3. Dynamic charts – Definition
All charts change dynamically when the underlying data changes
Challenge: change what the chart is showing without using chart dialogs
User controls on the sheet to set chart parameters

4. What makes a chart dynamic?
Data source is the key
User can interact with cell values via controls
type values manually
select from drop-down
use slider controls (will not work in browser)
Cell values feed into formulas that assemble the chart data source

5. What can be made dynamic
Rolling data, e.g. last 6 months
Timeline start and duration
Conditional formatting of data points (high/low)
Highlighting key data in busy charts

6. Filter data source
Excel Table object – filter with slicers on dashboard
Slicers for Table objects were introduced in Excel 2013
Pivot table slicers

7. Named ranges Find the data using formulas
Based on parameters provided via dashboard controls
Chart labels can be the anchor element
Offset from label name to define series range
Naming tips (don’t start with ‘c’ or ‘r’)
Techniques for applying range names as chart data source

8. Fixed data range with formulas
Chart source range is fixed
Formulas pull the data into that grid
Combine with GetPivotData() to pull data from Pivot Table for a powerful combination of slicers, named ranges and formulas.

9. Controlling chart elements
Consistent maximum Y axis value
Conditional highlighting
Series highlighting
Axis labels (time line in XY charts)
Data labels

10. Dynamic labels Text in cells instead of built-in labels
Before Excel 2013:
The manual way
XY Chart Labeller add-in
Excel 2013 and up
Value from cells
XY Chart Labeller add-in (because it’s backwards compatible)

11. Limitations Some aspects cannot be automated without VBA
Adjusting plot size
Setting min and max axis values (vote for this!)
VBA and forms controls (sliders) don’t work in Excel Online or Excel for mobile.
Slicers don’t work in Excel for mobile
