Every Inchie Monday: x-axis

This week's word at Every Inchie Monday is x-axis.  Wow.  I love to work outside the box, but this one is the box.  I came up with very little except a chart.  I have a friend who said I should just draw a line and call it the x-axis, without adding the y-axis, but I thought that would be as confusing as trying to explain the idea is.

So here is my very boring, not even pretty, chart.  I couldn't even think of anything interesting to graph.  And I didn't  include the sometimes used z axis because I don't know what it is for.  I liked math in school, but would never survive a job in today's world that required the use of graphs.

One slightly more interesting thing I found while researching the topic is that there is a company called X-axis that manufactures tires for racing bikes, so here is a second inchie:

I guess some week's the brain simply won't function creatively.  I'm looking forward to inspiration from other people's inchies.

Hope your week is in the black.
