Time Combination Graph
The Time Combination Graph combines a series of time series visualizations as individual layers of the total display. As a consequence, more complex time series visualizations can be built from the “base” visuals.
Each visual can be assigned to either the left or right Y axes, allowing multiple scales to be represented.
For example, the following visualization includes:
q Candle Stick Graph – Showing the distribution of prices (OHLC)
q Line Graphs – Showing moving averages of the closing price
q Bar Graph – Showing traded volume across the period
q Spread Graph – Showing a price band across the period.
Each of the visuals has a defined “Z” order, which in this case places from back to front:
Spread, Bar, Candle Stick, Line
