If you want data between those times, that's where life gets tricky. In the probe function, probing at a location where no data but the line between points occurs, the probe function generally uses weighted averaging to obtain the data if the linear curve option is active (default). If you want something more smooth, you can change the curve type to a polynomial and then output the coefficients or equation that recreates the line. This does not necessarily prevent over or under shooting the data. You can also use an integration method of your own to interpolate the data. I typically use an Akima style spline because it is better behaved through data and produces the least over/under shoots between known data points. In that mode, you can write a macro that takes the known data points and generates the additional locations or specific locations between known data.
Basically, you either use a function built-in Tecplot to generate a continuous line, or implement one yourself with a macro.
Hope this helps.
