Configuring Histogram Chart Options
For histogram charts, you can specify how the data should be grouped into bins
for frequency count. You can also specify other options such as whether the
bins should be displayed from the highest to the lowest distribution as a Pareto
chart, or whether cumulative percentage should be added. These configuration
options are available in the Chart Types and Configuration
dialog under the Histogram Options tab.
Bin Settings
You can create bins with your specified bin ranges by choosing the Custom
button, or you can have the bin ranges automatically calculated for you by choosing
the Basic button. By default, six bins are automatically calculated
based on all the data values.
Have the Bin Ranges Automatically Calculated For You
Bin ranges can be automatically calculated for you if you specify the number
of bins you want or a specified bin size:
- Select Basic under Bin Settings.
- For bin ranges calculated based on number of bins:
- Click the Use Bin Count button.
- Choose or enter the number of bins you want to have in the chart.
As you change the number, the Current Bins pane on the
right automatically shows the recalculated bin ranges and the frequency
count.
- For bin ranges calculated based on a fixed bin size:
- Click the Use Bin Size button.
- Specify the bin size
- Optionally, set the minimum and maximum bin values. To set the values:

- Click Apply to apply the changes, or OK
to apply the changes and exit the dialog.

To create your custom ranges:
- Select the Custom button under Bin Settings.
- To insert a new bin:

box.

The bin ranges automatically adjust based on the addition.

- Click the check box for bin you want to remove from the Current
Bins pane on the right.
- Click Remove Checked Bins.
The bin ranges automatically adjust based on the deletion.

Bin ranges are exclusive for the low value
and inclusive for the high value. That is, a bin with a range of 5000
to 10000 includes values that are greater than 5000 and less or equal
to 10000. |
