# Call Center by Skill Calls Handling The top pie chart shows the proportion of the total number of ACD calls that were offered to each of the selected ACD Skills between the date and time range you entered in the chart options panel. The bottom stacked bar chart shows the averages of Queue, ring, conversation (talk) and wrap-up time for each of the ACD Skill you selected in the chart options panel. As with all charts, hover the mouse over a slice or column for more detail about that particular data. The chart data can be exported to XSLX format using the export icon at the bottom of the page and individual data series in the bar chart can be turned off or on by clicking the series legend on the right side of the chart.
