This is a nice and unique way to show a conceptual upward trend (or backward trend if you flip the trend graphic horizontally). The callout lines provide opportunities to add notes to points on the trend ramp. you may need to adjust/add/delete the leader lines for the callouts, but it is as simple as copy/delete, spacing the callout leader lines horizontally, and then adjusting the vertical height by pulling the sizing handle up or down. If you wish, you can use your own leader lines to make it simpler.
