absolute cell reference
refers to the address of a cell, when both the column and row needs to remain constant regardless of the position of the cell when the formula is copied to other cells. Cell reference that does not adjust to the new cell location when copied or moved. $D$2 or $A$1*B4
mixed cell reference
refers to referencing a cell within the formula where part of the cell address is preceded by a dollar sign to lock – either the column letter or the row value – as absolute and leaving the other part of the cell as relatively referenced. When you add one dollar sign, but not the other, you have a mixed – $B10 or B$10.
pie chart
type of chart; commonly used for depicting parts of the whole such as comparing staff performance within a department or comparing the number of transactions of each product category within a period of time.
line chart
type of chart; help convey change over a period of time. These are great for exploring how data in a business, such as sales or production, changes over time.

type of chart; a variation of a stacked line chart that emphasizes the magnitude of change over time and visually depicts a trend. This type of chart has a nice visual characteristic because each colored layer changes, growing or shrinking, as it moves across time periods.
sparklines
small charts that are embedded into spreadsheet, usually beside the data to facilitate quick analysis of trends. Can be used within a spreadsheet to give an immediate visual trend analysis, and it adjusts as the source data changes. This type of chart can graphically depict the data over time through either a line chart or a bar chart that accumulates the data.
