During the Reddit Blackout i made a graph showing the posts and comments/day (Link).
Some days ago i was asked to make an Update so here it is.
Source Data is from here and contains the same Data as some may know from here. Only difference is that the post and comment count is summed over the day.
EDIT:
The Original Post Data contained inconsistent Data points on each day (see here).
This is the corrected Chart, which uses the difference in Post IDs between the days to calculate the daily number (adjusted to s between the api calls):
I also adjusted the values to 10^6 and adjusted the y-axis ranges, I hope this makes it easier on the eyes.
For people complaining on the mixed chart: Double column looks bad with 2Y-Axis, and double lines looks too empty. 2Y-Axis are necessary cause of the difference in scaling of the posts and comments data, only other option would be an axis break.
I just populated the new data into the sheet that I used for my previous sheet, on a request for an update on the data.
I would have used a double column chart back than but it looked bad with double y-axis. Double lines is also less visually pleasing here in my opinion (too much empty space). I also depicted the data values in the columns in the old chart since it had less day points so the columns were wider and the values still readable.
Thats why I mixed both chart types.
I agree that bar chart with double y axis looks bad, ive always been confused whether the bars are in addition or separate, e.g. blue ontop of orange, blue = orange + blue, or blue just = blue, i only recently realised it was the latter, it can be harder to read aswell since it doesnt start from the bottom. Also i get what you mean about the double lines with empty space, tho personally it doesnt bother me in the slightest
