bar function not working
显示 更早的评论
Im new to MatLab and am using pre-existing code to perform a simple task of making a bar chart. Im getting an error message that says, "Must supply Y data or X and Y data as first argument(s)."
My code:
figure
[sort,I]=sortrows('lastoil',-1);
bar(sort);
My variables are defined in this picture below. What am I doing wrong?

Don't use sort as a variable name - it's a built-in function. Call it sortedValues. ALso, pass it some data (lastoil), not a string ('lastoil').
[sortedValues, sortOrder] = sortrows(lastoil, -1);
bar(sortedValues, 'FaceColor', 'b', 'BarWidth', 1);
grid on;
