Hi Viz,
I am creating on app using GWT and Viz API.
The scenario is as follows:
1. The page has a search panel and a chart panel
2. When user selects some search criteria and clicks search, the
request goes to server and the responded data is rendered to the
chart. Now this piece of code to create chart is on the fly. The chart
is created everytime the response is received for the new search
criteria and hence I have to load the API on each new search.
I think, the the code is retricting the API to reload newly.
Here is the code snippet:
tempColumnChart.setPixelSize(500, 500);
mainChartVPanel.add(tempColumnChart);
mainChartVPanel.setCellHorizontalAlignment(tempColumnChart,
HasHorizontalAlignment.ALIGN_CENTER);
mainChartVPanel.setCellVerticalAlignment(tempColumnChart,
HasVerticalAlignment.ALIGN_TOP);
mainChartVPanel.setCellWidth(tempColumnChart,
"100%");
mainChartVPanel.setCellHeight(tempColumnChart,
"100%");
flexTablePanel = new
FlexTablePanel(ChartPanel.this,
mainChartType);
flexTablePanel.createPanel();
mainChartVPanel.add(flexTablePanel);
mainChartVPanel.setCellHorizontalAlignment(flexTablePanel,
HasHorizontalAlignment.ALIGN_LEFT);
mainChartVPanel.setCellVerticalAlignment(flexTablePanel,
HasVerticalAlignment.ALIGN_BOTTOM);
}
};
try {
VisualizationUtils.loadVisualizationApi(onLoadCallback,
ColumnChart.PACKAGE);
} catch (Exception e) {
GWT.log("ERROR");
}
Thanks
Ankit
