I have already opened a figure and i want to plot a new figure without being in the old one. For that purpose I want to display the x axis as matrix(:,1) and the y axis as matrix(:4). At the same time I want a vertical dotted line in the new figure when the x axis is a multiple of 60 (60, 120, 180 ....). How will I plot that chart?

x = matrix(:,1);
y = matrix(:,4);
plot(x, y);
maxx = max(x);
maxx = 60 * ceil(maxx/60);
xticks = 0 : maxx;
set(gca, 'xtick', xticks, 'xgrid', 'on', 'gridlinestyle', ':')
