I believe you can manually import new data in to an existing chart using .csv data. You would need to specify the time stamp value as a stand C time_t data type.
Other than absolute humidity, are you trying to chart other data?
As an alternative you could have WUHU write CSV data, import that to Excel, and implement the formula in a spreadsheet. That works but I also like Teechart's ability to zoom and pan.
