Correctly alignment..
No..I'm not using GWT wrapper. Attached sample code:
package com.sample.tools.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.event.dom.client.ClickEvent;
import com.google.gwt.event.dom.client.ClickHandler;
import com.google.gwt.i18n.client.DateTimeFormat;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.VerticalPanel;
import com.google.gwt.visualization.client.AbstractDataTable;
import com.google.gwt.visualization.client.DataTable;
import com.google.gwt.visualization.client.VisualizationUtils;
import
com.google.gwt.visualization.client.visualizations.AnnotatedTimeLine;
public class GxtSample implements EntryPoint
{
private VerticalPanel chartPanel;
private AnnotatedTimeLine chart;
private DataTable chartData;
private AnnotatedTimeLine.Options options;
public void onModuleLoad()
{
Runnable onLoadCallback = new Runnable()
{
public void run()
{
chartPanel = new VerticalPanel();
chartPanel.add(createChart());
Button button = new Button("Change", new
ClickHandler() {
public void onClick(ClickEvent event) {
updateChart();
}
});
VerticalPanel vPanel = new VerticalPanel();
vPanel.add(button);
vPanel.add(chartPanel);
RootPanel.get().add(vPanel);
}
};
VisualizationUtils.loadVisualizationApi(onLoadCallback,
AnnotatedTimeLine.PACKAGE);
}
private AnnotatedTimeLine createChart()
{
chartData = DataTable.create();
chartData.addColumn(AbstractDataTable.ColumnType.DATE, "Date");
chartData.addColumn(AbstractDataTable.ColumnType.NUMBER,
"column11");
chartData.addColumn(AbstractDataTable.ColumnType.NUMBER,
"column12");
chartData.addRows(3);
DateTimeFormat dtf = DateTimeFormat.getFormat("yyyy-MM-dd");
chartData.setValue(0, 0, dtf.parse("2009-11-21"));
chartData.setValue(0, 1, 10);
chartData.setValue(0, 2, 20);
chartData.setValue(1, 0, dtf.parse("2009-11-22"));
chartData.setValue(1, 1, 11);
chartData.setValue(1, 2, 21);
chartData.setValue(2, 0, dtf.parse("2009-11-23"));
chartData.setValue(2, 1, 12);
chartData.setValue(2, 2, 22);
options = AnnotatedTimeLine.Options.create();
options.setDisplayAnnotations(false);
options.setDisplayZoomButtons(true);
options.setScaleType(AnnotatedTimeLine.ScaleType.ALLFIXED);
options.setLegendPosition(AnnotatedTimeLine.AnnotatedLegendPosition.SAME_ROW);
options.setAllowRedraw(true);
chart = new AnnotatedTimeLine(chartData, options, "600px",
"200px");
return chart;
}
private void updateChart()
{
chartData.removeColumns(0, 3);
chartData.addColumn(AbstractDataTable.ColumnType.DATE, "Date");
chartData.addColumn(AbstractDataTable.ColumnType.NUMBER,
"newCol");
chartData.addRows(2);
DateTimeFormat dtf = DateTimeFormat.getFormat("yyyy-MM-dd");
chartData.setValue(0, 0, dtf.parse("2009-11-21"));
chartData.setValue(0, 1, 110);
chartData.setValue(1, 0, dtf.parse("2009-11-22"));
chartData.setValue(1, 1, 111);
chart.draw(chartData, options);
}
