![]() So that the selected numeric values will be displayed in markers, as shown in the result below. Step 4 – Select the first option, which shows Scatter with only Markers. Step 3 – Click on the down arrow so that we will get the scatter chart list shown below. Step 2 – Go to the Insert menu and select the Scatter Chart. Step 1 – First, select the X and Y columns as shown below. To apply the scatter chart using the above figure, follow the steps below. ![]() In this example, we will see how to apply to an Excel scatter chart with only Markers using the example below.Ĭonsider the table below, which has random X and Y values. It can now be used to make certain predictions.įor example, suppose the 1 mole sample of helium gas is cooled until its volume is measured to be 10.5 L.You can download this Scatter Chart Excel Template here – Scatter Chart Excel Template Example #1 – Using Scatter Chart with only Markers The graph contains a visual representation of the relationship (the plot) and a mathematical expression of the relationship (the equation). By graphing the five measured values, a relationship is established between gas volume and temperature.whether the fit of the line to the data is good or bad, and why.the equation of the best-fit trendline to your data.Then record the following information on your report: Print out a full-sized copy of your prepared graph and attach it to your report.You must judge the quality of the fit and the suitability of this type of fit to your data set. Note that the program will always fit a trendline to the data no matter how good or awful the data is. Generally, R 2 values of 0.95 or higher are considered good fits. The closer the R 2 value is to 1, the better the fit. The R 2 value gives a measure of how well the data is fit by the equation. The equation that now appears on your graph is the equation of the fitted trendline.Now select the Display Equation on Chart box and the Display R-squared value on Chart box. Notice that the Linear button is already selected.This will display the option shown in Figure 7. Click the Chart Elements button next to the upper-right corner of the chart.When you do this, all the data points will appear highlighted. Do this by clicking on any one of the data points. To do this you first need to "activate" the graph. A trendline represents the best possible linear fit to your data. Your next step is to add a trendline to the plotted data points.To change the titles, click the text box for each title, highlight the text and type in your new title (Figure 6).Note that it is important to label axes with both the measurement and the units used. Click on Axis Titles (select Primary Horizontal Axis Title and Primary Vertical Axis Title) to add labels to the x- and y-axes.The graph should be given a meaningful, explanatory title that starts out “Y versus X followed by a description of your system.Switch to the Design tab, and click Add Chart Element > Chart Title > Above Chart. ![]()
