GraphicsRe: How to draw a trapezoid inside Fit Y by X chart or graph builder?Sorry, I do not know off hand, so I'll let others chime in. What is the criteria you want to use to create the trapezoid? What do you want this?Re: How to draw a trapezoid inside Fit Y by X chart or graph builder?Hi,
Could you confirm that you are looking for a method to calculate the anchor points of your trapezoid and not just a method to draw the trapezoid which can be easily done with the Polygon () function? If it is the case, what are the criteria for the desired dimensions of your trapezoid (i.e. anchor point positions)?
Best,
