.display import IFrame
url = "http://localhost:5500/combined"
IFrame(url, width=1000, height=500)

[8]:

# Send data to the server.
# Wait until it loads to run this command
my_arrayReader.sendDataViaFlask()

Posting data on port 5500...data posted!
