Getting Started with Equation Plotting

Creating a Scatter Plot:

To plot an equation in Google Sheets, begin by entering the values or formulas for the independent and dependent variables into separate columns. Select the data range and navigate to the “Insert” menu. Choose “Chart” and opt for the “Scatter Chart” type. This creates a basic scatter plot with the independent variable on the x-axis and the dependent variable on the y-axis.

Adding a Trendline:

To visualize the equation that best fits the data points, click on the scatter plot and select the “Chart Editor” icon. Under the “Customize” tab, enable the “Trendline” option. Choose the desired type of trendline, such as linear, exponential, or polynomial, to represent the equation.

Equation Display:

The trendline’s equation and statistics are displayed on the chart. This provides a concise representation of the mathematical relationship between the variables, allowing for quick analysis and interpretation.

Customizing Axis Labels and Gridlines

To enhance the readability and clarity of your plot, customize the axis labels and gridlines. Right-click on the axis and select “Axis Options.” Adjust the label text, font size, and color to suit your preferences. Similarly, modify the gridlines by clicking on the chart background and selecting “Gridlines.” Choose the line style, color, and spacing to improve the visual representation.

Advanced Plotting Techniques

For more complex data sets and sophisticated visualizations, explore advanced plotting techniques:

Multiple Trendlines

Plot multiple trendlines simultaneously to compare different equations or models. Select the data range for each trendline and add them to the chart separately.

Custom Polynomial Equations

Fit a polynomial curve of a specific degree to the data by using the “Custom Equation” option in the trendline settings. Input the polynomial equation in the provided field.

Adding Secondary Axes

Use secondary axes to plot data with different units or scales. Right-click on the chart and select “Axes.” Enable the “Secondary” axis and link it to the appropriate data range.

Creating a Scatter Plot with Equation

To create a scatter plot with an equation in Google Sheets, follow these steps:

Enter your data into two adjacent columns in Google Sheets.
Select the data by clicking and dragging over it.
Click the “Insert” menu, hover over “Chart,” and select “Scatter chart.”
In the chart editor, click the “Customize” tab.
In the “Series” section, click the “Add trendline” button.
Select the type of trendline you want to add, such as “Linear,” “Polynomial,” or “Exponential.”
In the “Trendline options” section, you can customize the appearance and display of the trendline.
To display the equation for the trendline, click the “Show equation on chart” checkbox.

Here’s a more detailed explanation of step 6:

Select the Trendline Type

Trendline Type	Equation Form
Linear	y = mx + b
Polynomial	y = a_nxⁿ + a_n-1x^n-1 + … + a₁x + a₀
Exponential	y = a * b^x
Power	y = a * x^b

Choose the trendline type that best fits your data. The equation for the trendline will be displayed in the chart with the corresponding coefficients. You can use this equation to make predictions or analyze the relationship between the two variables in your data.

Adding a Trendline to Data

A trendline is a line that displays the trend of the data in a scatter plot. It can help you see the relationship between the two variables in the data.

Select the scatter plot you want to add a trendline to.
Click on the “Insert” menu and select “Trendline”.
In the “Trendline” dialog box, select the type of trendline you want to add.
Click on the “Options” tab to set the options for the trendline.
Click on the “OK” button to add the trendline to the scatter plot.

There are several different types of trendlines that you can add to a scatter plot. The most common type of trendline is a linear trendline. A linear trendline is a straight line that shows the average relationship between the two variables in the data.

Other types of trendlines include:

Exponential trendline: A exponential trendline is a curved line that shows the relationship between two variables that are growing or decaying at a constant rate.
Logarithmic trendline: A logarithmic trendline is a curved line that shows the relationship between two variables that are growing or decaying at a variable rate.
Polynomial trendline: A polynomial trendline is a curved line that shows the relationship between two variables that are growing or decaying at a variable rate.

You can also add a trendline to a scatter plot that has multiple data series. To do this, select the scatter plot and then click on the "Insert" menu. Select "Trendline" and select the "Custom" tab. In the "Custom" dialog box, select the type of trendline you want to add and then select the data series that you want to include in the trendline.

Fitting a Polynomial Curve to Data

Polynomial regression is a method of finding the best-fit polynomial curve for a set of data points. A polynomial is a mathematical expression that consists of a sum of terms, each of which is a constant multiplied by a different power of a variable. The degree of a polynomial is the highest power of the variable that appears in the polynomial.

To fit a polynomial curve to a set of data points, you can use the POLYFIT function in Google Sheets. The POLYFIT function takes two arguments: an array of x-values and an array of y-values. It returns an array of coefficients for the polynomial that best fits the data points.

Once you have the coefficients for the polynomial, you can use them to plot the polynomial curve. To do this, you can use the following steps:

1. Create a new column in your spreadsheet to store the predicted y-values.
2. In the first cell of the new column, enter the following formula:

=POLYNOMIAL(A2, $B$2:$B$6)

where A2 is the x-value for the first data point, and B2:B6 is the range of y-values for the data points.
3. Copy the formula down the column to fill in the predicted y-values for the remaining data points.
4. Select the range of cells that contains the x-values and the predicted y-values.
5. Click the Insert chart button and select the Scatter chart type.
