Origin Ver. and Service Release (Select Help-->About Origin): OriginPro 2015
Operating System: Windows 7
I have multiple raw data sets that relate to a linear X from 0 -> 200 -> 0 -> -200 -> 0. The X points increase in increments of 2 (0, 2, 4, 6, etc) and the Y values are measured from an experiment so there is no equation or fitting there, just data. There are 401 points of data.
What I need is the same data but with another point in between each X point to make the spacing increments of 1, and for the Y data to be averaged or interpolated in some way that will keep the curve smooth.
I know there has to be a way to do this. But I am a rookie at any data manipulation more complicated than "smooth curve" and I can't figure out how to do it.
Thanks |

You can use Analysis: Mathematics: Trace Interpolation.
In the dialog, set the Recalculation Mode to Auto or Manual.
Unfortunately we can't set the increment of output X value.
But you can check Auto checkbox next to Number of Points and type the number of points you want to get. It should be roughly double the number of your input X.
If it's not incrementing by 1, you can single left click the green lock of the output columns and choose Change Parameters and change the Number of Points.
Thanks, Snow Li

Thanks Snowli.
I had tried that before but found that the X data was wildly wrong (somehow becoming incremented by about 0.4, which I don't understand mathematically)
BUT! The Y data is actually correct when I check it against my old data. So I can just replace out the X data with the right intervals.
Thanks again for your fix. |

Have data spaced increments of 2. Need incr of 1
