Ad Hoc View – Percent Column Chart
Percent Column charts display multiple measures of a group as portions of a single column of fixed size.
Depending on the data you are investigating, it may be useful to look at percentages rather than total amounts. e.g. What percentage of income is related to wages or pensions for an area.
Charts allow you to graphically display your data. There are a number of different chart types available, but two of the most familiar are generally Column and Bar charts.
Step 1. Open or create a new ad hoc view (refer to the Creating Ad Hoc Views article for further information)
Step 2. Select Chart from the drop-down at the top of the screen.
By default, column chart is selected.
Step 3. To change the chart type, click the options drop down in the top left corner of the chart area.
Step 4. Select Chart Types
Hover your mouse over the chart thumbnail to see the chart type name.
There are three column charts available:
Each chart type displays your data in slightly different ways.
Select Percent Column Chart.
Step 5. Click and drag a measure from the measures area on the left-hand side pane to a row or column.
e.g. Income Amount
Tip: All charts must have at least one measure.
With a single measure and no fields, the chart displays the total for the measure.
Step 6. Click and Drag a field to the rows area
e.g. Primary Address City.
This allows the measure data to be broken up by the field information.
You’ll notice when the field is added that the chart may not change.
In the right-hand side pane there is a section caller Data Level.
The slider allows you to quickly change the level at which the data is reported. When the slider is all the way to the left, it shows the measure total.
Step 7. Slide the slider all the way to the right.
Tip: If you hover your mouse over the left and right ends of the slider the data level options will be displayed. Sometimes there are multiple options along the length of the slider.
The measure is now broken up by the added field. Each measure is displaying 100% in each column.
Step 7. To break the measure in a more meaningful way, add a field to the columns section.
Again, the chart does not change as the slider begins at the totals (far left) end.
Step 8. Slide the columns slider to the right.
Note – to make the chart clearer, we have added a filter to only show a subset of data. For more information on Filters, refer to Ad Hoc View – Filters article
The measures are now split by the additional column field (Gender) but grouped by the row field (Primary address city).
If you add additional fields to the rows or columns, the sliders will update and the measures will be split if you move the sliders.
You may find that the chart becomes less useful if you add too many fields.
