Where can I find the formula used to create a trend line in a chart?
Can I use the trend line formula to extract data for use elsewhere in a spreadsheet?
For example: I have a series of scattered data points (y=Area, x=Price). I want to be able to plug into a worksheet a new series of Area/Price data points using the data along the trend line.
This is my first time here and I will appreciate any help you can give!!
Welcome to the forum.
Right-click. Displaying the formula on the chart is an option for the trendline.
To get the parameters of the trensdline, you can use LINEST; see Help.
For details, you'd need to post a workbook.
Entia non sunt multiplicanda sine necessitate
LINEST appears to be what I need. Thank you for the quick reply.
