DPlot

if you have numbers like this


X Y
29 100300
34 90270
38 80240
45 70340


the program gives doesn't give you a perfect parabool but you want the most accurate cause you're numbers aren't exact hon can you do this

I'm sorry but I don't understand your question. If you want a smoother curve rather than straight line segments between those points you have a couple of options:

• Generate>Polynomial Curve Fit (or "More Curve Fits" with the licensed version) and specify a large number of points in the fitted curve. You'll still get straight line segments, of course, but with a much smaller spacing between points the curve will appear to be smooth.
• Edit>Equal Intervals with Cubic Spline selected and a small interval - say 0.001 or so. Same qualifier as above applies: You'll still get straight line segments, but it will appear smooth.

If I've completely misunderstood your question please let me know.
