UltraChart StackedColumnChart tooltip questions
posted

This is the first time I have ever worked with a chart of any kind and I am struggling a bit to find a way to do the simple things I want to do.  I know there must be a property somewhere, but I have not found it.  I am using a stacked column chart.  The first issue that I am trying to resolve is when there are multiple  data values stacked, when I hover over each area, the tooltip displays a cumulative number (a sum) as you move up the stack instead of displaying the actual data value for that area.  For example, if I have a stack made up of 3 areas, the first value is 5, the second value is 10 and the third value is 5, when I hover over the bottom area, the tooltip is 5, but when I hover over the second area, the tooltip is 15.  I expect this to be 10.  When I hover over the third area, the tooltip is 20.  I expect this value to be 5.  What do I need to do to get this expected behavior?  Also, I need to add some additional text to the tooltip and see that I should be able to use the FillSceneGraph method to accomplish this, but I’m having difficulty finding the primitives for the boxes that make up my stack.  Is there a good tutorial somewhere that will enable me to familiarize myself with the stacked column chart and how to work with it?  I have been through the forum and I’m still going through it, but thought I would go ahead and get my questions out there to see if I could get some help.  Thanks, Sabrina
