3D SCATTER PLOT MINITAB

With Groups Create a 3D scatterplot that displays predictor variables on the x-axis and y-axis and the response variable on the z-axis, divided into groups. Change the box appearance On the Attributes tab, you can edit the fill type, fill color, line type, line color, and line size. You can change the brightness of the surface, and the number and position of up to three surface lights. Data points that tend to rise together suggest a positive correlation. The surface of the 3D surface plot is illuminated in areas so that you can better see surface features. For information on adding or changing the grouping variables for an existing graph, go to Display groups on graphs. Adjust the relative positions of the surface lights The x-, y-, and z- coordinates for the positions of lights on a 3D surface plot are expressed relative to the center of the data region, which is coordinate 0 0 0.

Use a 3D surface plot or a 3D wireframe plot to examine the relationship between a response variable Z and two predictor variables X and Y , by viewing a three-dimensional surface of the predicted response. Note For more information on editing these graph features, including how to change a surface plot to a wireframe plot, go to the following topics. Viewing 3D surface plots and 3D wireframe plots Learn more about Minitab The coordinates for these positions are: Use the following buttons on the 3D Graph Tools toolbar to rotate the graph. A food scientist wants to determine the optimal time and temperature for heating a frozen dinner. Click and hold a button for continuous rotation.

Click a button once to rotate the graph in small increments. For more information on editing these graph features, including how to change a surface plot to a wireframe plot, go to the following topics.

Interpret the key results for 3D Scatterplot – Minitab

Outliers fall far from the main group of data points. Rotate the graph clockwise or counterclockwise about the x-axis. Rotate the lights clockwise or counterclockwise about the y-axis. Coordinate units are designed to be consistent between x, y, and z, and are thus not related to the data units.

Click and hold a button for continuous rotation. For example, you may want scatter examine how temperature and humidity affect the drying time of paint, or how horsepower and tire pllot affect a vehicle’s fuel efficiency.

Use the following buttons on the 3D Graph Tools toolbar to pllot the lights. The following images show elements that you can display on a 3D plot. Notice that the red light illuminates more of the nearer face of the graph than in the previous example.

A 3D scatterplot contains the following elements: Note For more information on editing these graph features, including how to change a surface plot to a wireframe plot, go to the following topics.

Rotate the graph clockwise or counterclockwise about the x-axis. When you create a 3D scatterplot, you usually display predictor variables on the x-axis and scxtter y-axis and the response variable on the z-axis.

Create a 3D scatterplot that displays predictor minktab on the x-axis and y-axis and the response variable on the z-axis. The coordinates for these positions are: By using this site you agree to the use of cookies for analytics and personalized content.

In this example, y for Light 1 is set to zero, so it is centered directly above the graph. For more information, go to Create a 3D scatterplot with groups. Proportional to data ranges.

However, heating at the longest intervals combined with the highest temperatures also results in low scores because minitwb food becomes over-cooked.

Viewing 3D surface plots and 3D wireframe plots

The surface of the 3D minitag plot is illuminated in areas so that you can better see surface features. Rotate the graph clockwise or counterclockwise about the y-axis. Data points that tend to rise as other data points minitag to decline suggests a negative correlation. Response values on the z-axis. Return the lights to their original positions. You can change the mimitab of the surface, and the number and position of up to three surface lights.

For example, on the following 3D scatterplot, the 3D box is colored light yellow. For example, the following scatterplot shows the relationship between quality, time, and temperature for each operator. The coordinates for the default positions are: When you click a button, a preview window pops up to show exactly how the graph will spin.

This allows you to more thoroughly explore the relationships among the variables. Toolbar item Action Rotate the graph clockwise or counterclockwise about the x-axis.

Viewing a 3D scatterplot

You can choose to represent the predicted scatter as a smooth surface or a wireframe. This allows you to more thoroughly explore the relationships among the variables. Use a 3D scatterplot to see how a response variable relates to two predictor variables.

Adding project lines helps you visualize each point’s position in three-dimensional space.
