JSON format for scatter chart datasource

[flippy]

Hi,

I woud like to pass a JSON datasource to a scatter chart but I could not find the proper format to set the X and Y coordinates of my points.

I saw this example to setup the data via API:

data.getX().setItem(0, 0, (-100));

data.getY().setItem(0, 0, (5));

What is the equivalent in a JSON format that I could pass to this function?

chart1.setDataSource(jsonData);

Cheers,

Flippy

There is not a specific JSON format for scatter (or multi series charts), but you have to use the fields map API to tell us how to use each field, e.g.

    var items = [{"X":5, "Y":15},{"X":6, "Y":9},{"X":8, "Y":18}];

    chart1.setDataSource(items);

    var fields = chart1.getDataSourceSettings().getFields();

    var field1 = new cfx.FieldMap();

    field1.setName("Y");

    field1.setUsage(cfx.FieldUsage.Value);

    fields.add(field1);

    var field2 = new cfx.FieldMap();

    field2.setName("X");

    field2.setUsage(cfx.FieldUsage.XValue);

    fields.add(field2);
