Stop line after intersection with other line

조회 수: 31(최근 30일)
Hello all,
I am trying to figure out how to do this seamingly simple operation easily. I am plotting some ylines and corresponding xlines using interp1 in order to essentially create "crosshairs" at some point. Ideally, only the part of the lines going from an axis to the main line would be showing, not the portions above or to the right. Can anyone think of a simple way to do this? Thanks

I am not certain what you want. If you want lines to only go an intersection of another line, try something like this —
x = linspace(0, 60);
y = @(x) 20*x; % Equation of Blue Line
plot(x, y(x), '-b', 'LineWidth',2.5)
hold on
x1 = 27;
plot([1 1]*x1, [0 y(x1)], '--g')
plot([0 x1], [1 1]*y(x1), '--r')
hold off
Make appropriate changes to get the result you want for the other lines. Iv you have a vector of independent variable values, consider using a loop.
