Overview

Provides developers with access to the compacting features.

Properties

average

Returns the average points set by the compactedBy property.

@property(nonatomic) CompactFormulaHandler average

Discussion

For example, if you want to compact data based on the average for a chart containing 1000 points and the CompactedBy property has a value of 2, the resulting plotted data will consist of 500 points. Each point in the new data will be the result of the average value of two adjacent datapoints from the original dataset.

ChartFX.h

first

Returns the first points set by the compactedBy property.

@property(nonatomic) CompactFormulaHandler first

Discussion

For example, if you want to compact data based on the first for a chart containing 1000 points and the CompactedBy property has a value of 2, the resulting plotted data will consist of 500 points. Each point in the new data will be the result of the first value of two adjacent datapoints from the original dataset.

Declared In


ChartFX.h

hiLowClose

Returns the high, low, and close points set by the compactedBy property.

@property(nonatomic) CompactFormulaHandler hiLowClose

Discussion

This is particularly useful when you want to compact data for a HighLowClose Chart.

For example, if you want to compact data based on the high, low, and close of a chart containing 1000 points and the CompactedBy property has a value of 2, the resulting plotted data will consist of 500 points. Each point in the new data will be the result of the high, low, and close values of two adjacent datapoints from the original dataset.

Declared In


ChartFX.h

last

Returns the last points set by the compactedBy property.

@property(nonatomic) CompactFormulaHandler last

Discussion

For example, if you want to compact data based on the last for a chart containing 1000 points and the CompactedBy property has a value of 2, the resulting plotted data will consist of 500 points. Each point in the new data will be the result of the last value of two adjacent datapoints from the original dataset.

Declared In


ChartFX.h

max

Returns the max points set by the compactedBy property.

@property(nonatomic) CompactFormulaHandler max

Discussion

For example, if you want to compact data based on the max for a chart containing 1000 points and the CompactedBy property has a value of 2, the resulting plotted data will consist of 500 points. Each point in the new data will be the result of the maximum value of two adjacent datapoints from the original dataset.

Declared In


ChartFX.h

min

Returns the min points set by the compactedBy property.

@property(nonatomic) CompactFormulaHandler min

Discussion

For example, if you want to compact data based on the min for a chart containing 1000 points and the CompactedBy property has a value of 2, the resulting plotted data will consist of 500 points. Each point in the new data will be the result of the minimum value of two adjacent datapoints from the original dataset.

ChartFX.h

openHiLowClose

Returns the open, high, low, and close points set by the compactedBy property.

@property(nonatomic) CompactFormulaHandler openHiLowClose

Discussion

This is particularly useful when you want to compact data for a OpenHighLowClose Chart.

For example, if you want to compact data based on the open, high, low, and close of a chart containing 1000 points and the CompactedBy property has a value of 2, the resulting plotted data will consist of 500 points. Each point in the new data will be the result of the open, high, low, and close values of two adjacent datapoints from the original dataset.
