Runjhun 1 Report post Posted October 11, 2011 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, Runjhun A. Quote Share this post Link to post Share on other sites
asbo 156 Report post Posted October 11, 2011 I had thought that timestamps readily coerce to doubles, but it seems that using the To Double Precision Float primitive is necessary. Quote Share this post Link to post Share on other sites
Runjhun 1 Report post Posted October 12, 2011 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.

Phillip Brooks 189 Report post Posted October 12, 2011 (edited) 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.
