In excel you have an option to add polynomial trendline. You can add second order or third order polynomial tren.. Polynomial: A polynomial trendline is also a curved line used to visualize data fluctuations. The fluctuations are seen as a hill or valley in the trendline. Power: A power trendline is another curve line used with data sets comparing values that increase at a specific rate. This trendline is only possible for positive values Typically, a quadratic polynomial trendline has one bend (hill or valley), a cubic polynomial has 1 or 2 bends, and a quartic polynomial has up to 3 bends. When adding a polynomial trendline in an Excel chart, you specify the degree by typing the corresponding number in the Order box on the Format Trendline pane, which is 2 by default

Step 2: Add a trendline. Next, we need to add a trendline to the scatterplot. To do so, click on any of the individual points in the scatterplot. Then, right click and select Add Trendline A new window will pop up with the option to specify a trendline. Choose Polynomial and choose the number you'd like to use for Order. We will use 3. Argument. Settings. Type. An xlTrendlineType constant indicating how the trendline is calculated. Can be one of these settings: xlExponential, xlLinear (default), xlLogarithmic, xlMovingAvg, xlPolynomial, or xlPower. Order. For polynomial trendlines, the trendline order from 2 to 6. Period. For moving average trendlines, the number of data points to include in the average I am using Office Excel 2016, there is a bug in the Polynomial (and possibly other trendline) formula displayed in the chart whereby y = c2.x2+c1.x+b is displayed as y = c2.x2-c1.x+b. The addition sign is wrongly displayed as subtraction. - BenP Mar 26 '19 at 11:0

Polynomial - Curved line that is used when data fluctuates. Useful for analysing gains and losses over a large data set. The order of the polynomial can be determined by the number of fluctuations in the data or by how many bends (hills and valleys) appear in the curve. An Order 2 polynomial trend line generally has only one hill or valley Iď¸Ź read an earlier thread with this same problem but the solution (run updates) does not apply to me because my Excel is current.

1. I'm using excel for convenience. The data are curvilinear and I'm adding a polynomial trendline to maximize the fit. The problem I have is that the trendline function seems to assume that the x values are 1, 2, 3 and so on. Although in my graph they are actually 0, 0.1, 0.2, and so on. The resulting trendline equation thus does not make much sense
2.
