Export/Copy Plot Line Values

I need to be able to copy the values of a line from my plot. I know that the line is saved as a 1x70 vector in the workspace, but is there a function to copy these numbers to the clipboard. I ultimately want to use this function in the app designer, so saving directly from the workspace isn't ideal.

Try siomething like this —

x = 0:10;
y1 = x.^2;
y2 = 50*sin(2*pi*x/10)+50;

figure
hp = plot(x, y1,  x, y2);

Line1X = hp(1).XData

Line1X = 1×11

0 1 2 3 4 5 6 7 8 9 10

Line1Y = hp(1).YData

Line1Y = 1×11

0 1 4 9 16 25 36 49 64 81 100

Line2X = hp(2).XData

Line2X = 1×11

0 1 2 3 4 5 6 7 8 9 10

Line2Y = hp(2).YData

Line2Y = 1×11

50.0000 79.3893 97.5528 97.5528 79.3893 50.0000 20.6107 2.4472 2.4472 20.6107 50.0000

What function can I use to copy each of these values to a system clipboard to export them as a excel type array?

[Star Strider]

I doubt that there is a specific function for that. You would likely have to do something like this —

x = 0:10;
y1 = x.^2;
y2 = 50*sin(2*pi*x/10)+50;

figure
hp = plot(x, y1,  x, y2);

Line1X = hp(1).XData.';
Line1Y = hp(1).YData.';
Line2X = hp(2).XData.';
Line2Y = hp(2).YData.';

T1 = table(Line1X, Line1Y, Line2X, Line2Y)

T1 = 11×4 table
    Line1X    Line1Y    Line2X    Line2Y
    ______    ______    ______    ______

       0         0         0          50
       1         1         1      79.389
       2         4         2      97.553
       3         9         3      97.553
       4        16         4      79.389
       5        25         5          50
       6        36         6      20.611
       7        49         7      2.4472
       8        64         8      2.4472
       9        81         9      20.611
      10       100        10          50

writetable(T1,'YourFileName.xlsx')
