Graph

A representation of numbers signifying different data sets. Graphs are vitally important in tracking past performance of economic data with the aim of predicting its future behavior. For example, a government agency may create a graph of unemployment claims over time. If claims have trended downward, the agency may predict that unemployment may remain low. Graphs are also crucial for technical analysts, who use them to track securities' performance to help make investment decisions. Graphs are also known as charts.

Charts are used to observe the historical values of variables and, frequently, to spot trends that may provide insights for use in projecting future values. Also called graph. See also bar chart, candlestick chart, line chart, point-and-figure chart.

Standard control charts are effective in analyzing continuous processes such as extrusion, or those that produce a single part at a time, such as injection molding with a single cavity.
On the other hand, X-bar and R charts could be kept for each individual cavity.
In other words, the X chart measures the batch-to-batch variation, while the R chart measures the variation within each batch.
These depend on the number of samples you take for each point on the chart (more detail will be foundin books and manuals on SPC), but for three samples per point, a good approximation is:
Chart 12: POST-PAID % OF TOTAL SUBSCRIBERS BY OPERATOR
Chart 13: PREPAID/WHOLESALE % OF TOTAL SUBSCRIBERS BY OPERATOR
Also known as a time and activity chart, the Gantt chart displays a timeline for each task and is an effective way to keep a project on schedule.
Excel doesn't offer a Gantt as a chart option, but you can produce one anyway--as we have in exhibit 2, below--by using a stacked bar chart.
The solid average line in the R chart is positioned at [R bar], the average of the sample range values.
