Performing visual analysis

After you access the Visual Analysis interface in your browser by any of the ways introduced in Starting Visual Analysis session, you can make use of the tool to analyze the data in a business view intuitively and conveniently.

The following are operations you can make use of in order to interact with data. Note that only group and aggregation fields can be added into the data presentation area.

Adding data fields as column or row headers

Group and aggregation fields can be added as column or row headers. Drag a data field from the Resources panel and drop it to the proper control box, following the instructions of the four control boxes highlighted in the below image. The button beside the four control boxes allows you to select a group or an aggregation field from the drop-down list instead of dragging the object from the resource panel.

When an aggregation is added as a header, the aggregation will be used to draw axes in the header cells.

Multiple fields can be added as column or row headers. For column headers, the order of the group fields or the aggregation fields from left to right decides the grouping order from the first level to the last level. That is, the grouping order is from left to right. For example, there are Year, Region, and Category group fields added as the column headers and are displayed from left to right. Year will be the first level group, Region the second, and Category the last. For row headers, the grouping order is from bottom to top.

When you drag a field to be a header, you can decide its position if there are already existing fields, or if you are not satisfied with the current grouping order, you can adjust the fields' order by dragging and dropping.

To remove a data field from being a column or row header, drag the field outside of its control box.

Changing the display type of the data values

To specify the way of presenting the data values, click the Display Type button which may vary with the context and select the required display type from the drop-down list.

Showing the tip information of the data values

Put the mouse pointer on any date value in the date presentation area, and a tip box will be displayed showing the detailed information of the value.

Showing the labels of the members of a data field

For example, to show the country names in the data values displayed in the data presentation area, drag the Country field to the button in the legend section. See Label legend for more.

Dividing pie into sections by an aggregation field

When the display type is Pie, you can make the pie divided around the center according to an aggregation field. For example, to divide the pie by total sales, drag the Total Sales field to the Slice button in the legend section. See Slice legend for more.

Within a display type, after a field is bound with a legend type, you can directly drag the field to another legend type, or use the context menu after you click the field name bar under the original legend.

Showing/Hiding the row/column title/header

To show or hide the row/column title or header, click a related row/header control box and then select or unselect Show Title or Show Header on the drop-down menu.
