Problem using my Group level function in a chart

Question

Post Author: LcdCyn
CA Forum: Charts and Graphs
I have created a function (StatePerRecord) that is displayed under the Details section to evaluate each records' state:
Here is my code:
If Not IsNull () Then    (    select         case "fail":            if (Not (IsNull ())) Then               "Passed"           else               "Failed"        case "pass":              "Passed"        default:             "Passed"     )
else      "NA"
I also have group section based on Record ID that groups the state record. In the header of the group footer I need to define summary function (StateSummary) such that
highest state from the state records should be the output here (excluding "NA" state). Here are the priorities:
  Highest - Failed
  Lowest - Passed
I want to use the StateSummary in a graph to show the Summarized State per Record ID.
I used Running Totals in my StateSummary function but I cannot see the field in the Chart expert.
P.S. I use Crystal Reports 10 Professional

Object (when acting as a map) uses toString() as a poor man's hashcode implementation, so you can get more-or-less the behavior you want by implementing the toString() method in your CIDate class and then storing the instances in an Object (rather than a Dictionary).
E.g., say your CIDate looks like this:
          public class CIDate {
            public var num:Number
            public function CIDate(num:Number) { this.num = num }
            public function toString():String { return num.toString(); }
You can use toString() as a comparison operator by keeping things in an Object instead of a Dictionary:
            var testDic:Object = {};
            var key1:ClDate = new ClDate(10000);
            var key2:ClDate = new ClDate(20000);
            var key3:ClDate = new ClDate(30000);
            var key4:ClDate = new ClDate(40000);
            testDic[key1] = 1;
            testDic[key2] = 2;
            testDic[key3] = 3;
            testDic[key4] = 4;
            var key:ClDate = new ClDate(20000);
            var retNum:Number = testDic[key];
Then retNum should be '2', as expected. This is sort of a hack, but it might work for what you're doing.
