Namespace: Comparison

CIQ. Comparison

Namespace for functionality related to comparison series.

Members

initialPrice :number|string

For relative comparisons, this is the starting (baseline) point.

Valid options are:

  • A number to specify an absolute amount to be used as the starting value for all percentage changes.
  • A string containing the symbol of an existing series to be used as the starting value for the comparisons (for instance "IBM"). Computations will then be based on the change from the first visible bar value for the selected symbol.
  • An empty string will compare against the baseline value of the main series (same as in "percent" scale).

See CIQ.ChartEngine#setChartScale for more details.

  • number | string
