The chart-focused sibling of `get_report_data` and `get_report_pivot_data`: use this after `get_report` when you need the values actually displayed by the chart — categories, series, slices or points — rather than reconstructing them from raw rows or pivot cells. Bar, line and combo charts return categories and series; donut charts return a metric and slices; bubble charts return points. Pivot-backed charts use their relevant aggregates and subtotals, while raw-backed charts apply the chart's summing and percentage-normalization rules. The complete chart payload is returned in one call, with no pagination. A missing chart configuration, excessive cardinality, or a report too large to calculate raises a clear error. You only see reports you have access to. ## Parameters The report to read. Accepts the report's ObjectId (the id returned by list\_reports) or a case- and accent-insensitive substring of its name. A name matching no — or more than one — report raises a clear error; pass the full id to disambiguate. ## Response The response shape depends on the chart's type. `chart_type` is the discriminator; `data_source` reflects the underlying report configuration (`raw`, `chart` or `pivot_table`); `autosummed` is `true` when the chart summed values automatically to produce these totals. ### Bar, line and combo charts Deep link to open this report in the Qobra web app. One of: `bar`, `line`, `combo`. One of: `raw`, `chart`, `pivot_table`. The x-axis values, in the order the chart lays them out. One entry per plotted series. `values` is aligned to `categories` (same length, same order); `tooltip_values` mirrors it when the chart shows a secondary tooltip metric. One of: `bar`, `line`. The breakout category this series is split by, or `null` when the series isn't broken out. ### Donut charts Deep link to open this report in the Qobra web app. Always `donut`. One of: `raw`, `chart`, `pivot_table`. The field the donut is measuring. One entry per donut slice. ### Bubble charts Deep link to open this report in the Qobra web app. Always `scatter`. One of: `raw`, `chart`, `pivot_table`. One entry per plotted bubble. `value` sizes the bubble and is `null` when the chart doesn't use a size metric.
