When exporting as a pdf Float will use the date range that has been set up in the cash flow as the date range to export. So before exporting be sure to use the navigation shown above the graph to set up the relevant date range. Once done, hit the export button shown just above the graph and choose to export as a pdf.
This will generate a pdf copy that includes both the graph and cash flow table along with an overall summary showing the top line figures of cash in, cash out and net cash movement. For each cell in the table the pdf will show the higher of the budget and actual figure.
The other option is to export to .csv which you can check out here.
