Problem plotting csv data: Attempt leads to 'TypeError: dict expected at most 1 arguments, got 2'

📊 Plotly Python

Hi,

I would like to plot csv data (where one column such as ‘X’ has shape (102791,)), leaning on https://plot.ly/python/user-guide/,

df = pd.read_csv(‘file.csv’)
x=df[‘X’]
y=df[‘Y’]

I guess that the length of X is too large so I’d like to plot only, say the 10 first elements.

In order to do this and to avoid problems with ‘dictionary format’ I create arrays
a = np.array([ i for i in range(10)]) instead of x (since the latter has a wronh format (time)), and
A = np.array([ y[i] for i in range(10)])

The printed values of these arrays are:

a = [0 1 2 3 4 5 6 7 8 9]
A = [ 252.62563 252.112328 252.966952 252.283861 252.865349 252.182848
251.283296 250.153394 252.018362 251.242277]

Then I try to plot these values using
import numpy as np
import pandas as pd
import csv
import plotly.plotly as py
import plotly.graph_objs as go

trace1 = go.Scatter(a[:],A[:], marker={‘color’: ‘red’, ‘symbol’: 104, ‘size’: “10”},
mode=“markers+lines”, text=[“one”], name=‘1st Trace’)
data=go.Data([trace1])
py.iplot(data, filename=‘simple-plot-from-csv’)

And no matter what I try get constantly the following error:

Traceback (most recent call last):
File “first.py”, line 119, in
mode=“markers+lines”, text=[“one”], name=‘1st Trace’)
File “/home/opt-user/Enthought/Canopy_64bit/User/lib/python2.7/site-packages/plotly/graph_objs/graph_objs.py”, line 373, in init
d = {key: val for key, val in dict(*args, **kwargs).items()}
TypeError: dict expected at most 1 arguments, got 2

I would be most grateful for help.
Thank you!

Hi there,
It looks like you have not set x and y in your Scatter object. The following should work for you:

a = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
A = [ 252.62563, 252.112328, 252.966952, 252.283861, 252.865349, 252.182848,
251.283296, 250.153394, 252.018362, 251.242277]

import numpy as np
import pandas as pd
import csv
import plotly.plotly as py
import plotly.graph_objs as go

trace1 = go.Scatter(x=a, y=A, marker={'color': 'red', 'symbol': 104, 'size': "10"},
mode="markers+lines", text=["one"], name='1st Trace')
data=go.Data([trace1])
py.iplot(data, filename='simple-plot-from-csv')

Hi Chelsea,
Thank you for your reply.
I tried your suggestion but unfortunately I get another error message. I wonder if I did something wrong…

plot

plotly.exceptions.PlotlyLocalCredentialsError:
Couldn’t find a ‘username’, ‘api-key’ pair for you on your local machine. To sign in temporarily (until you stop running Python), run:

import plotly.plotly as py
py.sign_in(‘username’, ‘api_key’)

Even better, save your credentials permanently using the ‘tools’ module:

import plotly.tools as tls
tls.set_credentials_file(username=‘username’, api_key=‘api-key’)

For more help, see Plotly Python Graphing Library.

Did I understand something wrong? Is this package not free?
Many thanks
