Before you can create dynamic charts, you first need to learn how to define the name of the table area, and ease of reference behind. The method is: Formula - defined name: define the name, fill in the name and reference position, reference position can use the formula.
2. Form Controls
Tool to achieve dynamic charts may first form control is used to open the file - Option: Customize Ribbon - Right: the main tab - check development tools, development tools added to Excel tab.
Dynamic chart form controls may be used are two: check boxes and scroll bars, choice of development tools - control: Insert: box / scroll bars.
Check boxes are use: defined name: = IF (cells check box to be linked to the selected data area, the data area of the blank), is inserted into a box, then right: Format Control - Control: Value: selected: cell link, cell link to select an empty cell.
Scrollbar usage is: inserting a scroll bar, and then right: Format Control - Control: minimum & maximum cell link selection to an empty cell.
3. OFFSET function and the function COUNTA
Usage OFFSET function is: = OFFSET (reference grid, offset to the left lines, columns shifted downward region a few lines, columns region), is to select the table region; Usage COUNTA function is: = the COUNTA (table area), is to calculate the number of non-empty cells in the table area.
OFFSET function built COUNTA function can dynamically select the table areas, such as: = OFFSET (reference grid, COUNTA (column where the reference grid) -10,0,10,1), where the action is always a reference grid to select the last column 10 data.
