AxisChart
public AxisChart(IAxisDataSeries iAxisDataSeries, ChartProperties chartProperties, AxisProperties axisProperties, LegendProperties legendProperties, int pixelWidth, int pixelHeight) Constructor- Parameters:
iAxisDataSeries

Method Details
-
getIAxisDataSeries
- Returns:
- IAxisDataSeries
-
createAxisChartDataProcessor
ScatterPlots create a subclass of AxisChartDataProcessor so we need this method so we can overload it.- Returns:
- AxisChartDataProcessor
-
setupDataAxisProperties
protected NumericTagGroup setupDataAxisProperties(Axis axis, DataAxisProperties dataAxisProperties, AxisChartDataProcessor axisChartDataProcessor, FontRenderContext fontRenderContext) Once we determine which axis is the data axis, the logic to set it up is the same whether it is a horizontal or vertical plot.- Parameters:
dataAxisProperties
-axisChartDataProcessor
-fontRenderContext
-- Returns:
- NumericTagGroup need to set this on the right axis
-
setupAxis
protected void setupAxis(AxisChartDataProcessor axisChartDataProcessor, FontRenderContext fontRenderContext) throws ChartDataException - Parameters:
axisChartDataProcessor
-fontRenderContext
-- Throws:
ChartDataException
-
sizeAndPositionAxis
private void sizeAndPositionAxis(float xAxisWidth, float yAxisHeight, float chartTitleHeight) Finalizes the size of both Axis and sets the origin position- Parameters:
xAxisWidth
-yAxisHeight
-chartTitleHeight
-
-
deriveAxisValues
protected void deriveAxisValues() -
renderChart
Implement the method to render the Axis based chart- Specified by:
renderChart
in classChart
- Throws:
ChartDataException
PropertyException
- there are several validations done to aid in development of the charts.
-
overlayCharts
Draws the charts over the axis. We have to render in a specific order so combo charts get drawn correctly- Throws:
PropertyException
ChartDataException
-
validateHorizontalPlot
Currently, we only support the bar chart types being horizontal, and you can not have a horizontally plotted bar chart in a combo chart.- Throws:
PropertyException
-
allowHorizontalPlot
private boolean allowHorizontalPlot()We only allow horizontal plots for the Bar Chart types in this release.- Returns:
- boolean
-
getAxisProperties
-
getXAxis
-
getYAxis
-
toHTML
Enables the testing routines to display the contents of this Object. Override Chart implementation as PieCharts use AreaProperties directly rather than a child.- Specified by:
toHTML
in interfaceHTMLChartTestable
- Overrides:
toHTML
in classChart
- Parameters:
htmlGenerator
-imageFileName
-imageMap
- if this is NULL we are not creating image map data in html
