I am making a box and whisker graph. I have taken the differences between the min, q1, med, q3 and max. I noticed that I was able to add error bars just fine when I had two sets of these differences but when I only have one set it does not work. Even though I click the error bars check box, the error bars do not show up.

As you can see on the screenshot I have the error bars working for the chart with 2 sets of data, but not the one with only one set (on the left).
Please help me, I do not know how to fix this
