‘datacursormode’ can be used to enable or disable data cursor mode.

For further information refer to the following link

sorry - it does not help

in the chart are more than one curve and may be therefor the datacursor does not work.

What can be done?

The code:

%% Visualize Data %%

yyaxis left;

plot(time1, data1,'o-', time, dewPoint,'+-','LineWidth', 1.4)

datacursormode on

% Click mouse on surface to display data cursor

yl = ylim;

ylim([yl(1)-0.5 yl(2)+0.5]);

ylabel('Temperatures [°C]');

yyaxis right

plot(time2, data2,'o-','Color','g','LineWidth', 1.4);

yl = ylim;

ylim([yl(1)-1 yl(2)+1]);

ylabel('rel. Humidity [%]');

xlabel('Date');

title('rel.Humidity + Temp. / DewPoint');

legend({'Temp.Tu','DewPoint','Humidity'},'Location', 'best');

grid on
