The 2D History map shows single-vehicle history with animation. Date choices include today, yesterday, week to-date, the past 7 days, month to-date, the past 30 days, or a custom range (no more than 31 days at a time).
Using the date selector: Click a selected day (one at a time) to clear it from the selection. To quickly clear a large selection of days, click the “T” option to select today’s date, and then click the highlighted date to de-select it. Start your custom selection again.
