s = YourTable.signal_strength;
n = YourTable.hotspot_names;
x = ones(length(s), 1);
y = s(:);
scatter(x, y);
text(x, y, n);

x = 1 : length(s);
y = s(:);
scatter(x, y);
set(gca, 'XTick', x, 'XTickLabel', n);

How about using bar chart, like:
% Sample data
YourTable = table({'hotspot1';'hotspot2';'hotspot3'},[10;20;30],...
'VariableNames',{'Name','Value'});
bar(YourTable.Value);
ax = gca;
ax.XTickLabel = YourTable.Name;
