Is there a way to disconnect lines between data points while utilizing the plot function?

조회 수: 150(최근 30일)
Let's say I have the following lines of code;
x = [1;2;3;4;5;6;7;8;6];
y = [10;20;30;40;50;60;70;80;30];
When executed, I get a simple 2D line plot where all 9 of the Y values are plotted and connected by a solid line.
Is there a way to disconnect the line between the 8th and 9th data point while maintaining it for the first 8?

plot([30 30.1 30.1 30.2 30.2 30.3 30.3 30.4 30.4 30.5 30.5 30.6 30.6 30.7], [-7 -7 -7 -7 -7 -7 -7 -7 -7 -7 -7.5 -7.5 -8 -8], 'k','LineStyle','--', 'linewidth',3, 'HandleVisibility','off')
i am using this methos but I would like to erase the drop lines. ideas how to do that

Dear Brad, you can do it the following way:
x = [1;2;3;4;5;6;7;8;9];
y = [10;20;30;40;50;60;70;80;90];
plot(x(1:end - 1),y(1:end - 1),'-o'); hold on
plot(x(end), y(end), 'o')
xlim([x(1) x(end)+x(1)]), ylim([y(1) y(end)+y(1)])
I hope it helps. Good luck!

God bless you however you are, i really had a good fight troubling with ploting points and after a lot of search none of those helped me, but this one saved me

Another way is to insert a NaN between the dis-connected points, such as:
x = [1;2;3;4;5;6;7;8;6];
y = [10;20;30;40;50;60;70;80;30];
x = [ x(1:8), NaN, x(9:end)];
y = [ y(1:8), NaN, y(9:end)];
Matlab won't plot a NaN, so the effect is to break up your lines.
