Graphing Tendline - Chart Director

I am currently trying to graph a trendline to the scatterplot data on the chart I produced using Chart Director. The formula for calculating this trend line is already implemented to give me the slope and y-intercept.

Is there a means to put this data into y=mx+b (m=slope, b=y-intercept) format or something similar to produce a line?

Thank you so much!

you can calculate x/y values and add a line layer on top to draw it.

Is there a means to draw the line across the entire charting area based off of calculating the lowest and highest x-axis and y-axis values?

well, you can use a line layer to draw it. So you don’t need to draw it yourself.
