Parts of a graph

Here is a column graph created in Sybase WorkSpace that contains most major parts of a graph. It shows quarterly sales of three products: Stellar, Cosmic, and Galactic printers:

The sample illustrates a graph with all its parts labeled. The title is Printer Sales, the y axis is labeled Value axis and displays values of 0 to 70. The Value axis label is Sales ( units ). The x axis is labeled Category axis and is marked off by the axis text Q1, Q2, Q3, and Q4. The word Quarter is the Category axis label. The area  labeled Legend at the bottom shows three series labeled Stellar, Cosmic, and Galactic, with color keys for each. The graph has columns for each quarter that represent sales in units for the three series.
