Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://guide.vico.patrykandpatrick.com/cartesian-charts/columncartesianlayer.md). # ColumnCartesianLayer Use [`ColumnCartesianLayer`](https://api.vico.patrykandpatrick.com/vico/compose/com.patrykandpatrick.vico.compose.cartesian.layer/-column-cartesian-layer/) to create column charts. Instantiate it via [`rememberColumnCartesianLayer`](https://api.vico.patrykandpatrick.com/vico/compose/com.patrykandpatrick.vico.compose.cartesian.layer/remember-column-cartesian-layer). Columns are drawn via [`LineComponent`](https://api.vico.patrykandpatrick.com/vico/compose/com.patrykandpatrick.vico.compose.common.component/-line-component/) instances provided by [`ColumnProvider`](https://api.vico.patrykandpatrick.com/vico/compose/com.patrykandpatrick.vico.compose.cartesian.layer/-column-cartesian-layer/-column-provider/). [`ColumnProvider.series`](https://api.vico.patrykandpatrick.com/vico/compose/com.patrykandpatrick.vico.compose.cartesian.layer/-column-cartesian-layer/-column-provider/-companion/series) creates a `ColumnProvider` instance that uses one `LineComponent` instance per series. You can create your own implementation for custom behavior, including styling columns individually based on their *y*-values, as in the [“Temperature anomalies (June)”](https://github.com/patrykandpatrick/vico/blob/stable/sample/charts/compose/src/commonMain/kotlin/com/patrykandpatrick/vico/sample/charts/compose/TemperatureAnomalies.kt) sample chart.

In `rememberColumnCartesianLayer`, you can also change column spacing. Data labels are supported. When multiple series are added, columns can be grouped horizontally or stacked. The [“Daily digital-media use (USA)”](https://github.com/patrykandpatrick/vico/blob/stable/sample/charts/compose/src/commonMain/kotlin/com/patrykandpatrick/vico/sample/charts/compose/DailyDigitalMediaUse.kt) sample chart uses stacking.

## `Transaction.columnModel` Column layers use [`ColumnCartesianLayerModel`](https://api.vico.patrykandpatrick.com/vico/compose/com.patrykandpatrick.vico.compose.cartesian.data/-column-cartesian-layer-model/) instances. When using [`CartesianChartModelProducer`](https://api.vico.patrykandpatrick.com/vico/compose/com.patrykandpatrick.vico.compose.cartesian.data/-cartesian-chart-model-producer/), add them via [`columnModel`](https://api.vico.patrykandpatrick.com/vico/compose/com.patrykandpatrick.vico.compose.cartesian.data/column-model): ```kt cartesianChartModelProducer.runTransaction { columnModel { series(1, 8, 3, 7) series(y = listOf(6, 1, 9, 3)) series(x = listOf(1, 2, 3, 4), y = listOf(2, 5, 3, 4)) } // ... } ``` Each [`series`](https://api.vico.patrykandpatrick.com/vico/compose/com.patrykandpatrick.vico.compose.cartesian.data/-column-cartesian-layer-model/-builder-scope/series) invocation adds a series to the `ColumnCartesianLayerModel` instance. Above, three series are added. `series` has three overloads (each of which accepts all `Number` subtypes): * a `vararg` overload that takes *y*-values and uses their indices as the *x*-values * an overload that takes a collection of *y*-values and uses their indices as the *x*-values * an overload that takes a collection of *x*-values and a collection of *y*-values of the same size ## Manual `ColumnCartesianLayerModel` creation When creating a [`CartesianChartModel`](https://api.vico.patrykandpatrick.com/vico/compose/com.patrykandpatrick.vico.compose.cartesian.data/-cartesian-chart-model/) instance directly, you can add a column-layer model by using [`build`](https://api.vico.patrykandpatrick.com/vico/compose/com.patrykandpatrick.vico.compose.cartesian.data/-column-cartesian-layer-model/-companion/build). This function gives you access to the same DSL that `columnModel` does. ```kt CartesianChartModel( ColumnCartesianLayerModel.build { series(1, 8, 3, 7) series(y = listOf(6, 1, 9, 3)) series(x = listOf(1, 2, 3, 4), y = listOf(2, 5, 3, 4)) }, // ... ) ``` --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://guide.vico.patrykandpatrick.com/cartesian-charts/columncartesianlayer.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
