how to plot negative and positive time axis programmatically?

[LV_Enthu]

Hello All,

I have a program where in I would like to display both the positive and negative time-axis.. basically, i will generate a sample (peak value of a signal), consider that as zero time, and plot RELATIVE negative and 

positive time axis wrt the peak sample value... 

Can anyone please suggest me any ideas?

What is the format for the source of your data? Do you have absolute time values, relative time values, or a single timestamp for where the peak is? Do you have a waveform datatype? Arrays? Please provide details.

smercurio_fc, the data file is an output from DAQmx, AI waveform data-type.. I basically have to select 1 of the 5 channels being sampled, find its peak, and that peak value is the new zero for the graph to be plotted... 

I am writing a relative time to the data-file and reading the same, 

below is a screen shot of the sample data file, 1st column is the time-stamp, sampling freq is 20KHz... Attached is the sample vi i have made till now... I have generated a peak vale from channel 3, and plotted channel 5 wrt to the sample-time of channel 3 peak... this is waht i intend to do actually... 

I am using read from measurement file to read the file format below.
