Drow the first Column of a particular matrix with specific colour and shape in MATLAB

Question

I have a matrix called All( that contains 36 Rows *36 Columns ). Each row in the first column represents the data of a specific user.
For Example: ( Row 1, Col 1) is the data of user1 (Row 2, Col 1 ) is the data of user2 and so on ...

while the remaining columns of each row represent the data of other users.

Here is an example

I'd like to draw the first column in the matrix with specific colour and shape and all the remaining column with another colour and shape in MATLAB or any other program that can do the purpose! .

The attached image is what I have done so far but I can't recognise the first column from other columns in the graph because all of them similar shape

You can use the function hold to retain current plot when adding new plots.

So if you have a Matrix M:

plot(M(:,1),'r^'); %plot the first column with red triangles
hold on
plot(M(:,2:end),'bo') %plot the next value with blue cirlces

Result:

All the details about line specification can be found here
