Plotly layout with background image from local file
I have the same problem as stated in this question: I want my plot to have a background from a local png file.
Using plotly's example, which uses an image from the web, works.
Using a path to my local image, with or without absolute path, does not work.
Encoding as per the answer to this other question does not help.
import base64
import os
import plotly.plotly as py
import plotly.graph_objs as go
from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
import numpy as np
trace1= go.Scatter(x=[0,0.5,1,2,2.2],y=[1.23,2.5,0.42,3,1])
with open(os.getcwd() + "/resources/office_map.png", "rb") as image_file:
encoded_string = base64.b64encode(image_file.read()).decode()
# Add the prefix that plotly will want when using the string as source
encoded_image = "data:image/png;base64," + encoded_string
layout= go.Layout(
title='My title',
images= [dict(
source= encoded_image,
xref= "x",
yref= "y",
x= 0,
y= 10,
sizex= 744,
sizey= 1052,
sizing= "stretch",
opacity= 0.5,
layer= "below")])
fig=go.Figure(data=[trace1],layout=layout)
plot(fig)
How hard can it be to get a local image as background? How do you do it?

I needed to read about the x and y parameters of the images dictionary. I had changed the y before testing the encoding solution, and the image appeared way outside the plot. How silly. Setting y to 3 instead fixes it.
