A Scatter Chart is a good tool for tracking trends and understanding process shifts over time. It can be used to spot a possible correlation between two variables that relate to the same event.
You can use a simple technique called "data brushing" to select any number of consecutive data points on a chart. Then, select from options that allow you to focus on just that data or to exclude it from the retrieval.
You can click any data point or limit line to display its value.
Depending on how your GainSeeker is configured, certain access rights may be required to use this function.
