How to Scatter Plot a data set reading from a single column of excel file?

I read a specific column of data from an excel file using following:

num = xlsread('newdata.xlsx', 'B:B');

While using plot(num), it works fine plotting a line graph where the x-axis is a continuous automatic value and y is the extracted column value. However, when I am trying scatter(num) it gives me Error. Isn't that possible to create scatter plot with a single column data please?

num = xlsread('newdata.xlsx', 'B:B');
x = 1:length(num) ;
scatter(x,num) ;
