Populating ofcgwt chart with data from the server

[Halabe]

Hi,

I created a Pie Chart using ofcgwt.

I want to populate this chart from a data that I am getting from the server using RPC.

The chart is only displayed when created and I am not able to refresh it neither from onSuccess of CallBack method nor from onClick of ClickHandler.

I tried the below and my chart is always empty.

Any idea?

ChartWidget    chart1 = new ChartWidget();
WidgetCanvas      wCanvas = new WidgetCanvas(chart1);




chartsService
                .getData(new AsyncCallback<HashMap<String, Integer>>() {
                    public void onFailure(Throwable caught)
                    {
                        System.out.println("Error Fetching TasksDue Data");
                    }

                    public void onSuccess(HashMap<String, Integer> result)
                    {
                        chart1 = new ChartWidget();
                        ChartData cd1 = new ChartData(chartTitle
                                .getDisplayValue(),
                                "font-size: 14px; font-family: Verdana; text-align: center;");
                        cd1.setBackgroundColour("#ffffff");
                        PieChart pchart1 = new PieChart();
                        pchart1.setTooltip("$#val#");
                        pchart1.addSlice(result
                                .get(ChartsConstants.TasksDueDiff.ONTIME),
                                ChartsConstants.TasksDueDiff.ONTIME);
                        pchart1.addSlice(result
                                .get(ChartsConstants.TasksDueDiff.ONEWEEK),
                                ChartsConstants.TasksDueDiff.ONEWEEK);
                        pchart1.addSlice(result
                                .get(ChartsConstants.TasksDueDiff.MOREWEEK),
                                ChartsConstants.TasksDueDiff.MOREWEEK);
                        cd1.addElements(pchart1);
                        chart1.setSize("100%", "100%");

                        HTML label1 = new HTML(
                                "<u>TASKS DUE DATE PERCENTAGE Chart</u>");
                        label1.setWidth("100%");
                      label1.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_CENTER);

                        chart1.setChartData(cd1);
                        wCanvas.removeChild(wCanvas);
                        wCanvas.addChild(chart1);
                    }
                });

    formLayout.addMember(wCanvas);

I closed this issue.

I had an error on the server side which was not catched.
