These are two different questions.
Let's separate the discussion.
1. Can line chart support a value based X axis?
The answer is no, because this is the common use of a line chart. A scatter
chart can have a line, and that it on our feature request list, but a line
chart is almost always category based. Look in Microsoft Excel for instance,
and you'll see a similar behavior.
2. Can line chart support a number datatype even though it treats it as
category/label based?
In this case, it's a more delicate question.
Usually you can circumvent this problem by casting to String in the
javascript.
It is also in our roadmap to add a means in the query langauge to do type
casting.
Do you still see this as a needed feature to support numbers?
