I am writing an essay in which I am reporting the data provided on this line graphenter image description here And I came to the point where I need to describe the changes in the industrial use.

So I wrote:

In 1900, the domestic use stood at 100 km3 and this value was steady over the next 40 years until 1940 where the industrial use showed a significant rise to hit the 1,000 km3 point in 2000.

Is the usage of the conductive pronoun where correct in the context?

  • A Google search returns just 3 instances of the collocation "conductive pronoun". Luckily, one of them is some blogger claiming it's an alternative name for a relative pronoun (for him, perhaps, but obviously not for many others! :) Aug 28, 2018 at 13:02

    Because the cited text is in the context of a graph (which represents "time" on a spatial axis), it's quite natural to use "locational" where rather than "chronological" when. But this apparent "looseness" sometimes occurs in other contexts where / when there's no obvious reason to justify the choice. Aug 28, 2018 at 13:08

I think the contradiction here is between referring to both real time and its graphical interpretation (time vs space): year numbers are not defined as graph points, and the verbs are in past tense (like in a usual event description). If you use terms like '1940 point' and '1,000 km3 value' plus change verbs' tense to Present, then 'where' (1940 point, where the value starts to rise, etc.) and the rest things will be OK to describe the graph.
