Trendline types in Excel
We can click on “Trendline” to list the different line options to use. To display all the options we can select any of the chart points, right-click and select “Add trendline” in order to display the Excel side menu associated with the trendline.
It is the default setting in Excel and is formed by a line that increases or decreases based on the data provided in the spreadsheet.
It is ideal when the data values increase based on the x values, there the exponential trend line offers a much more orderly view of the data.
It is a special logarithmic trendline for viewing the data as the rate of change decreases with increasing x-values.
It is ideal where the data has an upward and downward trend based on wave patterns and its design allows you to see the number of curves in the graph either up or down. Note that the “Degree” field is available in which we can define the curve.
Applies where data tends to increase frequently.
It is an ideal trendline in cases where the data is highly variable, as it takes an average since this line will take the average of every two points in the given graph.
How to add a trendline and R squared value in the chart in Excel?
At the bottom of the trendline options, we find a checkbox called “Show R-squared value on chart” which will display the R-value. This is a measure that indicates the distance of each point on the trend chart, so the closer the R-squared value is to each other, the better the lines will fit the trend data. By checking this box we see the line with the R-squared value in the selected chart.

Extrapolation is synonymous with the forecast in the data, there we have the options “In the future” and “In the past” and they are measured in periods, so we can define how many periods in the future to apply and the trend line will do the rest.
