Scatter with Smooth Lines: An Overview
A scatter plot with smooth lines is a data visualization tool that combines the raw data points of a scatter plot with a smooth line. This smooth line is drawn through the data points to represent the overall trend, helping minimize the effects of random fluctuations or noise. By identifying the general patterns or trends, such plots provide clearer insights into the data.
Creating Scatter Plots with Smooth Lines in Python
To create a scatter plot with smooth lines in Python, you can use the SciPy library. Specifically, the scipy.interpolate.make_interp_spline() function computes the coefficients of an interpolating B-spline, allowing a smooth line to be added to the scatter plot. The np.linspace() function from NumPy generates evenly spaced numbers over a specified interval, ensuring a smooth curve. The combined use of these functions yields a smooth, visually appealing trend line.
Benefits of Using Scatter with Smooth Lines
Scatter plots with smooth lines are invaluable for observing relationships between two numeric variables. They report individual data point values and overall data patterns, making it easier to identify correlations, unexpected data gaps, and outliers. These plots are commonly used in various fields to visualize data trends and make informed decisions.
Example in Excel
In Excel, smoothed lines in scatter plots are calculated using a cubic spline algorithm. This ensures that the plotted smooth lines accurately reflect the overall trend of the data, providing a clear and precise visual representation.
When to Use a Scatter with Smooth Lines
Overview of Scatter with Smooth Lines
A Scatter with Smooth Lines chart is ideal for visualizing the relationship between two variables. It represents data points on a Cartesian plane and connects them with smooth curves to illustrate trends.
Benefits of Scatter with Smooth Lines
This type of chart is excellent for identifying non-linear relationships and trends within datasets. The smooth lines provide a clear visual summary, making it easier to spot trends at a glance.
Comparison with Other Charts
Compared to a standard scatter plot, Scatter with Smooth Lines can make complex datasets more comprehensible by reducing visual clutter. Unlike bar charts, which are better for categorical data, Scatter with Smooth Lines is preferable for continuous data.
Drawbacks of Scatter with Smooth Lines
Despite its strengths, this chart type may obscure individual data points, making it less effective for analyzing outliers. It may also give a false impression of continuity in discrete datasets.
When to Use Another Chart Type
For purely categorical data, consider using bar or pie charts for clearer insights. Use line charts for simpler time-series data without the need for smooth trend visualization.

How to Generate a Scatter Plot with Smooth Lines in Excel or Google Sheets
Creating Scatter Plot with Smooth Lines in Excel
To create a scatter plot with smooth lines in Excel, start by clicking on the chart. Navigate to the Chart Design tab on the ribbon, then click Add Chart Element. Select Trendline and then More Trendline Options. Choose the Moving Average option and set the Period to a value that suits your dataset. This method smooths out the plot to form a curve.
Smooth Line Scatter Plot in Google Sheets
In Google Sheets, you can simulate a scatter plot with smooth lines using a line chart. First, create your dataset. Highlight your data, then click Insert followed by Chart. In the Chart Editor, change the Chart type to Line chart. Go to the Customize tab in the Chart editor and adjust the Point size to 10px. This adds points to your line chart, giving the impression of a scatter plot with smooth lines.
Using Trendline for Curve Fitting in Google Sheets
For more precise curve fitting in Google Sheets, use the Trendline function. Create a line chart and add a trendline by choosing Polynomial for the Type of trendline in the Chart editor. Adjust the Polynomial degree as needed to get a curve that best fits your data without overfitting.
