Yes, it’s possible to create data tips at the intersection points of the red line with the plots and display the legend and coordinates. Here’s how you can do it:
- Plot your data: You already have this part.
- Add the red line: Use the line function.
- Find intersection points: Use interpolation to find where the red line intersects the plots.
- Add data tips: Use the datatip function to add data tips at the intersection points.
x = 0:0.01:20;
y1 = 200*exp(-0.05*x).*sin(x);
y2 = 100*exp(-0.5*x).*sin(10*x);
figure;
hold on
p1 = plot(x, y1, 'DisplayName', 'data1');
p2 = plot(x, y2, 'DisplayName', 'data2');
legend('show');
% Add the red line
x_red = 10; % Example x-value for the red line
y_red = ylim;
red_line = line([x_red x_red], y_red, 'Color', 'red', 'LineWidth', 2);
% Find intersection points
y1_interp = interp1(x, y1, x_red);
y2_interp = interp1(x, y2, x_red);
% Add data tips
dt1 = datatip(p1, x_red, y1_interp);
dt1.Label = 'data1';
dt1.DataTipTemplate.DataTipRows(end+1) = dataTipTextRow('X', x_red);
dt1.DataTipTemplate.DataTipRows(end+1) = dataTipTextRow('Y', y1_interp);
dt2 = datatip(p2, x_red, y2_interp);
dt2.Label = 'data2';
dt2.DataTipTemplate.DataTipRows(end+1) = dataTipTextRow('X', x_red);
dt2.DataTipTemplate.DataTipRows(end+1) = dataTipTextRow('Y', y2_interp);

- The red line is added at x = 10.
- Intersection points are found using interp1. (https://www.mathworks.com/help/matlab/ref/interp1.html)
- Data tips are added at the intersection points with labels showing the legend and coordinates.
You can adjust the x_red value to place the red line at different x-values. This approach should help you distinguish between multiple plots even if their colors are similar.
