Problem adding labels to figure

I am trying to make a figure but when I give the values to the label they are not reflected on the figure. My vector in the X axis was named as x3, however these values are not reflected in the graph. How should I proceed to do this? Thank you very much.

fig=figure(3);
clf;
x3=[Bicicleta; Microbus; Motocicleta; Vehiculo; Tractocamion];

Unrecognized function or variable 'Bicicleta'.

y3 = [1 1 1; 219 65 4; 300 828 36; 986 250 10; 0 0 10];
b3=bar(x3,y3);
ylim([0 1100])
xtips3 = b3(1).XEndPoints;
ytips3 = b3(1).YEndPoints;
labels3 = string(b3(1).YData);
text(xtips3,ytips3,labels3,'HorizontalAlignment','center',...
    'VerticalAlignment','bottom')
xtips3 = b3(2).XEndPoints;
ytips3 = b3(2).YEndPoints;
labels3 = string(b3(2).YData);
text(xtips3,ytips3,labels3,'HorizontalAlignment','center',...
    'VerticalAlignment','bottom')
xtips3 = b3(3).XEndPoints;
ytips3 = b3(3).YEndPoints;
labels3 = string(b3(3).YData);
text(xtips3,ytips3,labels3,'HorizontalAlignment','center',...
    'VerticalAlignment','bottom')
legend('Accidente','Lesionado','Muerte')
xlabel("Agente causante");
ylabel("Número de agentes");

Running your code produces errors (see above). Please post sufficient code so that it can be run in the forum and the problem reproduced.

Matt J muchas gracias ya pude correr el codigo. un saludo muy grande.

One problem is that just after creating the figure the code clears it.

Otherwise perhaps something like this —

fig=figure(3);
% clf;
x3=categorical(["Bicicleta"; "Microbus"; "Motocicleta"; "Vehiculo"; "Tractocamion"]);
y3 = [1 1 1; 219 65 4; 300 828 36; 986 250 10; 0 0 10];
b3=bar(x3,y3);
ylim([0 1100])
xtips3 = b3(1).XEndPoints;
ytips3 = b3(1).YEndPoints;
labels3 = string(b3(1).YData);
text(xtips3,ytips3,labels3,'HorizontalAlignment','center',...
    'VerticalAlignment','bottom')
xtips3 = b3(2).XEndPoints;
ytips3 = b3(2).YEndPoints;
labels3 = string(b3(2).YData);
text(xtips3,ytips3,labels3,'HorizontalAlignment','center',...
    'VerticalAlignment','bottom')
xtips3 = b3(3).XEndPoints;
ytips3 = b3(3).YEndPoints;
labels3 = string(b3(3).YData);
text(xtips3,ytips3,labels3,'HorizontalAlignment','center',...
    'VerticalAlignment','bottom')
legend('Accidente','Lesionado','Muerte', 'Location','NW')
xlabel("Agente causante");
ylabel("Número de agentes");

See the documentation for string and categorical for details on them.

Thank you very much, one last question, how can I convert the graphic to grayscale? So that it looks like this figure attached as an example.

Thank you for your attention.

As always, my pleasure!

One option —

fig=figure(3);
% clf;
x3=categorical(["Bicicleta"; "Microbus"; "Motocicleta"; "Vehiculo"; "Tractocamion"]);
y3 = [1 1 1; 219 65 4; 300 828 36; 986 250 10; 0 0 10];
b3=bar(x3,y3, 'FaceColor','flat');                          % Set 'FaceColor' To 'flat'
cm = gray(5);                                               % Define 'colormap'
for k = 1:numel(b3)
    b3(k).CData = cm(k+1,:);                                % Loop To Set Colours
end
ylim([0 1100])
xtips3 = b3(1).XEndPoints;
ytips3 = b3(1).YEndPoints;
labels3 = string(b3(1).YData);
text(xtips3,ytips3,labels3,'HorizontalAlignment','center',...
    'VerticalAlignment','bottom')
xtips3 = b3(2).XEndPoints;
ytips3 = b3(2).YEndPoints;
labels3 = string(b3(2).YData);
text(xtips3,ytips3,labels3,'HorizontalAlignment','center',...
    'VerticalAlignment','bottom')
xtips3 = b3(3).XEndPoints;
ytips3 = b3(3).YEndPoints;
labels3 = string(b3(3).YData);
text(xtips3,ytips3,labels3,'HorizontalAlignment','center',...
    'VerticalAlignment','bottom')
legend('Accidente','Lesionado','Muerte', 'Location','NW')
xlabel("Agente causante");
ylabel("Número de agentes");

In order to avoid the colormap ‘extreme values’ (black and white at both ends for the gray colormap), I returned five colours and used the centre three, since that most closely approximates your posted plot image. (This approach uses a variation of the one described in Bar Chart with Colormap Colors.)
