Area Chart: How to Specify a "Base" for a Semilog Plot?
I have copied below the code for a semi log plot. (This has been adapted from one of the examples in the Adobe Flex documentation.) The y-axis is the log axis.
The fills are done with respect to y = 1. Is there a way to get the fills done with respect to y = 0.1?

Any chance you could draw a diagram showing how you want the chart to look
like? I am having a hard time understanding. If someone else gets it,
perhaps they can respond?
P.S. You can use an online image editing tool like: https://onpaste.com/ to
draw your requirements.
Thanks,
Om

Thanks for the reply.
I got the same graph as you did. This is NOT what I want. It uses y=1 as the "base". I want y = 0.1 as the base. In other words, areas above 0.1 must be filled. In the picture you sent,
. the area to the left of the rising line should NOT be filled.
. the area to the right of that line must be filled from y=0.1. Right now, only the part above y=1 is filled.
. The next area should not be filled.
. The rightmost area should be filled all the way to y=0.1 if possible.
It may be easier to see things with form="step".
y = 1 is not a special line. y = 0.1 (which is practically the x axis) is. All areas above it must be shaded. [y=1 is a special line for the log plot since log 1 = 0. However, I want areas above the real 0 to be shaded.]
Thanks again.
Your reply went to my Spam folder. I seldom check here for good messages.

In the attached image, I have areas the parts that should not be there and added the areas that should be there. [Sorry it looks like something a child draws :-)]

Ah, I get it now. Sorry for being dense :-) I will try a couple of things
to see if that is possible, when I get a chance.

In simple terms, areas between the function being drawn (i.e., the thick green curved line) and y = 0.1 should be shaded.
What it currently does is to shade areas between the function being drawn and y = 1.

In case the above is not clear, if you copy the code and run, what I am
asking will be clear -- I want the areas above the y = 0.1 horizontal line
to be shaded. Currently, by default y = 1 is taken as the "base" and areas
above and below are filled. I want y = 0.1 to be the base.
