Hi I'm trying to put a scatterplot on a boxplot. Currently my boxplot plots fine but the scatterplot is giving me issues and I'm not sure why. Both the X and Y variables I input into it are 16x4, the X is a double and the Y is a categorical. This is the code and the error I keep getting.
AHA2 = repmat({'2'}, 4, 1);
AHA3 = repmat({'3'}, 4, 1);
AHA8 = repmat({'8'}, 4, 1);
AHA9 = repmat({'9'}, 4, 1);
AHA14 = repmat({'14'}, 4, 1);
%setup for Wall AHA regions
AHA1 = repmat({'1'}, 4, 1);
AHA4 = repmat({'4'}, 4, 1);
AHA5 = repmat({'5'}, 4, 1);
AHA6 = repmat({'6'}, 4, 1);
AHA7 = repmat({'7'}, 4, 1);
AHA10 = repmat({'10'}, 4, 1);
AHA11 = repmat({'11'}, 4, 1);
AHA12 = repmat({'12'}, 4, 1);
AHA13 = repmat({'13'}, 4, 1);
AHA15 = repmat({'15'}, 4, 1);
AHA16 = repmat({'16'}, 4, 1);
g_test = categorical([AHA2, AHA3, AHA8, AHA9, AHA14, AHA1, AHA4, AHA5, AHA6, AHA7, AHA10, AHA11, AHA12, AHA13, AHA15, AHA16])';
boXP.rr_la.Septum = [WS.S10.rr_la.Septum; WS.S11.rr_la.Septum; WS.S12.rr_la.Septum; WS.S13.rr_la.Septum]';
boXP.rr_la.Wall = [WS.S10.rr_la.Wall; WS.S11.rr_la.Wall; WS.S12.rr_la.Wall; WS.S13.rr_la.Wall]';
boXP.rr_la.WS_ready = [boXP.rr_la.Septum;boXP.rr_la.Wall];
boxplot(boXP.rr_la.WS_ready,g);
hold on;
scatter(g_test,boXP.rr_la.WS_ready);
hold off;
>> Boxplot_Numerical
Error using scatter (line 78)
X and Y must be vectors of the same length.
Error in Boxplot_Numerical (line 165)
scatter(g_test,boXP.rr_la.WS_ready);
I rechecked about 10 times and boXP.rr_la.WS_ready is a 16x4 double. Not sure whats going on, any help is appreciated

Cannot reproduce the error:
Undefined variable "WS" or class "WS.S10.rr_la.Septum".

boXP.rr_la.Septum = [WS.S10.rr_la.Septum; WS.S11.rr_la.Septum; WS.S12.rr_la.Septum; WS.S13.rr_la.Septum]';
boXP.rr_la.Wall = [WS.S10.rr_la.Wall; WS.S11.rr_la.Wall; WS.S12.rr_la.Wall; WS.S13.rr_la.Wall]';
The above two lines create a column vector of1x4(the files inside the bracket are missing so I can only assume) which is then transpossed to 4x1 row vector.
boXP.WS_ready = [boXP.rr_la.Septum;boXP.rr_la.Wall];
This line then takes both Row vectors and converts it to 2x4 array. Again I dont have the files inside the [] so can't comment but most likely it is an issue of how the vectors are appended to each other

" Both the X and Y variables I input into it are 16x4, ..."
As the error message clearly says,
Error using scatter (line 78)
X and Y must be vectors of the same length.
scatter() documentation states for inputs x,y --
x — x values
vector
x values, specified as a vector. x and y must be vectors of equal length.
To use scatter() you must arrange the input data as vectors, not 2D arrays.
