Hello, here's my problem: I've a Json connecton that recieve from a REST service, I perse them and I make an other Json string to get only the field that I want. I wanna make 2 charts; a piechart of the used extention, and a linechart for the usage in the past month. here's my json [{"extention":"zip","label":"9,09 %","value":6},{"extention":"rtf","label":"34,85 %","value":23},{"extention":"doc","label":"6,06 %","value":4},{"count":27,"day":"02/09"},{"count":1,"day":"02/08"},{"count":5,"day":"02/07"}][/code]I've seen that if I want to make 2 charts, i must have all the fields in every object. So I thought to make 2 other reports and put these into my summary reports with subreports. But the thing is that if I want to separate the data, i must separate the connection. So I tried to put into 2 params, 2 JsonDataSource but it won't work I tried for a week now, i depresed ... Can you help me ? regards Gilles

I've got a problem with the dataset function. I use the Netbeans plugin and a JsonDataSource. In fact I want to make 2 maybe 3 charts: - 1 pieChart - 1 lineChart When i tried without dataset, I've got an error who says: java.lang.IllegalArgumentException: Null 'key' argument. from these error, I understood that i must have the 2 data in each jsonobject... But here's my JSON: [{"extention":"zip","label":"9,09 %","value":6},{"extention":"rtf","label":"34,85 %","value":23},{"extention":"doc","label":"6,06 %","value":4},{"count":27,"day":"02/09"},{"count":1,"day":"02/08"},{"count":5,"day":"02/07"}][/code] I can change the json if I must ... Can you help me ?
