Hey guys,
I got a quick question! Consider this image:
http://pl.vc/5upn3
Now I want to represent the thickness of a layer on a flat substrate, which I measured in 121 points before and after a certain step.
The thickness decreases by about 130 nm and I want to represent this decrease in height in one graph.
If I turn the higher bars (orange) transparent enough to see the distribution of the lower bars (green) perfectly, the higher bars are hard to distringuish.
Is there a feature/option where I can give the transparency a gradient, meaning the orange bars are more transparent at a height of 80-120 nm and a lot less transparent at the top?
The caps on top of the orange bars could be normal color (non-transparent) and it wouldn't disturb the rest of the image, then downwards along the height the transparency increases until the green bars are visible.
Is this possible somehow?
Regards,

Hi Hexacyanoferrat,
Your plot is a type of 3D Stacked Bar graph, and I don't know how generally we can approach. But, fortunately in your specific case,
the graph has only two levels, and the height of the bars are constant.
Therefore, you can make similar to your sample by making two complementing 3D bar graphs, and composing with shifting Z
values (tye option of "Shift in Z by percent of scale, 0=bottom, 100=top" in Plot Details dialog) of one chart.
Please see the screenshot below:
Hope this work-around approach works for you.

Hey Hideo,
Thanks for your reply.
Unfortunately your workaround doesnt work for me, I will explain why:
I have 2 sets of Height-measurements, both have a value distribution (i.e. non-constant values):
http://pl.vc/4hak0
http://pl.vc/27luw
I already got the upper half transparent with the normal transparency feature, which is the same result as you got with your workaround.
However, as I have a larger x- and y-space, there are a lot of bars stacked on top of each other, increasing their opacity (try it with 120 bars, you won't see the last one). That means I have to set transparency to at least 85% to be able to see the last green bar in the corner. But then the orange bars are too transparent on top to be able to discern the height profile.
I gather from your reply that a transparency gradient isn't possible, so I will look for other ways to represent my data.
Thank you for your time!
