title: Oracle APEX - How to hide tooltip for one series in a stacked bar chart
body: <p>I am using Oracle APEX 19.1.0.00.15 and I have a question regarding tooltips for a stacked bar chart. I have created a stacked bar chart that consists of three series, but I would only like for the tooltip to be rendered for two of the series. I see that there is an option in the chart's Attributes section to hide or show the tooltip for the chart as a whole, but not for individual series within the chart. I have tried to find the relevant JavaScript for the tooltip in the Oracle JavaScript Extension Toolkit API Reference <a href="http://https://www.oracle.com/webfolder/technetwork/jet/jsdocs/oj.ojChart.html" rel="nofollow noreferrer">http://https://www.oracle.com/webfolder/technetwork/jet/jsdocs/oj.ojChart.html</a> but I was not able to find anything useful. Does anyone have any advice for how to achieve this?</p>
  
  <p>Thank you.</p>
