Why am I getting "Invalid first data argument"

Question

0 个投票

I am trying to plot the following.

s = {Fun_WS1; Fun_WS2; Fun_WS3; Fun_WS4; Fun_WS5; Fun_WS6; Fun_WS7; Fun_WS8; Fun_WS9; Fun_WS10};
h=[0:10];
semilogy(s,h);

I have all the Fun_WS values defined in the workspace (shown in the attached .PNG).

Why am I getting "Invalid first data argument"?

Try this:

s = [Fun_WS1; Fun_WS2; Fun_WS3; Fun_WS4; Fun_WS5; Fun_WS6; Fun_WS7; Fun_WS8; Fun_WS9; Fun_WS10];
h=[1:10];
semilogy(s,h)

Using a cell array here is inappropriate. Use a regular vector instead. Also, ‘s’ has 10 elements, ‘h’ originally had 11. I corrected that.

NOTE — Since I do not have your original data, only the image, this is UNTESTED CODE. It should work.
