Hi,
You can enable the ‘Statements’ chart in the Dashboard. You can filter by the date and then export the chart using the ‘Download chart’ icon on the top-right of the respective chart. Please refer the documentation, here.
You may refer the doc (at the bottom) for specifying the ‘Unit’ and the ‘Unit Factor’ to define the units, here. Please refer the image to edit the chart, here.
Regards,
Sibin
