Sorry for the delay
Ok there are two options for you to fix this. At the moment both have some compromises:
1) use the imgstyle attribute of ecb to align the chart to the left:
imgstyle="float:left;" datatablecss="float:left;"
1a) Same as above but because the table does not align cleanly just hide it altogether:
imgstyle="float:left;" hidechartdata="true"
2) Wrap the ecb shortcode in a div that restricts the sandbox of the ecb chart:
<div align="left" style="width:50%;">
[ecb ...]
</div>
Note you can replace the 50% above with say, 200px (200 pixels wide)
I need to update the plugin with a general alignment parameter
