# Chart for wall hygrometric physic (or how to create a chart with custom x axis intervals?)

Posted on April 18th, 2013 in Charts and Graphs - 6 comments

Livio, one of our readers from Italy sent me this interesting problem in email.

I would like to prepare an xy linear graphic as representation of the variation of temperature trough a wall between two different bulk temperature i.e. outside and inside a house. This graphic should show the temperature gradient trough the wall thickness. The wall is normally made by different construction materials (different layers, as bricks, insulation, …..) and so the temperature change but not as a straight line with only one slope, instead as few lines with different slopes (see below figure) Calculations are not difficult, and also prepare the graphic also not difficult.

But, I am looking a beautiful solution for x-axis. X-axis should be divided not with constant interval, instead with different length between each sub-division exactly as the different thickness of the wall. This is a correct graphic, because you can show the correct slope of each straight line though each layer of the wall.

Well, I know as much about wall hygrometric physics as cavemen knew about pivot tables.

But I know Excel well enough to know that we can easily create such a chart.

Although you can create this chart easily, explaining how to do it can be lengthy. So I made a short video. Watch it below.

(Cant see the video, watch it on our Youtube channel)

## Do you use fake axis labels?

The basic idea in this chart is to fake x axis labels thru dummy series. I use this technique often, especially when making charts like milestone chart, waterfall chart etc.

PS: Thanks to Livio for asking this question 🙂

XY chart labeler has been of phenomenal use for me in the last 3 years. Very handy and trusted tool for me.

2. Great trick!

Nice tip

The coolest trick in this video was to copy data and paste it into the chart as additional series!!! 🙂
