how to show two different plots with current system time and date on waveform chart

[mom]

I am using  one waveform chart to display the more than one value continiously. The data  are comming properly but i am not getting my system (pc) time and date on x axis. It is showing default date and time (i.e.01/01/1904 5:30:45). Please  give me suggestions to display the real time and date on x axis of waveform chart.

How does your data look like? Do you graph waveform data types, dynamic data, or plain arrays/clustes? In the case of plain arrays, you need to set x0 to the absolute start time of your data, e.g. with a property node.

I you would attach your code (or an image) we could offer more specific advice. There are too many possibilities. 😉
