Hey @Jamie_Buck-Tomek, thanks for reporting this issue. I did some testing and so far I haven’t been able to reproduce the issue where stacked column charts aren’t working in Lightning in 16.1.4.
Here’s the page I’m using.
<skuid__page unsavedchangeswarning="yes" personalizationmode="server" showsidebar="false" showheader="false">
<models>
<model id="Opportunities" limit="" query="true" createrowifnonefound="false" datasource="salesforce" sobject="Opportunity">
<fields>
<field id="Amount"/>
<field id="StageName"/>
<field id="IsClosed"/>
<field id="CloseDate"/>
</fields>
<conditions/>
<actions/>
</model>
</models>
<components>
<skuid__chart model="Opportunities" maintitle="{{Model.labelPlural}}" type="column" uniqueid="sk-WPK-12885" stacking="true">
<dataaxes>
<axis id="axis1" title="Amount"/>
</dataaxes>
<categoryaxes>
<axis id="categories" categorytype="field" field="CloseDate" fillvals="true" dategranularity="calmonth"/>
</categoryaxes>
<serieslist>
<series valuefield="Amount" splittype="field" modelId="Opportunities" categoryField="CloseDate" splitfield="StageName"/>
</serieslist>
<colors/>
<legend layout="horizontal" halign="center" valign="bottom"/>
<styles>
<spacing/>
</styles>
</skuid__chart>
</components>
<resources>
<labels/>
<javascript/>
<actionsequences/>
</resources>
<background/>
<interactions/>
<surfaces/>
</skuid__page>
Let me know if there’s anything I’m missing… It looks like the chart is in a Skuid tab in a LIghtning tab? If you’re able to create a simplified version of your page that we can use for testing, that would be great. Check out this post for tips: How to create a good test page.
