Using bar charts and histograms to look at the distribution of data in your chart and
drill down into the contents to concentrate on information that is of interest.
To open a bar chart or histogram:
-
Click the Analyze tab, and then in the Gain
Insight group, click Bar Charts and Histograms.
The Bar Charts and Histograms pane opens.
-
Click the New tab.
Analyst's Notebook inspects the content of your chart and lists a useful
set of bar charts and histograms that apply to your data. Any entry that would produce a bar chart
or histogram with just one category or an even spread with just one entry in each category is not
displayed in the list.
Each list entry includes up to three components.
Component |
Description |
Label
|
A description of the bar chart or histogram. For example:
- Link Type - lists the available types of link on your chart.
- Label Value - lists the values of chart item labels.
|
Count Summary |
A count of the total number of items on the current chart that match the criteria. This
count is split into ends (or entities) and links. |
(as histogram) |
Any list entry with this component can be opened as a histogram or a bar chart. |
Note: To list all possible bar charts and histograms, select the Show All
check box.
-
Enter the name of a property or attribute in the Search
properties field.
The list updates as you type to show the available bar charts and histograms that match
your search text.
-
Click the label to open a bar chart or if (as Histogram) is appended to
the label, you can click (as Histogram) to open a histogram.
You can open as many bar charts and histograms as you want. To open a bar chart but remain on the
New page of the Bar Charts and Histograms pane, for
example to add further bar charts or histograms, right-click an entry and select Add Bar
Chart.
Note: If a bar chart is open for the histogram that you select, you cannot open it as a histogram
without first closing the bar chart. In the same way, you cannot open a bar chart without first
closing a corresponding histogram. Analyst's Notebook prompts you to change
it from one to the other.
Each bar chart that you open appears on the Bar Charts page of the
Bar Charts and Histograms pane. By default, if the value for a row in a bar
chart is zero, the row is not displayed. To display rows that have a zero value, on the
Options page of the Bar Charts and Histograms pane, select
the Include Empty Rows check box under Bar Chart Rows.
Any histograms that you open appear in a separate Histograms
window.
You can now focus on specific chart items or apply filters to investigate your data
further. You can also look at combinations of properties by viewing heat matrices for the histograms
that are open.
