Dragging a chart loses color of filled objects Posts

Hello,

I need to make a chart draggagle. The chart can drag but as it does the colors of filled object (e.g., the bar chart) are cleared. As an example, I took a sample chart (javascript_char_bar_series.htm) and made it draggable by adding two lines. The complete code is below.

<script type=”text/javascript” src=”../../jqwidgets/jqxdragdrop.js”></script>
$(“#chartContainer”).jqxDragDrop();

I am not sure what I may be missing and I would appreciate any ideas.

Thanks,

Hello rmunoz10,

Here is how to fix this issue:
```
$('#chartContainer').jqxDragDrop({ onDragEnd: function () {
    $('#chartContainer').jqxChart('update');
}
});
```
Best Regards,
