Charts not showing up in IE

[RJAIN]

I have a requirement of generating dynamic line charts in my application done in GWT. I have successfully implemented it and it works great on safari, firefox and of course, GWT hosted mode. However, in IE (both 7 & 8), it does not work. It does bring up a flash placeholder but does not display anything.

It would be great if someone could help me with this - else I will have to start looking at building charts from the scratch.

GWT 1.5.3
GWT Ext 2.0.5
Adobe Flash 10
IE 7 & 8

Note: I do see the charts getting rendered if I include the chart panel in Viewport [new Viewport(panel)], but that doesn't solve my purpose as I want the charts to show inside another panel in my application.

Any kind of help will be greatly appreciated.

Thank you.

RJAIN, can you please post your code?

Yes, appreciate your response.

This is the class generating the line charts:


import com.gwtext.client.data.ArrayReader;
import com.gwtext.client.data.FieldDef;
import com.gwtext.client.data.FloatFieldDef;
import com.gwtext.client.data.MemoryProxy;
import com.gwtext.client.data.RecordDef;
import com.gwtext.client.data.Store;
import com.gwtext.client.data.StringFieldDef;
import com.gwtext.client.widgets.Panel;
import com.gwtext.client.widgets.chart.yui.LineChart;
import com.gwtext.client.widgets.chart.yui.NumericAxis;
import com.gwtext.client.widgets.chart.yui.SeriesDefY;

public class GraphPanelFactory{
private static GraphPanelFactory graphPanelFactory;

private GraphPanelFactory(){}

public static GraphPanelFactory singleton(){
if(graphPanelFactory == null){
graphPanelFactory = new GraphPanelFactory();
}
return graphPanelFactory;
}

public Panel getViewPanel(Object[][] data, int size) {

Panel vPanel = new Panel();
//vPanel.setLayout(new VerticalLayout(15));

MemoryProxy proxy = new MemoryProxy(data);

FieldDef[] fieldDef = new FieldDef[size + 1];
fieldDef[0] = new StringFieldDef("month");
for (int t = 1; t < size + 1; t++) {
fieldDef[t] = new FloatFieldDef("lab" + (t - 1));
}

SeriesDefY[] yAxis = new SeriesDefY[size];
for (int k = 0; k < size; k++) {
yAxis[k] = new SeriesDefY("Lab" + k, "lab" + k);
}

RecordDef recordDef = new RecordDef(fieldDef);

ArrayReader reader = new ArrayReader(recordDef);
final Store store = new Store(proxy, reader);

store.load();

SeriesDefY[] seriesDef = yAxis;

NumericAxis currencyAxis = new NumericAxis();
currencyAxis.setMinimum(0);
final LineChart chart = new LineChart();
chart.setWMode("transparent");
chart.setStore(store);
chart.setSeries(seriesDef);
chart.setXField("month");
chart.setYAxis(currencyAxis);
chart.setDataTipFunction("getDataTipText");
chart.setExpressInstall("js/yui/assets/expressinstall.swf");
chart.setWidth(500);
chart.setHeight(400);

vPanel.add(chart);

return vPanel;

}

}

And following are the lines of code from the calling class:

...............
resultsHPanel.add(resultValuesVPanel);
resultsHPanel.add(GraphPanelFactory.singleton().getViewPanel(labData, 1))
.................

where resultsHPanel is a HorizontalPanel, which gets added to another VerticalPanel.

Looking forward to hearing from you soon,
Thank you.
