In many cases, you can narrow the focus of a chart by selecting a subset of the data points on the chart itself to focus on those data points.
To focus a chart by selecting data points, complete the following steps:
-
Click at a spot that is above the highest vertical axis value you want and left of the first horizontal axis value, and hold down the left mouse button.
-
Drag the mouse pointer until the green selection area includes all of the data points you are interested in. This action is sometimes referred to as "lassoing" the data points.
You can also click a single line or bar in the chart to focus the chart solely on the data that line or bar represents. wInsight Analytics displays only that line or bar. This is particularly useful if a line chart has so many lines that you cannot see the data clearly.
-
Release the mouse button.
wInsight Analytics redisplays the chart based on the selected data. The horizontal and vertical scales are changed automatically to provide the most useful display of the selected chart line.
Focusing a chart in this way actually changes the corresponding filter values. For example, if you select data for related to a subset of the periods along the horizontal axis, that applies a period filter. As a result, focusing a chart changes not only that chart but all other analytic objects on the tab that are subject to that filter.
