Histc function, bin edges error

Hi,

I am using the code below to overlay a cdf plot on a histogram (top code). I want to specify the bin edges using the histc function (below code). But, I'm getting an error using the histc function below. Would anybody know what I'm doing wrong?

Thanks

[y2,x2] = ecdf(y);
[y1,x1] = hist(y);
plotyy(x1,y1,x2,y2,@(x,y)bar(x,y,1,'c'),'stairs')

x = 110:10:220;
  [y2,x2] = ecdf(y);
  [y1,x1] = histc(y,x);
  plotyy(x1,y1,x2,y2,@(x,y)bar(x,y,1,'c'),'stairs')

X must be same length as Y.

Error in @(x,y)bar(x,y,1,'c')

I think you want to make sure that everything is a row vector or every thing is a column vector.

x = 110:10:220;
  [y2,x2] = ecdf(y);
  [y1,x1] = histc(y,x);
   y1 = y1';
   x1 = x1';
  plotyy(x1,y1,x2,y2,@(x,y)bar(x,y,1,'c'),'stairs')

% Make sure that x1 x2 y1 y2 all are either columns or rows.

Hi,

It is still giving an error, "X must be same length as Y".

But x are the bin edges? and y is the data, why would they be the same length?
