hide grid show chart

Hi, 
Currently both my flexgrid and fushionchart are showing.
What I wanted is to hide my grid and only show the fusionchart. If I change the width and height of my grid to 0. Both of them (grid and chart) are not showing up anymore. 
How can I hide only the grid?
 
pivotgrid[cardId] = new Flexmonster({
container: "#pivot-container" + cardId,
licenseKey: "???",
componentFolder: "assets/plugins/flexmonster/",
width: "0%",
height: "0%",
toolbar: true,
report: flex
});

var chartflex = new FusionCharts({
"type": selected_chart,
"renderAt": "fusionchartContainer" + cardId,
"width": "100%",
"height": "100%"
});
pivotgrid[cardId].fusioncharts.getData({
type: chartflex.chartType()
}, function (chartConfig) {
chartflex.setJSONData(chartConfig);
chartflex.render();
}, function (chartConfig) {
chartflex.setJSONData(chartConfig);
});
