DPlot

Newbie here. I need to create an XYY graph that shows data points with a moving average line on top od the points. Any suggestions?

Generate>Moving Average. That's an optional plugin module, so if you don't see it, just run the setup program again.

I guess I need to clarify a bit. The data contains 3 columns with over 200,000 points per column. When I do create a moving average its just a mass of squiggles. How can I clean that up so a single line shows the average? I have the a copy of the plot as it should be, the data and what I have been able to recreate. Any way I can send those graphs to you for review?

It sounds like you just need to use a larger bin size on the Moving Average.

You are welcome to send whatever files you have to support@dplot.com.

Just so anybody else reading this isn't confused, the poster's data was not sorted in X. So "Moving Average" produced a real mess: it doesn't care about sort order, it just works on existing data whatever order those points are in. Short answer is use Edit>Sort before Generate>Moving Average.
