Class ColumnChartData

java.lang.Object

lecho.lib.hellocharts.model.AbstractChartData

lecho.lib.hellocharts.model.ColumnChartData

All Implemented Interfaces:

ChartData

public class ColumnChartData
extends AbstractChartData

Data model for column chart. Note: you can set X value for columns or sub-columns, columns are by default indexed from 0 to numOfColumns-1 and column index is used as column X value, so first column has X value 0, second clumn has X value 1 etc. If you want to display AxisValue for given column you should initialize AxisValue with X value of that column.
