Yield Values for the Eight Factor Combinations
Format the graph to see interval bars for Lower 95% Mean yield and Upper 95% Mean yield, and to see points for Pred Formula yield.
Confidence Limits and Means Plotted as Side-by-Side Bars
Interval Bar Style Applied to Three-Y-Axis Variables
The interval bar style currently spans from Lower 95% Mean yield to Pred Formula yield, but you want it to span up to Upper 95% Mean yield. Remove the bar element for Pred Formula yield.
Interval Span for Confidence Boundaries
Remove the point graph element for Lower 95% Mean yield and Upper 95% Mean yield.
