5.1.3 2D Binning

Summary

The 2D Frequency Count/Binning operation counts the frequencies for data with two variables.A 3D bar graph and/or an image plot of the results can be generated, giving a graphic representation of data distribution.

What you will learn

  • How to count the frequencies for data with two variables.
  • How to plot 2D binning into 3D Histogram.

Steps

This tutorial is associated with <Origin EXE Folder>\Samples\Tutorial Data.opj.

  1. Open the Tutorial Data.opj and browse to the folder 2D Frequency Count (Binning), and activate the 3D Histogram.dat book.
  2. Highlight column A and column B, select menu Statistics: Descriptive Statistics: 2D Frequency Counts/Binning to bring up the TwoDBinning dialog.
  3. Specify the following settings in the dialog box:
    • Uncheck the Auto checkbox, set the Bin Size for X to 40.
    • Set the Bin Size for Y to 15.

      Click OK to close the Fill tab, and click OK in Plot Details to close the dialog.

    3. Double click the Axis to open the Axis dialog and go to Scale tab, specifies the Scale for XYZ axis follows the graphs below:
      • Change the scale for X axis in X icon form 820 to 1220 with Major Ticks value 40.

      • Change the scale for Y axis in Y icon form 127.5 to 277.5 with Major Ticks value 15.
      • Change the scale for Z axis in Z icon form 0 to 100 with Major Ticks value 20.
    4. Change title for X, Y, Z axis in Title tab into Tensile Strength, Brinell Hardness and Number of Tests, respectively. Click OK to apply the setting and close the dialog.
