Sparklines are small (word-size) charts that illustrate trends and variations.
And they are now ease to create from OpenOffice.org Calc using EuroOffice Sparkline!
Sparklines are simple things and now creating them is simple too. Just select the data series you want to use as the basis of the sparkline and click EuroOffice Sparkline in the Insert menu. Additional details of the sparkline can be customized in the EuroOffice Sparkline dialog. Sparklines can be augmented with small dots that mark the start and end of the line and high or low points of the line.
These dots are conventionally colored red for the start and end and blue for the maximum and minimum values.
These colors help you associate numerical information with the data points as in the example to the right.
Sparklines can be used to great effect in charts, but also in text. An example of this can be found in the EuroOffice Sparkline manual.
For more details on sparklines we can recommend Edward Tufte's treatise.
