# Bubble Chart V2

> Bubble Chart V2 lets you control bubble size using a measure. Learn when it's available, data requirements, and why it might be disabled.

**Bubble Chart V2** lets you control **bubble size** using a **measure** (e.g., sum of revenue, count of orders), so each point's size reflects a numeric value. This is in addition to the X and Y axes.

***

## Data Requirements

To use Bubble Chart V2, you need:

| Axis       | What to configure                                                                 |
| ---------- | --------------------------------------------------------------------------------- |
| **X-axis** | A dimension or measure (e.g., category, date, or numeric value)                   |
| **Y-axis** | A dimension or measure                                                            |
| **Size**   | A **measure** that determines bubble size (e.g., `SUM(revenue)`, `COUNT(orders)`) |

You need at least **one dimension** and **two measures** — one for an axis and one for bubble size.

***

## How to Use Bubble V2

1. Create or edit a metric with at least one dimension and two or more measures.
2. Select **Bubble Chart V2** (or "Bubble v2") from the chart type list.
3. In chart settings, assign a **measure to bubble size** (look for a "Bubble size" or "Size measure" setting).
4. Save the metric.

## Why Bubble V2 Might Be Disabled

If you don't see Bubble V2 in the chart type list or it's grayed out:

<AccordionGroup>
  <Accordion title="Missing size measure" icon="ruler">
    The chart type requires a measure assigned for bubble size. If no measure is configured for size, the option may be unavailable.

    **Fix:** Add a second measure to your metric and assign it to the bubble size setting.
  </Accordion>

  <Accordion title="Not enough dimensions or measures" icon="chart-scatter">
    You may need at least one dimension (or axis) and two measures.

    **Fix:** Add the required columns to your metric configuration.
  </Accordion>

  <Accordion title="Context or plan limitation" icon="lock">
    Bubble V2 may be hidden in certain embed modes, workspaces, or plans.

    **Fix:** Check whether your environment or plan supports this chart type, or contact support.
  </Accordion>

  <Accordion title="Data shape not recognized" icon="table">
    In some cases, certain metrics or data shapes filter out Bubble V2 from the chart type selector.

    **Fix:** Try a metric that has clear X, Y dimensions and a numeric measure for size.

## Summary

| Topic         | What to know                                                                                 |
| ------------- | -------------------------------------------------------------------------------------------- |
| Data needed   | X, Y, and a **measure for bubble size**.                                                     |
| Why disabled? | Usually: no size measure set, or not enough dimensions/measures. Sometimes: context or plan. |
| What to do    | Add a measure and assign it to bubble size. If still disabled, check data shape and plan.    |
