You can further customize your trend line by adjusting the color, thickness, and forecast options. Right-clicking a data point brings up a context menu that allows you to add a trend line. Go to the “Insert” tab and select the type of graph you want, such as a line or scatter plot. Data extrapolation estimates values beyond the known data points based on the assumption the trend of the data continues. The monthly sales dataset contains the month no., Month, east region, west region, central region, and total units sold from columns A through F. For more information, please see How to add a trendline in Excel.
Alternatively, you can click the Chart Elements button, then click the arrow next to Trendline and choose the type you want. Excel will show a list of the data series plotted in your chart. A trendline can be added to a variety of Excel charts, including XY scatter, bubble, stock, as well as unstacked 2-D bar, column, area and line graphs. Visually, a trendline looks somewhat similar to a line chart, but it doesn’t connect the actual data points as a line chart does. A best-fit line shows the general trend in all the data, ignoring statistical errors and minor exceptions. When plotting data in a graph, you may often want to visualize the general trend in your data.

Adding a trend line in Excel is just the tip of the iceberg when it comes to the powerful data analysis tools at your disposal. After you complete these steps, your Excel graph will display the trend line, making it easier to understand the direction your data is heading.
Step 3: Add a trend line
In your real worksheets, you should choose the trendline type corresponding to your data type. This trendline type is often used in sciences, for example to visualize a human population growth or decline in wildlife populations. No, trend lines cannot be added directly to pivot tables in Excel. However, you can create a chart from a pivot table and add a trend line to the chart. The equation displayed on an Excel chart is correct only for XY scatter plots. For more information, please see Why Excel trendline equation is wrong.
Add, Manage, & Remove Trendlines in Charts in Excel
Before we dive into the technicalities of adding trend lines in Excel, let’s clarify what they are. A trend line is a straight or curved line that serves as a visual representation of the general direction or trend in data points plotted on a chart. The trendline formulas should only be used with XY scatter charts because only this chart plots both x and y axes as numeric values.
Method 4 – Utilizing a Line Chart with Excel Shapes to Create a Trend Chart
To predict a trend for the future, you just need to include a set of new x-values in your TREND formula. Supposing you are analyzing some data for a sequential period of time and you want to spot a trend trend lines in excel or pattern. Additionally, the TREND function can extend the trendline into the future to project dependent y-values for a set of new x-values.
Finally, I’ll also present to you programmatic approaches to create trendlines in Excel. A linear trendline is a straight line that represents the general trend of data points in a graph. It’s particularly useful when you have data that follows a relatively straight and consistent pattern. By adding a trendline to your graph, you can make it easier for your audience to understand the overall trend and make informed decisions based on the data. The “Moving Average” trendline shows the trend of the average of a specific number of periods.
Once you’ve created your chart, you can add a trend line in a few simple steps. The first thing you need to do is open your Excel spreadsheet and select the data you want to chart. Make sure your data has column headers so that Excel can recognize them. The Trend Line in Excel is a line that provides a visual representation of the trend of the given dataset.
In the first example, the line graph had only one data series, but the following column chart has two. You can now choose the second data series in the dialog box to add the second trendline. If there’s only one data series in your chart, Excel shall instantly add the trendline to the graph. Exponential lines are curved lines suitable for data that rises or falls at an increasing rate. Polynomial lines are used for more complex data sets with multiple peaks and valleys.
Change the Color and Width of the Trendline
For example, we can add a trendline to a column chart, line chart, bar chart, scattered chart or XY chart, stock chart, or . No, trend lines can only be added to scatter plot charts, line charts, and a few other chart types in Excel. To add trendlines for different series like that in an Excel chart, you need to select them individually before inserting a trendline.
Trendlines allow you to show trends in charts that might be otherwise difficult to notice. Basically, this is mostly used as a visual aid to illustrate an upward, downward, or flat trend over varying data points in a chart. Read all about it here or dive into linear regression specifically. Select one data series at a time and follow the steps of the above example. A trendline, also referred to as a line of best fit, is a straight or curved line in a chart that shows the general pattern or overall direction of the data. Multiple trendlines in a single chart can highlight both short and long-term trends.
- While trendlines are most commonly used with scatter plots, you can also add them to other types of graphs, such as line charts.
- Right-click on the trend line you want to remove and select “Delete.” It’s that simple.
- In this example, the R-squared value equals 0.957, which means that the trendline fits about 95% of data values.
- You can customize the look of the trendline in many ways to make the trendline easily readable, informative, and professional.
Extrapolate a Nonlinear Graph in Excel
It’ll guide you through the trendline-adding process visually. To make the best use of a trendline and extract actionable data insights, you must use the right type of trendline for the given dataset. There, you can customize the following attributes of the trendline. I’ve also mentioned the parent menu where you’ll find the options listed below. In the current exercise, I’ve shown the usage of Forward Forecast in Excel trendlines.
If you are looking for how to insert a trendline in an Excel chart, please check out the above linked tutorial. Excel offers various types of trendlines, including linear, exponential, logarithmic, and polynomial. In this guide, we will focus specifically on inserting a straight line, or a linear trendline, as it is the most commonly used and appropriate for many types of data. This script will automatically add trendlines to all the data series of the selected chart.
Excel FORECAST vs TREND
- This representation can be conveyed through column charts, line charts, scatter charts, and so forth.
- The first thing you need to do is open your Excel spreadsheet and select the data you want to chart.
- You will notice the mathematical equation that appears to the right of the Trendline.
- In the following example, I changed the color to orange, so it’s different from the column color.
- For consistency, we will be using the same data set with slightly varying values for all the examples.
You can calculate moving average manually with your own formulas or have Excel make a trendline for you automatically. To show the trendline equation, check the Display Equation on chart box. For better accuracy, you can show more digits in the trendline equation.
