Matlab not aligning correct values in excel with the correct x value?

I tried making a boxplot for data that involves different varieties of plants. The x values are the different types of plants used, and the y values is a given number in an excel sheet. I created a boxplot and it appears right, however the x values do not correlate with the correct y values. Is there any way I can fix this? The excel sheet appears to be correct, along with the other sheets (African rice won't merge with the Maize data, however). The code is provided below:

% Plot variability in s* from crop drought experiments.
clear all; close all; clc

% Load data
load FTSW_Thresholds.mat

% merge Millet with Pearl Millet and the four grasses
x=strcmp(Crop,'Pearl Millet');
Crop(x)={'Millet'};
x=strcmp(Crop,'bermudagrass');
Crop(x)={'Grass'};
x=strcmp(Crop,'zoysiagrass');
Crop(x)={'Grass'};
x=strcmp(Crop,'Seashore Paspalum');
Crop(x)={'Grass'};
x=strcmp(Crop,'Turfgrass');
Crop(x)={'Grass'};
x=strcmp(Crop,'Grain');
Crop(x)={'Millet'};
x=strcmp(Crop,'African Rice');
Crop(x)={'Maize'};  

%merge other similar crops
x=strcmp(Crop,'Black Gram');
Crop(x)={'Soybean'};
x=strcmp(Crop,'Black gram');
Crop(x)={'Soybean'};
x=strcmp(Crop,'Groundnut');
Crop(x)={'Peanut'};
x=strcmp(Crop,'Corn');
Crop(x)={'Maize'};
x=strcmp(Crop,'Cowpea');
Crop(x)={'Pigeon Pea'};
x=strcmp(Crop,'A. Rubrum');
Crop(x)={'Red Maple'};
x=strcmp(Crop,'R. Pseudoacacia');
Crop(x)={'Black Locust Tree'};
x=strcmp(Crop,'Ibex Aquifolium');
Crop(x)={'Holly Tree'};
x=strcmp(Crop,'Thuja Plicata');
Crop(x)={'Pacific Red Cedar'};
x=strcmp(Crop,'Hibiscus sp.');
Crop(x)={'Hibiscus'};

crop_name=unique(Crop);

g=zeros(length(crop_name),length(Crop));

for i=1:length(crop_name)      
    g(i,:)=strcmp(Crop,crop_name(i));      
end

boxplot(FTSW_threshold,g','labels',crop_name,'labelorientation','inline')

set(gcf,'Color',[1 1 1])
set(gca,'FontSize',14)
ylabel('Threshold for transpiration decline')
ylim([0 1])

It sure would have made it easier to answer if you had included a screenshot and attached 'FTSW_Thresholds.mat' so we could have run your code ourselves.

Which Excel sheet? The code looks really confusing. Perhaps you want to create a table for the translations e.g. as a cell string matrix instead. Then the replacements can be performed in a loop.

The description of the problem is very vague only: "the x values do not correlate with the correct y values". How could we guess, what is correct and what is not? We cannot even run your code due to the missing inputs.
