Simple Slider Control¶

Sliders can now be used in Plotly to change the data displayed or style of a plot!

In [2]:
import plotly.plotly as py
import numpy as np

data = [dict(
        visible = False,
        line=dict(color='#00CED1', width=6),
        name = '𝜈 = '+str(step),
        x = np.arange(0,10,0.01),
        y = np.sin(step*np.arange(0,10,0.01))) for step in np.arange(0,5,0.1)]
data[10]['visible'] = True

py.iplot(data, filename='Single Sine Wave')
In [3]:
steps = []
for i in range(len(data)):
    step = dict(
        method = 'restyle',
        args = ['visible', [False] * len(data)],
    step['args'][1][i] = True # Toggle i'th trace to "visible"

sliders = [dict(
    active = 10,
    currentvalue = {"prefix": "Frequency: "},
    pad = {"t": 50},
    steps = steps

layout = dict(sliders=sliders)

fig = dict(data=data, layout=layout)

py.iplot(fig, filename='Sine Wave Slider')
