9.6.2 The (Plot Details) Data Tab
The Data tab is available when:
- The source plot is a box chart displaying the binned data. (In the Box tab, select Data, Box + Data Overlap, Box(Right) + Data(Left),Box(Left) + Data(Right), Bar + Data Overlap, Bar(Right) + Data(Left), Bar(Left) + Data(Right)under the Type drop-down List.)
- The source plot is a histogram or a column scatter plot.
Data tab for Box Chart or Column Scatter
This group of settings is only available when the source plot is a box chart displaying the binned data or a column scatter plot.
Select Dots, Bin Bars, or Dots + Bin Bars from the Type drop-down list. The Dots option shows the individual binned data points; Bin Bars shows the data in histogram-like style, with bars as the specified bin size.
Select the Single Block Barplot check box to remove the lines between bins when Bin Bars or Dots + Bin Bars is selected from the Type drop-down list.
(Bins are shown here left-aligned.)
Select the Snap Points to Bin check box to align the binned data points horizontally in the bins. Note that if Jitter Points has been selected, this option will be disabled.
When the Type is not Bin Bars (i.e. you have dots to represent data), select the Jitter Points check box to add random noise in X direction to scatter out the data point series. This produces the random jitter, while in the Bins Alignment group, you could produce and customize the regular jitter.
The random offset in X direction is determined according to a normal distribution.
Edit the bin limits by clearing the Automatic Binning check box and editing the associated text boxes, Bin Size, Number of Bins, Beginning, and End.
Number of Bins = (Beginnning-End) / Bin Size
The radio box under the Automatic Binning check box is used to specify how to divide the bins. When you select By Increment, you can enter a fixed size for bins in the Bin Size text box. When you select By Intervals, the Number of Bins text box will be editable.
Bin Height (0-100)
Set the height of each bin. This text box is only available when the source plot is a box chart displaying the binned data. Since the bins are displayed on their sides, this value corresponds to the width of the data point display.
Overlay a distribution curve on the binned data or histogram by selecting Normal, Lognormal, Weibull, Exponential, Gamma, Laplace, Lorentz, Kernel Smooth, Poisson or Binomial from the Type drop-down list. The Preview window displays your selection.
Curves selected from the Type drop-down list are not "fitted" to your data. Instead, Origin determines the data mean, then overlays the curve so that means coincide. If it is a two parameter curve, Origin takes into account the standard deviation of your data.
| Scale to Maximum(%)
Check the Scale to Maximum(%) check box to control the amplitude of the distribution curve. For example, if you set 200, the amplitude of the curve would be doubled compared to the Maximum value of histogram. The distribution curve is normalized when the option is selected.
Note: In addition to selecting values from the drop-down list, you can also manually enter a value in the box.
This group of settings is only available when the source plot is a box chart displaying the binned data.
Data Width (%)
Selected or typed a factor to control the data width in the combo box. This is a percent and only values from 0 to 100 are acceptable.
- <auto> means following Box Width in the Box tab.
- 0 means data points align in a line.
- This control group can be also used for regular jitter (i.e. evenly distribute points in X direction) when Jitter Points is unchecked. To adjust the data width for random jitter, you have to make sure the Jitter Points box is checked in the Type group.
Select Add Distribution Curves to add the distribution curves data to the bin worksheet. When you click the Go button, a Bin workbook containing the computed quantities of bins will be created, and the Plot Details dialog will be closed.
