| Field | Type | Description |
|---|---|---|
| chart_id | [bitdrift.public.unary.charts.v1.ChartIdentifier](bitdrift_public_unary_charts_v1_ChartIdentifier.md "bitdrift.public.unary.charts.v1.ChartIdentifier") | The identifier of the chart to fetch data for. |
| histogram_configuration | [bitdrift.public.unary.charts.v1.HistogramConfiguration](bitdrift_public_unary_charts_v1_HistogramConfiguration.md "bitdrift.public.unary.charts.v1.HistogramConfiguration") | Optional configuration for any histogram values within the chart. |
| insight_comparison_configuration | [bitdrift.public.unary.dashboards.v1.InsightComparisonConfiguration](bitdrift_public_unary_dashboards_v1_InsightComparisonConfiguration.md "bitdrift.public.unary.dashboards.v1.InsightComparisonConfiguration") | Optional configuration to indicate that this chart should compare two insights time series. |
| limit_strategy | [bitdrift.public.unary.charts.v1.LimitStrategy](bitdrift_public_unary_charts_v1_LimitStrategy.md "bitdrift.public.unary.charts.v1.LimitStrategy") | Optional limit strategy to use for this chart. Currently supported only for line charts. If omitted, a default top-K limit of 5 entries is used. |
| sankey_configuration | [bitdrift.public.unary.dashboards.v1.SankeyConfiguration](bitdrift_public_unary_dashboards_v1_SankeyConfiguration.md "bitdrift.public.unary.dashboards.v1.SankeyConfiguration") | Optional configuration for the sankey chart. |
| counter_configuration | [bitdrift.public.unary.dashboards.v1.CounterConfiguration](bitdrift_public_unary_dashboards_v1_CounterConfiguration.md "bitdrift.public.unary.dashboards.v1.CounterConfiguration") | Counter configuration for the chart. Currently this is only used for resolving which table type to show in the case of a group by query. |
| rate_configuration | [bitdrift.public.unary.dashboards.v1.RateConfiguration](bitdrift_public_unary_dashboards_v1_RateConfiguration.md "bitdrift.public.unary.dashboards.v1.RateConfiguration") | Rate configuration for the chart. Currently this is only used for resolving which table type to show in the case of a group by query. |
| time_series_display_mode | [bitdrift.public.unary.charts.v1.ChartMetadata.MetricChartMetadata.TimeSeriesDisplayMode](bitdrift_public_unary_charts_v1_ChartMetadata.md "bitdrift.public.unary.charts.v1.ChartMetadata.MetricChartMetadata.TimeSeriesDisplayMode")only one of time_series_display_mode, or table_display_mode, histogram_bar_chart_display_mode can be set | |
| table_display_mode | [bitdrift.public.unary.charts.v1.ChartMetadata.MetricChartMetadata.TableDisplayMode](bitdrift_public_unary_charts_v1_ChartMetadata.md "bitdrift.public.unary.charts.v1.ChartMetadata.MetricChartMetadata.TableDisplayMode")only one of table_display_mode, or time_series_display_mode, histogram_bar_chart_display_mode can be set | |
| histogram_bar_chart_display_mode | [bitdrift.public.unary.charts.v1.ChartMetadata.MetricChartMetadata.HistogramBarChartDisplayMode](bitdrift_public_unary_charts_v1_ChartMetadata.md "bitdrift.public.unary.charts.v1.ChartMetadata.MetricChartMetadata.HistogramBarChartDisplayMode")only one of histogram_bar_chart_display_mode, or time_series_display_mode, table_display_mode can be set | This is only valid if all time series in the chart are histograms. |
