Hello,
I'm trying to create a box plot from an array in a text file. However I'm having an issue with my x tick labels. They're only being shown for the third set of data. Any ideas?
(P.s. I'm fairly new to Matlab so sorry if my code is long winded, I know it could have been written in a much nicer way!!)
Thanks in advance
Tab = readtable("Validation.txt");
TABLE=table2array(Tab);
Data=TABLE(:,:);
X1= [1 2 3];
X2=[4 5 6];
X3=[7 8 9];
hold all
boxplot(Data(:,1:3),'notch', 'on','Colors',"r","Positions",X1,'Labels',{'1mm A','1mm B','1mm C'})
boxplot(Data(:,4:6),'notch','on','Colors',"b",'Positions',X2,'Labels',{'1.5mm A','1.5mm B','1.5mm C'})
boxplot(Data(:,7:9),'notch','on','Colors',"g",'Positions',X3,'Labels',{'3mm A','3mm B','3mm C'})
xlim([0 10]);
set(gca,'FontSize',10,'XTickLabelRotation',90)

Managed to fix this (for anyone that stumbles across a similar issue in the future!). The issue was that the figure was only displaying three ticks (the final 3) and so when it went to assign tick labels, it only assigned them to the final three. I inserted the final line:
boxplot(Data(:,1:3),'notch', 'on','Colors',"r","Positions",X1)
boxplot(Data(:,4:6),'notch','on','Colors',"b",'Positions',X2)
boxplot(Data(:,7:9),'notch','on','Colors',"g",'Positions',X3)
xticklabels({'1mm A','1mm B','1mm C','1.5mm A','1.5mm B','1.5mm C','3mm A','3mm B','3mm C'})
set(gca,'xtick',1:9); %inserted this line!!
Which gave the plot 9 ticks, allowing all 9 tick labels to be displayed.

That's just added the first 3 labels to the final 3 boxes... :(
