trend: boolean 'increasing' 'decreasing' Default: true Controls the direction of the digits. true: The digits go up if the number increases, and down if the number decreases. false: Ignores the trend of the number; each digit goes up if it increases and down if it decreases. This can be useful if you want to animate number changes without conveying an overall increase or decrease (example). "increasing": The digits always go up. "decreasing": The digits always go down.
