This graph gives the impression that the total installation number has been multipliés x4 or X5 while it is not the case when looking at the raw numbers.
Any variation can look impressive if you zoom enough, that’s why you need a baseline at 0. This way you see thé entire scale of the phenomenon
Yes but the graph goes from 2 rectangles above the bottom line to 8 rectangles above the bottom line in that final surge.
So visually, it looks like it has quadrupled.
While I agree for the sake of clarity, a bigger problem is that it only goes back less than 2 months. Has the number of installs been steady at 7k for a long time? Or does it fluctuate wildly like this occasionally for reasons totally unrelated to laws?
I was just clarifying the original comment about the baseline not being 0.
Tbh, I hadn’t even looked at it properly and only noticed now that the timeline isn’t one month per box.
But you don’t get that percentage from looking at the graph. You get that from looking at the numbers.
The graph height increases by 300% in the last 3 months.
That graph is trash. The baseline needs to be at zero.
Could you please clarify why the baseline needs to be at 0? I’m genuinely curious.

How so? It goes from ~7 to ~11. That’s not even x2.

That graph hurts my data scientist heart
It’s common practice to cut the y axis, did you guys not cover that in visualisation?
No it doesn’t.
It’s meant to illustrate a change and it does so perfectly fine. It’s not a scientific paper.
It’s a 32-34% increase looking at the graph. That’s significant enough to shout about.
Imagine any change you could make surprising competition by 25% in any market. That’s huge.
Did you know that disco record sales were up 400% for the year ending 1976, if these trends continue…AY!
Define “perfectly fine”. It is clearly exaggerating the change. At a glance it looks more like a 5 times increase, not a 30% increase.
Of lies, damned lies, and statistics this graph is certainly one of them.
True.
But you don’t get that percentage from looking at the graph. You get that from looking at the numbers.
The graph height increases by 300% in the last 3 months.
You could say the same about a 0.001 difference if you zoom in on the y-axis. You don’t know what you’re talking about.
A 0.001 difference on a 0.004 total would be worth showing.
That was a bad example. Try 1,000,000 moving up to 1,000,069.
I’m sticking with relevance. A >25% rise is what we’re talking about.
A 25% raise would show up with the y shits at zero. As would any significant increase.
