Hello I am working with the analytics data api to get some required data.

I have built up ~8 Google\Analytics\Data\V1beta\RunReportRequest objects that give me the required data.

But for my use case I need to make compare data from 2 date ranges. So I decided to look into cohort reports and see if they fit my use case.

    (new RunReportRequest())
        ->setProperty('properties/' . $property_id)
        ->setDimensions([
            new Dimension([
                'name' => 'cohort',
            ]),
            new Dimension([
                'name' => 'cohortNthDay',
            ])
        ])
        ->setMetrics([
            new Metric([
                'name' => 'cohortActiveUsers',
            ]),
        ])
        ->setCohortSpec(
            (new CohortSpec())
                ->setCohorts([
                    (new Cohort())
                        ->setDimension(
                            'firstSessionDate'
                        )
                        ->setDateRange(
                            new DateRange([ // format YYYY-MM-DD
                                'start_date' => '2023-12-01',
                                'end_date' => '2023-12-01',
                            ])
                        )
                ])
                ->setCohortsRange(
                    (new CohortsRange())
                        ->setGranularity(1)
                        ->setStartOffset(0)
                        ->setEndOffset(5)
                )
        ),

This is how my request is currently being built.

this is the output for $response->serializeToJsonString()

{
    "dimensionHeaders": [
        {
            "name": "cohort"
        },
        {
            "name": "cohortNthDay"
        }
    ],
    "metricHeaders": [
        {
            "name": "cohortActiveUsers",
            "type": "TYPE_INTEGER"
        }
    ],
    "rows": [
        {
            "dimensionValues": [
                {
                    "value": "cohort_0"
                },
                {
                    "value": "0000"
                }
            ],
            "metricValues": [
                {
                    "value": "13"
                }
            ]
        }
    ],
    "rowCount": 1,
    "metadata": {
        "currencyCode": "EUR",
        "timeZone": "Europe\/Amsterdam"
    },
    "kind": "analyticsData#runReport"
}

When I am expecting more values similair to
https://developers.google.com/analytics/devguides/reporting/data/v1/advanced#cohort_report_examples

I have tried these options to try and get a different output:

• Many different start dates
• Weekly/Monthly granularity
• Many different start/end offsets

But I keep getting similair response data. Does anyone know why?
