Hello,

I am trying to make a chart within ignition that would mimic a min max chart seen below.  
 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/b/b3cd728f57e36444e21b6011474edc903935660c.png)

I have found documentation for it here: [JFreeChart Class Library (version 1.0.19-fx)](http://www.jfree.org/jfreechart/api/javadoc_old/index.html?org/jfree/chart/renderer/category/MinMaxCategoryRenderer.html)

But i am uncertain as to how to use this renderer. We are already given the minimum and maximum values, along with the average. i just need to take it from the dataset and display it in chart form.

Any help would be great. Thanks
