Shade area between two curves

Function shades the area between two vectors.

Description

This routine will shade the area of a 2-D plot between two user defined vectors. Simply pass the two vectors, and their corresponding horizontal coordinates, select your fill color and transparency level and viola! You have a figure that is colored in between the two input vectors.

Great! Solves a common problem.

[Chris Klink]

Works great, but apparently only when datapoint are horizontally organized (one row). If it's a column it doesn't work. You could mention this in the file.

[Matthias Brunner]

Very nice. Thanks!

[Marc Ferrer]

Wonderful function.

[H W]

Exactly what I needed. Thanks for posting!

[Luke Taylor]

Just what I needed. Thanks!

[Housam binous]

Great job. Thanks for all.

[M H]

lovely function but it is removing box around figure as consequence of transparency.

[W. H. Brave]

Very good file, thank you.

if you make I run the following example, matlab logs me off my user account on SuSe 10.2

for i=1:25
  figure
  % copy the jbfill.m example from the comments here.
  close
end

Thanks, exactly what I needed!
Also thanks to Chris: put data in row vectors!

[W. Johns]

Good file, but the colour disappears when I switch to a vertical log scale. How can I fix this?

[Yasser Soliman]

Great. This was very helpful and saved me lots of time to figure out the exact work that you've done. Thanks!
On another note, I need a few vector-couples the area between which need to be shadded, on the same plot. How can I incorporate that?

[Luis Concha]

Very, very helpful and extremely easy to use. Great for confidence intervals!

[ursula larke]

thank you!!!! this came in REALLY handy! easy to use, well documented! :)

works great,thanks!
the "transparancy" option comes with a caveat: it will switch the renderer to opengl. After that, a vector export is not possible anymore (matlab limitation). set to 1.0 to avoid this problem.

[Andranik Valedi]

Beautiful.

[Matlaboscope]

good but row vectors VS column vectors as input does matter.

[Robert Cumming]

very good, and commented well (does what it says on the tin)

[Redmond]

This function is great, thanks very much. I was hoping to use it to highlight the time-periods for which there was a statistical difference between the two lines. After creating the basic plot, I created a new matrix which specifies the time-points of interest (statistcially significant) in the first column, and the relevant data points for the two lines in the 2nd and 3rd column. I then ran jbfill on this. Unfortunately because the periods of interest are non-contiguous the function fills in the area in between. Is there a way to make it so that it wil only shade in areas at the specific time-points I have specified?

[Grzegorz Knor]

Very smart solution.

[Ulrich Sachs]

Very nice. But because of the transparancy, Matlab switches to OpenGL, which leads to vanishing axis. To avoid that I just make the axis lines thicker set(gca,'LineWidth',1.0).
Because logarithmic plots do not support OpenGL, you can not draw transparant areas in logarithmic plots.

[Jakob]

Simple and straight forward! Just what I needed.

[Juan]

great

[Brais]

nice function, nice help, straightforward use

[Clara]

Easy to use, and very useful... at least for those of us working in geophysics. Thanks

[Javad]

TERRIFIC! Thanks.

[Timothy Kinyanjui]

Great function

[Vincent]

Works great, thanks!
