Method Detail

getPriceRanges

java.util.Map<java.lang.String,Layer1PriceAxisRangeCalculatable.ResultPriceAxisInfo> getPriceRanges(java.lang.String alias,
                                                                                                    double linesCount,
                                                                                                    java.util.Map<java.lang.String,Layer1PriceAxisRangeCalculatable.InputPriceAxisInfo> inputInfo)

You can use PriceRangeCalculationHelper for existing implementations

Parameters:

alias - instrument alias

linesCount - number of visible horizontal lines, that can display labels. Note that this value is double.
Value 2.3 will means 2 visible lines, and 3/10 of distance between lines as empty space to the top

inputInfo - map, containing all indicators for this strategy and this alias (having determined limits. If there was no data for this indicator, it won't be passed here), and their value range

Returns:

map, where key set should be equal to inputInfo key set, and value represents desired range and labels for this indicator
