Bug 141248 Script: Set axis title background color, axis title can be covered.
Script: Set axis title background color, axis title can be covered. Steps: 1.Create a bar chart 2.Script:function beforeDrawAxisTitle(axis, title, scriptContext) { importPackage(Packages.org.eclipse.birt.chart.model.attribute); importPackage(Packages.org.eclipse.birt.chart.model.attribute.impl); { if (axis.getType() == AxisType.LINEAR_LITERAL) title.setVisible(false);} title.getCaption().getColor( ).set( 208, 32, 0); title.getCaption().getFont().setItalic(true); title.getCaption().getFont().setRotation(30); title.getCaption().getFont().setStrikethrough(true); title.getCaption().getFont().setSize(14); title.getCaption().getFont().setName("Arial"); title.getOutline().setVisible(true); title.getOutline().setThickness(3); title.setBackground(ColorDefinitionImpl.ORANGE()); } 3.Preview Actual Results: 1.Axis title can be covered Expected Results: 1.Axis title is visible.
