QUESTION
I'm running a Scrapy spider inside a script and I want to assign the scraped data to a variable, rather than output to a file, and read that file to get the data.
Right now the spider is outputting the data to a json file, I then read this data, arrange the data to my needs, and then delete the json file from the spider deleted (mostly because I couldn't figure out how to overwrite the spider output). This works and does what I want but definitely seems pretty brute force, is there a more efficient way that I can access the spider data without having to first output it to a json?
This is my code

I have taken a look at other related questions but unable to understand or change this to get it working. Basically i am trying to save a pdf of presented flot data contained in tab0 . for some reason the pdf output cuts half the page off, even though I am using the largest size a0 and it is also missing the legend of charts, here is the code.

Answered 2017-Jun-25 at 02:53I'm facing the same issue, I found that it's not the problem of jsPDF page size, but the html2canvas.
If you indicate canvas option to html2canvas, then html2canvas won't probably capture the element $('#content').get(0)
by its width, it will capture this element by the width of whole window, if the width of the canvas is less than the window's, the captured picture cutting off.
have a try :
canvas.width = document.body.clientWidth
It's not a final solution, but works for me.
