Trouble using plots with TabPy #401
Description
I would like to be able to use plots created in Python (i.e. plots generated from matplotlib or seaborn) in my Tableau workbooks. See the below code in my attempt to make a simple sine plot and show it in a Tableau workbook.
`import json
import base64
import numpy as np
import math
import matplotlib.pyplot as plt
from tabpy.tabpy_tools.client import Client
connection = Client('http://localhost:9004/')
def SinePlot(freq, amp):
x = np.array(np.linspace(1,100,100))
y = []
for i in range(len(x)):
y_i = math.sin(x[i])
y.append(y_i)
i += 1
fig = plt.figure()
ax = plt.subplot(111)
ax.plot(x, y)
plt.title('Sine Wave')
plt.legend('sin')
fig.savefig('plot.png')
data = {}
with open('plot.png', mode='rb') as file:
img = file.read()
data['img'] = base64.encodebytes(img).decode("utf-8")
answer = json.dumps(data)
return answer
connection.deploy('SinePlot Func',
SinePlot,
'Plots a sine wave', override = True)
print('done')`
