How do you create a curve graph in Excel 2007?
Select and highlight the range A1:F2 and then click Insert > Line or Area Chart > Line. The line graph is inserted with straight lines corresponding to each data point. To edit this to a curved line, right-click the data series and then select the “Format Data Series” button from the pop-up menu.

What is a curved graph called?
The formal term to describe a straight line graph is linear, whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship. Similarly, the relationship shown by a curved graph is called non-linear.
What does a polynomial curve show?
A polynomial trendline is a curved line that is used when data fluctuates. It is useful, for example, for analyzing 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.
What do you mean by curve fitting?
Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints.
What does Logest formula in Excel?
In regression analysis, the LOGEST function calculates an exponential curve that fits your data and returns an array of values that describes the curve. Because this function returns an array of values, it must be entered as an array formula. Excel inserts curly brackets at the beginning and end of the formula for you.
What is a polynomial curve?
Polynomial Curve. A curve obtained by fitting polynomials to each ordinate of an ordered sequence of points. The above plots show polynomial curves where the order of the fitting polynomial varies from to, where is the number of points.
When to use polynomial Trendline?
A polynomial trendline is a curved line that is used when data fluctuates. It is useful, for example, for analyzing gains and losses over a large data set.
What is a polynomial trend?
Polynomial trending describes a pattern in the data that is curved or breaks from a straight linear trend. It often occurs in a large set of data that contains many fluctuations. As more data becomes available, the trends often become less linear, and a polynomial trend takes its place.
