Local Rowset &oRowset;
Local Chart &oChart;
&oChart = GetChart(IB_PGLT_NOD_VW.IB_COUNT1);
&oRowset = GetLevel0()(1).GetRowset(Scroll.TEST_CHART_TAB);
MessageBox(0, "", 0, 0, "pagefieldname" | %Page);
MessageBox(0, "", 0, 0, &oRowset(2).TEST_CHART_TAB.TEST_TRANS_DESCR.Value);
&oChart.SetData(&oRowset);
&oChart.Width = 400;
&oChart.Height = 300;
&oChart.Type = %ChartType_2DStackedBar;
&oChart.SetDataYAxis(TEST_CHART_TAB.TEST_TRANS_DESCR);
&oChart.SetDataXAxis(TEST_CHART_TAB.TEST_TRANS_AMOUNT);

希望对你有帮助
我用如下的代码生成Chart，没有问题。你可以尝试一下SetData时，直接指定Record，不用Rowset
&oChart.SetData(Record.ACT_CHART_V);
REM 设置Chart对应的数据表;
&oChart.SetData(Record.ACT_CHART_V);
REM 设置Chart类型;
&oChart.Type = %ChartType_2DBar;
REM 设置Chart Title信息;
GetChartTitle("A_CHART", &strTitle, &strXTitle, &strYTitle);
&oChart.MainTitle = &strTitle;
&oChart.XAxisTitle = &strXTitle;
&oChart.YAxisTitle = &strYTitle;
REM 设置Chart的Data Series;
&oChart.SetDataSeries(ACT_CHART_V.HC_TYPE);
REM 设置Chart的X Axis Data;
&oChart.SetDataXAxis(ACT_CHART_V.MONTH);
REM 设置Chart的X Axis Label;
&xArray = CreateArrayRept("", 0);
&oRowset = GetLevel0()(1).GetRowset(Scroll.ACT_CHART_V);
For &I = 1 To &oRowset.ActiveRowCount
&VALUE = &oRowset.GetRow(&I).GetRecord(Record.ACT_CHART_V).GetField(Field.MONTH).LongTranslateValue;
&xArray [&I] = &VALUE;
End-For;
&oChart.SetXAxisLabels(&xArray);
REM 设置Chart的Y Axis Data;
&oChart.SetDataYAxis(ACT_CHART_V.HEADCOUNT);
