long_pos.mat

Hi

I have attached the timeseries data ("long_pos.mat") which I plotted to get to get the following figure.

I want to get the plot within ylim [0 600] and without the vertical lines(which are generated due to -150 values in the timeseries data). Can someone kindly help me with this? Thank you.

Here is the solution

load long_pos.mat
Y = simout_x.Data; % extract data
T = simout_x.Time; % extract time
Y(Y<0) = nan;      % replace negative values with 'NaN'
plot(T,Y);

long_pos.mat

Try this:

s = load('long_pos.mat')
simout_x = s.simout_x;
tsInfo = get(simout_x)
data = simout_x.Data;
% Replace -150 with nan so it won't plot.
data(data == -150) = nan;
t = simout_x.Time
for col = 1 : size(data, 2)
	plot(t, data(:, col), '-', 'LineWidth', 2);
	hold on;
end
xlabel('t', 'FontSize', 15);
ylabel('y', 'FontSize', 15);
ylim([0, 600]);
grid on
