Q. How can I control how well a variable is resolved on a chart? I made two lines of different length and they indicated different values of pressure for a certain location on the line.
A. This is controlled during the definition of the line objects themselves by modifying the number of sample points. This is available in the as "Samples" under the Geometry tab when the object is created. By using, for example 50 points on a line 50 cm long, and then 83 points on a line 83 cm long, you ensure representations consistent between the two lines.
