Introduce plots in tweets

[fuglede]

It's relatively straightforward to include images in Twitter updates. In our case, it would make sense to include a small image showing the current forecast.

When you say small image are you referring to the green and black icons that are being returned in the json from the api? Or will it be from another known source?

I was actually thinking something more like the plot of the forecast that's currently on the web page:

The plot is currently rendered client-side, but it should be possible to render it when generating the tweets as well.

[Alig1493]

I saw that the plot of the referred forecast above is rendered by the front end using the plot-data. I am not being able to use that plot-data in the response to render a graph using altair as you had previously mentioned. My initial efforts were as follows:

import altair
import json
import requests

url = "https://xn--grnstrm-r1ae.nu/api/v1/current-emission-intensity"
response = requests.get(url)
jd = json.dumps(response.json().get("plot-data"))
altair.Chart.from_json(jd)

Shortened Traceback:
AttributeError: 'list' object has no attribute 'get'

I may have made mistakes in my approach and I'd appreciate if you'd help me navigate them. Thanks for your comments thus far.

In your traceback, which of the two get is it complaining about? Your snippet doesn't define requests; perhaps you accidentally replaced the imported module with a list, or response has somehow become a list? For what it's worth, if I import requests before calling your snippet, it does work as expected.

[Alig1493]

I forgot to paste the requests in the snippet. Did it really work because I tried it again after your comment and I'm still getting the same error for the plot-data in the response_data for the url given.

[fuglede]

Yep, here's with I get:

$ cat test.py
import altair
import json
import requests

print(altair.__version__)
print(requests.__version__)
url = "https://xn--grnstrm-r1ae.nu/api/v1/current-emission-intensity"
response = requests.get(url)
jd = json.dumps(response.json().get("plot-data"))
print(altair.Chart.from_json(jd))


$ python test.py
4.1.0
2.26.0
alt.VConcatChart(...)

[Alig1493]

4.1.0
2.26.0
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

This is my output unfortunately for the same snippet above. What version for python are you using?

[fuglede]

What is the value of response.json() in your case?

[Alig1493]

plot_data_response.txt

[fuglede]

That looks about right as well; as in,

altair.Chart.from_json(json.dumps(requests.get("https://github.com/groenstroem/twitter/files/7273244/plot_data_response.txt").json().get('plot-data')))

does what it should. You'll have to either get the full traceback, or debug each step.
