Hi, I feel like i'm missing something basic here. I'm trying to use set the Name-Value pair in fan plot but I get a "Too many inputs error". Here is the code

historical =  [ 1.0000    2.8046 ;
                2.0000    4.1040 ];
forecast  =   [ 3.0000   28.9874   18.3958   19.6376;
                4.0000    4.8933   27.2659    7.2206];
h = fanplot(historical,forecast)

Which works fine. But when I try to set any Name-value options,

h = fanplot(historical,forecast,'NumQuantiles',14)
h = fanplot(historical,forecast,'FanFaceColor',[0.4 0.4 0.4;1 1 1])

I get the "Too many inputs" error. Am I missing something obvious or am I going crazy?

Jung - do both of the above lines of code generate the same too many inputs error? Also, which version of MATLAB are you using and does it support these name and value pairs. Type

>> ver

to check the version and

>> doc fanplot

to see the documentation.

Hi Geoff, you are right. It was a version problem. I was running into the error on the 2014b version. I was going by the documentation on the website. Gaaaaa....!

The ability to use name value pair arguments with MATLAB "fanplot" was incorporated into MATLAB R2016a and all future releases as mentioned in the link below:

From your description, it sounds like you are using a previous version of MATLAB (R2014b to be exact) which does not have the ability to use name value pairs as arguments to the "fanplot" function.
