Draw vertical lines on a plot
12 views (last 30 days)
I have a plot and I want to draw several vertical lines (about 40 of them) at specific locations on the plot. How do I go about it? Any code that I can put all those locations in and automatically mark those regions of the plot with vertical lines for me? Thanks!

There is a built-in function for that.
Here is sample code:
regions_to_be_marked = randn(40,1); % array of the points you want to plot vertical line (x axis values)
x_data = randn(100,1); % x data to plot
y_data = randn(100,1); % y data to plot
hFig = figure; % figure handle
hAxes = axes(hFig); % axis handle
hPlot = plot(hAxes,x_data,y_data,'LineStyle','none','Marker','*'); % your actual plot
hold on; % holds current plot
% plot each region in for loop
for i = 1:numel(regions_to_be_marked)
