Converting Timestamp to double data

[Runjhun]

Hi,

I'm plotting a bar graph which takes only double data input.

My X-axis should be the timestamp and my Y-axis is the double data.

Bt here I can't figure out any way to convert the timestamp to double so that I can use it as an input.

Any suggestions.

Regards,

I had thought that timestamps readily coerce to doubles, but it seems that using the To Double Precision Float primitive is necessary.

I have used that but its not giving me the required output. If I convert it in this way then its giving me the time elapsed since 1.1.1904 till today. I dnt want this value to be seen as a plot to my graph. Without the change in the values the timestamp should be converted to double.Becoz i am feeding this input to the Excel Plot Graph function which accepts X-axis and Y-axis values in a Double 2-d array.

If you want relative time ( your first X point = 0) you will need to subtract the timestamp value of the first X data point from every successive data point's timestamp.

Subtracting one LabVIEW timestamp from another will result in a double precision value with a unit of seconds.
