If you’re wondering how to add trend lines to a chart in Excel, this article will help you out. There are many types of trend lines, including Linear, Polynomial, and Power. You can also apply different kinds of special effects to your trendline. Let’s get started. First, open the Format Trendline pane. Click on “Fill & Line,” and then click on “Effects.” In the Effects tab, you can add various special effects to your trendline. Lastly, select the “Trendline Options” tab, which is symbolized by a bar graph.
Logarithmic trendline
A Logarithmic trendline is a curved trendline that is calculated using the least-squares method. The user can add this trendline to a chart by pressing the arrow on the “Trendline” tab, then selecting the radio button for “Logarithmic.” Once the trendline is added to a chart, double-click on it to open the settings pane. There, a user can toggle whether they want the equation to be displayed on the chart or not.
In Excel, a logarithmic trendline shows values that are increasing or decreasing. It can also be used to depict data values that are positive or negative. A logarithmic trendline can be used in different scenarios. The following is a brief overview of the various types of trendlines that you can use in Excel. It can help you to understand which type of trendline will be most useful for your data.

Polynomial trendline
You can use the polynomial trendline in Excel to draw a graph. The polynomial trendline is a best-fit line, which means it is derived from an equation that has multiple powers of x. The higher the power of the polynomial, the better, as the results are more unpredictable. The R value represents how well the equation fits the existing data. You can insert a Chart and trendline into your graph to see how it moves over time.
Using a polynomial trendline is an effective way to create a chart that compares the x-axis values with those on the y-axis. The LINEST function returns the coefficients of x, y-intercept, and x 2. The results are the same as those generated with the chart trendline tool. The coefficients are stored in cells and are calculated using a formula that takes the highest order of the independent variable into account.
Power trendline
A power trendline is a curved line that represents an increasing rate. It is useful for plotting data such as product sales or profit. It cannot be used on negative or zero values, which makes it useful for measuring chemical reactions. Its R-squared value is 0.9923.
Power trendlines are best for data that is increasing or accelerating. The trendlines also display the R-squared value, which measures how far each point is from the trendline. The closer the R-squared value is to 1, the better the trendline. If you’re curious how to add a power trendline to your spreadsheet, here’s how. You can also display the R-squared value on your chart.
If you’d like to display multiple trendlines with the same color and style, you can use the moving average. This helps to smooth out data that fluctuates wildly and shows a clear direction. Once you’ve created a power trendline, you can further customize its appearance by changing the color, transparency, width, dash type, and cap type. To format a power trendline in Excel, simply right-click on it and select Format > Trendline
Linear trendline
If you want to display the general upward trend in a graph, a linear regression trendline is a must-have feature for your next project. Unlike an average line graph, it does not overlap data points. This feature also requires proper formatting for a more legible graph. To add a trendline to your chart, open the Format Trendline window. Once you’ve chosen your style, click OK.
To add a linear trendline to your chart, click the plus icon of a data series. This will open a submenu. Click the Trendline Options tab to see the various types of trendlines available in Excel. To format the trendline, select the style that matches your overall design. In addition, you can customize the style of your trendline to match your chart’s style. This is a simple way to add a trendline to your chart
