I have a straight reference line in graph, but can I have a polynomial reference line like below?
Y=pow(10,2)*X+pow(5,-2)*X^2+1.2
You cannot specify the formula, but it is possible to add polynomial trendlines to a measure in your line chart, maybe that will work?
It looks like the (dimesnional) reference lines can only be horizontal or vertical lines.
Please like and mark my answer as a solution, if it resolved your issue.
thank you.
Is it possible to draw a straight line polynomial on a scatterplot?
I thought about using a combo chart, but I want to use a scatter chart because what I want is a chart that requires 2 axes and 1 measure.
Under add-ons in the properties panel, there is an option to add a (linear) Regression line. Try that!
Thank you very much.
I don't want to draw a regression line.
I want to plot a polynomial function that has nothing to do with the plotted points.
Is it impossible to draw...?
