If you add new data to the end of the range (after 11/13), then Excel doesn't know you want those items added to the chart.
Instead, insert some blank rows somewhere within the data range; it doesn't matter where, as long as the record for 11/13 is below the added rows.
When the source data for your data-driven charts is available in Excel, you can create charts directly from the Excel application.
When data in Excel changes, you can either update the charts on command or have think-cell do the update automatically.
