style=\"font-weight: 400\">You might have known that visualization is an important part of data analysis. For a visually inclined person, it&#8217;s hard to understand data without<\/span> <a href=\"https:\/\/www.fusioncharts.com\/blog\/15-things-you-should-know-about-google-charts-alternatives\/\" target=\"_blank\" rel=\"noopener\"><i><span style=\"font-weight: 400\">charts and graphs<\/span><\/i><\/a><span style=\"font-weight: 400\">. And for those who want to analyze data more effectively, trendlines can be a very helpful tool.<\/span>\r\n\r\n<span style=\"font-weight: 400\">When using visualizations in Google Sheets, you can add trendlines to illustrate the direction of a data series. Trendlines are a helpful tool for completing the picture for that data series and simplifying chart analysis. Adding multiple trendlines can help identify patterns in your data.<\/span>\r\n\r\n<span style=\"font-weight: 400\">&#8216;Line of best fit&#8217; or &#8216;trendlines&#8217; are superimposed on a chart to show the trend of the data. They are also used to identify turning points and to identify possible market bottoms and tops. Not only can trendlines be used to understand <\/span><i><span style=\"font-weight: 400\">charts<\/span><\/i><span style=\"font-weight: 400\">, but they can also make predictions about future market movements and identify the relationships between data points.<\/span>\r\n\r\n<span style=\"font-weight: 400\">As a charting tool, your charts will look better and be more informative if you add trendlines. This is because trendlines help visually identify patterns in the data and can help to highlight important turning points.<\/span>\r\n<h2><span class=\"ez-toc-section\" id=\"How_To_Add_Trendlines_To_A_Chart_In_Google_Sheets\"><\/span><b>How To Add Trendlines To A Chart In Google Sheets?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<span style=\"font-weight: 400\">Before I show you how to add a line of best fit, let us first quickly go over how you can create a chart for the data shown below:<\/span>\r\n<h3><span class=\"ez-toc-section\" id=\"Creating_A_Scatter_Chart_In_Google_Sheets\"><\/span><b>Creating A Scatter Chart In Google Sheets<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<span style=\"font-weight: 400\">To create a scatter chart, simply select the data you want to plot, and then use the <\/span><b>scatter function<\/b><span style=\"font-weight: 400\"> in Google Sheets. Pick the <\/span><b>data range<\/b><span style=\"font-weight: 400\">, the <\/span><b>chart type<\/b><span style=\"font-weight: 400\">, and the <\/span><b>data point type<\/b><span style=\"font-weight: 400\">.<\/span>\r\n\r\n<span style=\"font-weight: 400\">Click <\/span><b>Insert <\/b><span style=\"font-weight: 400\">and then click <\/span><b>Chart<\/b><span style=\"font-weight: 400\">. Select the type of chart you want to create, and then click OK.<\/span>\r\n\r\n<span style=\"font-weight: 400\">Usually, Google Sheets will create a chart based on the data you selected. However, if you want to create a scatter chart, you will need to specify the chart type in the <\/span><b>Chart Editor<\/b><span style=\"font-weight: 400\">. Then, in the <\/span><b>Chart Editor<\/b><span style=\"font-weight: 400\">, select <\/span><b>Scatter Chart<\/b><span style=\"font-weight: 400\"> and then click OK.<\/span>\r\n\r\n<span style=\"font-weight: 400\">Now that we have created the chart, you can customize it in the <\/span><b>Chart Editor<\/b><span style=\"font-weight: 400\"> as you see fit. You can add labels, titles, and other features. Your data should be displayed in the chart as well.<\/span>\r\n<h3><span class=\"ez-toc-section\" id=\"Find_The_Line_Of_Best_Fit_On_Google_Sheets\"><\/span><b>Find The Line Of Best Fit On Google Sheets<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<span style=\"font-weight: 400\">No equation is needed to add a trendline to a chart in Google Sheets. You can simply customize the chart and then add the line of best fit.<\/span>\r\n\r\n<span style=\"font-weight: 400\">There are <\/span><b>Setup <\/b><span style=\"font-weight: 400\">and <\/span><b>Customize <\/b><span style=\"font-weight: 400\">tabs on the menu. You need to click on the <\/span><b>Customize<\/b><span style=\"font-weight: 400\"> tab, and then under <\/span><b>Customize <\/b><span style=\"font-weight: 400\">tools, you will find the Series option. Here, there are three check boxes that will allow you to add a trendline. Click on the <\/span><b>Trend Line<\/b><span style=\"font-weight: 400\"> check box and you will see the trendlines on the chart.<\/span>\r\n\r\n<span style=\"font-weight: 400\">The trendline is drawn on the chart based on the data you have selected. If it shows an upward or downward trend, the line will be drawn at the peak or trough of the trend, respectively.<\/span>\r\n<h3><span class=\"ez-toc-section\" id=\"Making_Changes_To_The_Trend_Line\"><\/span><b>Making Changes To The Trend Line<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<span style=\"font-weight: 400\">If you want to change the trendline, you can do so by customizing the options under the trendline and then make your changes. You can change the type of line, the color, and the weight.<\/span>\r\n\r\n<span style=\"font-weight: 400\">One can pick <\/span><b>linear<\/b><span style=\"font-weight: 400\">, <\/span><b>exponential<\/b><span style=\"font-weight: 400\">, or a <\/span><b>logarithmic <\/b><span style=\"font-weight: 400\">function. You can also show the <\/span><b>R2 value<\/b><span style=\"font-weight: 400\">, which is a measure of the correlation between the data points and the trendline.<\/span>\r\n\r\n<span style=\"font-weight: 400\">The key is just to experiment with the different options to see what looks best on your data. This is an excellent way to see how the different options impact the overall look and feel of the chart.<\/span>\r\n<h2><span class=\"ez-toc-section\" id=\"Changing_The_Type_Of_The_Trendline\"><\/span><b>Changing The Type Of The Trendline<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<span style=\"font-weight: 400\">You can use<\/span> <a href=\"https:\/\/www.fusioncharts.com\/blog\/what-are-the-types-of-trend-lines\/\" target=\"_blank\" rel=\"noopener\"><i><span style=\"font-weight: 400\">6 different types of trendlines<\/span><\/i><\/a><span style=\"font-weight: 400\"> in Google Sheets. Each has its own usage and benefits. Here we will briefly introduce each type and when to use it.<\/span>\r\n<h3><span class=\"ez-toc-section\" id=\"Linear_Trendline\"><\/span><b>Linear Trendline<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-21135 size-medium\" src=\"https:\/\/www.fusioncharts.com\/blog\/wp-content\/uploads\/2022\/09\/Screenshot-30-300x177.webp\" alt=\"Adding multiple trendlines may include choosing linear or exponential trendlines, and setting the start and end points.\" width=\"300\" height=\"177\" srcset=\"\/blog\/wp-content\/uploads\/2022\/09\/Screenshot-30-300x177.webp 300w, \/blog\/wp-content\/uploads\/2022\/09\/Screenshot-30.webp 690w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>\r\n\r\n<span style=\"font-weight: 400\">This type of trendline is used to show a constant trend. It is usually used when there is an increasing or decreasing trend pattern in the data. The slope of the straight line is constant and indicates how much the data has changed for each unit of time.<\/span>\r\n<h3><span class=\"ez-toc-section\" id=\"Exponential\"><\/span><b>Exponential<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<span style=\"font-weight: 400\">For positive data, an exponential trendline will show an upward slope. For negative data, an exponential trendline will show a downward slope. This trendline is used when there is a significant change in the data over a short period.<\/span>\r\n<h3><span class=\"ez-toc-section\" id=\"Polynomial\"><\/span><b>Polynomial<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<span style=\"font-weight: 400\">Fluctuations in data will be reflected in a polynomial trendline. The trendline will have a slope that changes over time, showing the intensity of the fluctuations.<\/span>\r\n<h3><span class=\"ez-toc-section\" id=\"Logarithmic\"><\/span><b>Logarithmic<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<span style=\"font-weight: 400\">For a quick fall and then a quick rise in data, a logarithmic trendline will be appropriate. The trendline will have a slope that slowly changes over time, indicating a slow change in the data. This trendline is used when there is a change in the data that is not significant enough to warrant a linear or exponential trendline.<\/span>\r\n<h3><span class=\"ez-toc-section\" id=\"Power_Series\"><\/span><b>Power Series<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<span style=\"font-weight: 400\">Sometimes data is increasing at a certain rate. Here, a power series trendline would be appropriate. The trendline will have a slope that is increasing over time.<\/span>\r\n<h3><span class=\"ez-toc-section\" id=\"Moving_Average\"><\/span><b>Moving Average<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-21136 size-medium\" src=\"https:\/\/www.fusioncharts.com\/blog\/wp-content\/uploads\/2022\/09\/Screenshot-35-300x192.webp\" alt=\"When you are adding multiple trendlines, the moving average type of trendline can be the most effective depending on the data.\" width=\"300\" height=\"192\" srcset=\"\/blog\/wp-content\/uploads\/2022\/09\/Screenshot-35-300x192.webp 300w, \/blog\/wp-content\/uploads\/2022\/09\/Screenshot-35.webp 421w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>\r\n\r\n<span style=\"font-weight: 400\">If your data has extreme values that move around a lot, a moving average trendline may be a better option. The trendline will smooth out fluctuations in the data.<\/span>\r\n<h2><span class=\"ez-toc-section\" id=\"Adding_Multiple_Trendlines_In_Google_Sheets\"><\/span><b>Adding Multiple Trendlines In Google Sheets<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<span style=\"font-weight: 400\">Suppose you have more than one series of data in your chart. You can add multiple trendlines to the chart to show the different trends. You can add a trendline to each series of data by going to the <\/span><b>Chart Editor<\/b><span style=\"font-weight: 400\">, <\/span><b>Customize<\/b><span style=\"font-weight: 400\">, then <\/span><b>Series<\/b><span style=\"font-weight: 400\">. On the drop-down menu, make sure the series you want to add a trendline to is selected. To add a trendline, check the box next to the trendline type you want to use.<\/span>\r\n<h2><span class=\"ez-toc-section\" id=\"Using_The_TREND_Function_To_Make_A_Trendline\"><\/span><b>Using The TREND Function To Make A Trendline<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<span style=\"font-weight: 400\">This function calculates a trendline based on the data. You can forecast future market movements by using this function to create a trendline.<\/span>\r\n\r\n<span style=\"font-weight: 400\">Under the following syntax, the <\/span><b>TREND <\/b><span style=\"font-weight: 400\">function operates on a data series and returns a trendline.<\/span>\r\n\r\n<b>=TREND(known_data_y, [known_data_x], [new_data_x])<\/b>\r\n<h2><span class=\"ez-toc-section\" id=\"Visualize_The_Trend\"><\/span><b>Visualize The Trend<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<span style=\"font-weight: 400\">Trendlines help visualize the trend of data. When plotted on a graph, a line of best fit shows the trend of the data. The trendline can make predictions about future data points.<\/span>\r\n\r\n<span style=\"font-weight: 400\">Analysts and investors often use trendlines to help make predictions about future events. They compare values over time to see if there is a trend, and then make predictions about what will happen next.<\/span>\r\n\r\n<a href=\"https:\/\/www.fusioncharts.com\/blog\/modern-data-visualization-trends\/\" target=\"_blank\" rel=\"noopener\"><i><span style=\"font-weight: 400\">Visualization<\/span><\/i><\/a><span style=\"font-weight: 400\"> is key when using trendlines in Google Sheets.
