Error normalising multiple data sets with the same parameters
显示 更早的评论
I've compiled 5 different datasets into a 3D plot by loading the relevant plots using the method below:
openfig('3DPlot1.fig');
Plot1 = get(gca,'Children');
Plot1_X = get(Plot1, 'ZData');
Plot1_Y = get(Plot1, 'ZData');
Plot1_Z = get(Plot1, 'ZData');
but now need to normalise the temperature (Z axes) axes for all datasets obtained this way.
I've tried using the following method from the normalize() page:
[N,C,S] = normalize(___) additionally returns the centering and scaling values C and S used to perform the normalization. Then, you can normalize different input data using the values in C and S with N = normalize(A2,'center',C,'scale',S).
So it looks like this in my code:
[Plot1_T, C, S] = normalize(Plot1_Z);
Plot2_T = normalize(Plot2_Z, 'center', C, 'scale', S);
But I'm getting the error "Error using normalize. Too many output arguments.". Could this be something to do with the way I'm loading the data as I don't see any error with typing in the code? If so, how else could I normalise all the data? I can't normalise them separately as it will affect the 3D plot shapes once all datasets are shown.
Thank you!

Assuming you already have gotten the ZData of each object whose ZData you want to normalize "globally", you can do this to normalize them all on a common basis (based on the min and max over all ZData):
% you have done this already:
Plot1_Z = get(Plot1, 'ZData');
Plot2_Z = get(Plot2, 'ZData');
Plot3_Z = get(Plot3, 'ZData');
Plot4_Z = get(Plot4, 'ZData');
Plot5_Z = get(Plot5, 'ZData');
% put the ZData all together in a column vector:
all_Z = [Plot1_Z(:); Plot2_Z(:); Plot3_Z(:); Plot4_Z(:); Plot5_Z(:)];
% get the min and max values:
min_Z = min(all_Z);
max_Z = max(all_Z);
% normalize each to [0,1] using min_Z and max_Z:
Plot1_Z = (Plot1_Z-min_Z)/(max_Z-min_Z);
Plot2_Z = (Plot2_Z-min_Z)/(max_Z-min_Z);
Plot3_Z = (Plot3_Z-min_Z)/(max_Z-min_Z);
Plot4_Z = (Plot4_Z-min_Z)/(max_Z-min_Z);
Plot5_Z = (Plot5_Z-min_Z)/(max_Z-min_Z);
% update the plots with the normalized ZData:
set(Plot1, 'ZData', Plot1_Z);
set(Plot2, 'ZData', Plot2_Z);
set(Plot3, 'ZData', Plot3_Z);
set(Plot4, 'ZData', Plot4_Z);
set(Plot5, 'ZData', Plot5_Z);
