Add support for shading area between two lines

[andermoran]

Can we get support to shade above one line until another? This is helpful if we have to lines (lower range & upper range) and we went to shade the possible values between these two lines. So far, I can see we can only cutoff to a constant value.

Interesting,
We will consider it.

Also if it is possible, provide an image and demonstrate your idea.
It helps me and other people.

This is a graph with 80% and 90% confidence intervals. See how the range of values between the confidence intervals is shaded? I'd like to be able to plot the line, a line above it, and a line below it (I can do this all right now) but I'd like to shade between the line above and the line below (I can't do this).

Thank you for the details.

Hi, has anyone suggestions about how we should configure this? I just got it working, but i added a bool property "cutOffPreviousLine" on BarAreaData, so it's like the cutOffY property but then a cutOff by the previous line. Suggestions for a better naming is welcome :-)

[imaNNeo]

I think we can have a property outside of the BarAreaData.
I suggest to have it in the LineChartData directly, and have a new member called BetweenBarsData.
Then we can specify fromLine (index of line) , toLine (index of line), color, gradient,...
What do you think?

Resolved and added betweenBarsData field in 0.6.1,
check this sample:

It will be great if you implement your sample and submit a PR to add it to our samples.
Thanks!
