Are there non-linear trend-line options for the scatter plot chart in ArcGIS Pro? I currently use Excel to plot data and I use the Power trendline option to generate an equation like y = mX ^ b with an associated R-squared. Is it possible to generate this trendline directly in ArcGIS Pro?

linear and logarithm axes are supported

you can transform the data yourself and use a linear axis if you the power trend to use and you don't like logarithmic or it doesn't fit

HI @BenRomlein ,

Thanks for the question. Scatter plots currently only support linear trend lines, but adding other options is in our near-term plan. 

Take care,

Chris

Thanks for the replies. I was able to write a geoprocessing script to accomplish what I needed to do using scipy.optimize.curve_fit and matplotlib.pyplot
