I would like to display my data according to two attributes: symbol size using one attribute and the color ramp&amp;nbsp; according to second attribute. I know that it is possible to do in ArcMap, but in ArcGIS online I cannot find this option. Is it possible to do this in ArcGIS online?&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
