## Bar and line combo chart: a React and Figma chart in four sizes

### What does a bar and line combo chart show?

A bar and line combo chart puts an amount as bars on the left axis and a rate as a line on the right axis, over the same periods. You see how volume and rate move together. Use it for new MRR and churn, orders and conversion, spend and return.

Chartory ships it as a Figma component and a React component with the same name. The code installs from the shadcn registry with one command and lands in your project as a file you own.

### What is the Bar and line combo component?

It is one **<BarAndLineCombo>** component. Its props are the Figma properties with the same names and values, and the props table above lists them. The data is one amount and one rate per period.

Sizes **XS**, **S**, **M** and **L** re-lay the chart out from the data instead of scaling it, so labels stay readable at every size.

### When should I use it?

- **Do the two series use different units?** Yes means the bar and line combo fits.
- **Is one of them an amount per period?** Yes means the bar and line combo fits.
- **Are there two series only?** Yes means the bar and line combo fits.

### When does another type fit better?

- **Same unit, one axis.** Use Multi-line chart instead.
- **Two rates, both continuous.** Use Multi-line chart instead.
- **A whole mix per period.** Use Stacked bars instead.

## Bar and line combo questions

### Does the Bar and line combo chart work with shadcn/ui?

Yes. It installs through the shadcn registry with the shadcn CLI, and the file lands in your project.

### How do I install it?

It is free in Hearth and MIT licensed: add the @chartory registry URL once, no token, then run npx shadcn add @chartory/bar-and-line-combo. The Installation guide has the steps.

### Can my coding agent install it?

Yes. Connect the Chartory MCP server and ask for the bar and line combo chart; the agent runs the same command and you review the diff.

### What data does it expect?

One amount and one rate per period. The sample data comes with the component, and the props table lists every field.

### Which sizes does it ship in?

XS, S, M and L, in Figma and in code. Each size is laid out again from the data, so text and lines keep their size.

### Is it in the Figma file too?

Yes. chart/046-combo-mrr-churn has the same properties as the component.

### Does it follow light and dark mode?

Yes. Every paint is a token, so the chart follows light and dark mode and the collection you pick.

### Which plan has the code?

None for Hearth: it is free in the public registry, no token. The Signal collection (@chartory/signal) comes with Code and Complete.
