Heatmap

A heatmap represents data as a matrix where individual values are represented as colors. Heatmaps can help you discover trends and understand complex datasets.

Structure

import "@gooddata/sdk-ui-charts/styles/css/main.css";
import { Heatmap } from "@gooddata/sdk-ui-charts";

<Heatmap
    measure={<measure>}
    rows={<attribute>}
    columns={<attribute>}
    config={<chart-config>}
    …
/>

The following example shows the supported config structure with sample values. For the descriptions of the individual options, see ChartConfig.

{
    xaxis: {
        visible: true,
        labelsEnabled: true,
        rotation: "auto"
    },
    yaxis: {
        visible: true,
        labelsEnabled: true,
        rotation: "auto"
    },
    legend: {
        enabled: true,
        position: "top"
    },
    dataLabels: {
        visible: "auto"
    },
    separators: {
        thousand: ",",
        decimal: "."
    }
}

Example

import "@gooddata/sdk-ui-charts/styles/css/main.css";
import { Heatmap } from "@gooddata/sdk-ui-charts";

import * as Ldm from "./ldm/full";

<div style={{ height: 300 }} className="s-heat-map">
    <Heatmap
        measure={Ldm.$TotalSales}
        rows={Ldm.LocationState}
        columns={Ldm.MenuCategory}
        onLoadingChanged={this.onLoadingChanged}
        onError={this.onError}
    />
</div>
