Build custom dashboards with the Instana data source plugin for Grafana. The plugin is available on Grafana along with simple getting started instructions.
You can also find the plugin on Github.
Instana makes a semantic distinction between no-data represented as null and 0 as value. In order to avoid gaps in the Grafana dashboard, caused by the null values, open the Visualization and chose "null as zero" in the "Null value" drop down.
