Scatter
Scatter charts, also known as scatter plots or scatter graphs, observe relationships between variables and are frequently used to display continuous data comparison.
The demo below compares the consumer price index vs. wage increases in Norway over the last four decades. The x-axis indicates values for the consumer price index, whereas on the y-axis indicates the wage increases.
To avoid data cluttering, the data set from 1991 to 2010 are deactivated by default. Users can easily activate or deactivate any data set by clicking on the correspondent legend.
