Charts. creating and other

[Mike_javaJunior]

Hi everyone.
I'm trying to make a simple example of chart just to see it works but it doesn't.
help me please. here is the code:

public class ExampleChart extends ContentPanel{

    public ContentPanel createChart(){


        setHeading("Horizontal Bar chart");
        setFrame(true);
        setSize(550, 400);
        setLayout(new FitLayout());


        String url = "/gxt/chart/open-flash-chart.swf";
        final Chart chart = new Chart(url);


        chart.setBorders(true);
        chart.setChartModel(getHorizontalBarChartModel());


        add(chart);
        return this;
    }


    public ChartModel getHorizontalBarChartModel()
    {
        //Create a ChartModel with the Chart Title and some style attributes
        ChartModel cm = new ChartModel("Students by Department", "font-size: 14px; font-family:      Verdana; text-align: center;");


        XAxis xa = new XAxis();
        //set the maximum, minimum and the step value for the X axis
        xa.setRange(0, 200, 50);
        cm.setXAxis(xa);


        YAxis ya = new YAxis();
        //Add the labels to the Y axis
        ya.addLabels("CSE", "EEE", "CE", "ME","CHE");
        ya.setOffset(true);
        cm.setYAxis(ya);


        //create a Horizontal Bar Chart object and add bars to the object
        HorizontalBarChart bchart = new HorizontalBarChart();
        bchart.setTooltip("#val#Students");
        bchart.addBars(new HorizontalBarChart.Bar(60, "#ffff00"));
        //different color for different bars
        bchart.addBars(new HorizontalBarChart.Bar(180, "#0000ff"));
        bchart.addBars(new HorizontalBarChart.Bar(180, "#00ff00"));
        bchart.addBars(new HorizontalBarChart.Bar(120, "#ff0000"));
        bchart.addBars(new HorizontalBarChart.Bar(120, "#333ccc"));


        //add the bchart as the Chart Config of the ChartModel
        cm.addChartConfig(bchart);
        cm.setTooltipStyle(new ToolTip(ToolTip.MouseStyle.FOLLOW));
        return cm;
    }


}

I've added a string

 <script type="text/javascript" language='javascript' src='/gxt/flash/swfobject.js'></script>

to the .html file of my project and I've added

 <inherits name="com.extjs.gxt.charts.Chart"/>

to the .gwt.xml file.
as a result I don't see anything. It shows only empty frame with the heading. I'm shure that swfobject.js and open-flash-chart.swf are in their places.
so help me please

OMG!!! it's so fun...))) I've forgotten I work with flash and I didn't have adobe flash plugin for the browser))) So, again I worked it out myself. It's very useful to post the porblem to the frum. As one of the members of this forum said, you can look at your problem from the other side.
