I have seen how to do it on the 2017 release, but wondered if there was a way to get categories on the x-axis of a bar chart as opposed to just numbers on the 2016b release?
MATLAB: In 2016b is there a way to get categories on the x-axis of a bar chart

" I have been trying to plot bar with different colors"
For newer releases, this is fairly straightforward (demo) but for r2016a you can make a diagonal matrix with a stacked bar chart so that every bar is editable.
figure(); y2 = [64.5, 54.6, 44.7, 24.8, 52.2, 6.6, 3.2, 5.2, 52.4, 5.1];bh = bar(1:numel(y2),diag(y2),'stacked','FaceColor', 'c'); %specify default color
% Set specific colors
bh(1).FaceColor = 'r'; %bar 1
bh(2).FaceColor = 'b'; %bar 2....
"I'd also like to plot yaxis with numbers and add names in the x-axis"
Not sure what you mean here. Numbers are already present on the y axis by default. To add names in the x axis,
set(gca,'XTick', 1:numel(y2),'XTickLabel',{'one','two','three','pi','four','five','foo','bar','ali','done'})
From MATLAB R2019b this workflow have been implemented with the use of XEndPoint and YEndPoint : https://www.mathworks.com/help/releases/R2020b/matlab/ref/bar.html?#mw_735ee38d-9d9f-40cd-b02a-8266af7184d9
Before MATLAB R2019b, it is possible to programmatically add text labels above the bars on a plot. These labels can be used to indicate any interesting features of the data set, such as statistical significance or the associated p-values of each bar.This can be done using a "for" loop that loops over each bar in the plot and adds an appropriate label using the "text" function. Refer to the following example code for a simple demonstration on how to do this:
% Generate random data
data = 10*rand(5,1); figure; % Create new figure
hbar = bar(data); % Create bar plot
% Get the data for all the bars that were plotted
x = get(hbar,'XData'); y = get(hbar,'YData'); ygap = 0.1; % Specify vertical gap between the bar and label
ylimits = get(gca,'YLim'); set(gca,'YLim',[ylimits(1),ylimits(2)+0.2*max(y)]); % Increase y limit for labels
% Create labels to place over bars
labels = {'A', ['A';'B';'*'],'AB','',['A ';'**']}; for i = 1:length(x) % Loop over each bar
xpos = x(i); % Set x position for the text label
ypos = y(i) + ygap; % Set y position, including gap
htext = text(xpos,ypos,labels{i}); % Add text label
set(htext,'VerticalAlignment','bottom',... % Adjust properties 'HorizontalAlignment','center') endNote that if labels are desired for groups of bars, the x coordinates passed to the "text" function will need to be modified so that the text is placed over the correct bar. This can be done in a similar manner but taking into account that "hbar" in the above code is a vector of handles, and that the x and y coordinates of the text label must be adjusted for each group.
