The attached image is an Excel chart I created (for my daughter's research data) based on 4 time series (plotted as points, no need to identify as separate entities) the blue curve is something I drew in, but it represents a cubic function (as created in SPSS with the same data). She prefers the appearance of Excel to SPSS but would like the blue line plotted not drawn. The cubic function equation is
53.8538929166713 + 46.64544988975923 * x +
-10.05852960664259 * x*x + 0.5421132687450991 * x*x*x
Can anyone advise on how I might introduce this to the chart:banghead: I can upload the worksheet if needed. Stan
