Hi,

There are lots of people asking this question but there is never an answer that works. I have a non linear scatter plot. I want to find some y values for given x values from the plot. A trend line will not work. Ananlysing exisiting data will not work, I want to read from the chart.

I have a little example attached.

I want to use 10 values to plot a curved scatter plot chart, then create a list of y values from given x values to plot another chart, this time a linear chart to see if it close to the curved one..... The second chart will be many x values evenly spaced to try to simulate the original curve using small straight lines.

I think FEvaluate_Bezier is possibly the answer but I am having problems applying it.

Any help would be great, thank you....
