Hi, I have a problema with my DragNode Chart. I have to remove an node, from the dataset and from the chart visualy. I just try clone de object returned by .setJSONDATA(), later i try remove the index and later i try update de JSON using .setJSONDATA. This code is called into a FC_ChartUpdated. Look an example for this code: function FC_ChartUpdated(chartId, dataIndex, datasetIndex){ if(remove){ //seted for other function chartJSONData = jQuery.extend(true, {}, FusionCharts(chartId).getJSONData()); chartJSONData.dataset[datasetIndex-1].data.splice(dataIndex-1,1); FusionCharts(chartId).setJSONData(chartJSONData); } } This works fine if i NOT DRAG any node before this i want remove. Exemple: If i drag the node 'A1', and remove this node. The chart works fine. But, if i drag the node 'A2', and later i drag the node 'A1' and try remove him, the chart rendered the node 'A2' (and the others) for the wrong coordinate X and Y. Exists an method of remove only one node per time? Thank you
