Dashboard example in need of update

Using the sonarqube-prometheus-exporter-1.0.0.jar, with SonarQube 8.9+ (currently running 9.2.4-developer edition) we are seeing metrics rendered as:

# HELP sonarqube_bugs Bugs
# TYPE sonarqube_bugs gauge
sonarqube_bugs{key="npvr-nextgen-entitlement-lib",name="entitlement-lib",} 0.0
sonarqube_bugs{key="udf-danube-transformer",name="danube-distro-udf",} 0.0
sonarqube_bugs{key="voice-ga-c2c-service",name="voice-ga-c2c-service",} 14.0
.
.
.
# HELP sonarqube_coverage Coverage by tests
# TYPE sonarqube_coverage gauge
sonarqube_coverage{key="npvr-nextgen-entitlement-lib",name="entitlement-lib",} 85.0
sonarqube_coverage{key="udf-danube-transformer",name="danube-distro-udf",} 49.8
sonarqube_coverage{key="voice-ga-c2c-service",name="voice-ga-c2c-service",} 77.1
sonarqube_coverage{key="maxwebapp-2.0",name="Max Web App",} 0.0
.
.
.
(and so on...)

Your grafana_config.json uses an expression like this:

      "targets": [
        {
          "expr": "sonar_bugs{name=\"$projectName\"}",
          "format": "time_series",
          "hide": false,
          "intervalFactor": 1,
          "refId": "A"
        }
      ],

I've tried using an alternate set of expressions:

      "targets": [
        {
          "expr": "sonar_bugs{key=\"$projectKey\"}",
          "format": "time_series",
          "hide": false,
          "intervalFactor": 1,
          "refId": "A"
        }
      ],

Since our data-set contains 132 names, but 156 keys, so I chose to represent the set that way. However, in Grafana, it will only render the first 9 rows, with the remainder showing "No Data"
I am at a loss as to how this is happening.
