So in my attached sample, you'll see the lowest bucket says "303" which is a "Bind" as you see in my legend. My question is why does the text box I made and overlayed on the brown bucket say 303 but the legend says Null? Its the exact same expression.
And they show the same number to start, until I make any sort of selection to aggregate the data such as a list box with a list of States. Then the textbox will show the correct number but the chart legend will move to Null
