示例1: deduceAttributes

/**
 * This function tries to deduce the structure of the dataSource based on the dimensions and measures defined within.
 * It should only be used when, for some reason, introspection if not available.
 * @param dataSource
 * @returns {Attributes}
 */
function deduceAttributes(dataSource: DataSource): Attributes {
  var attributeJSs: AttributeJSs = [];

  var timeAttribute = dataSource.timeAttribute;
  if (timeAttribute) {
    attributeJSs.push({ name: timeAttribute.name, type: 'TIME' });

  dataSource.dimensions.forEach((dimension) => {
    var expression = dimension.expression;
