Voronoi

Voronoi charts are used for visualizing proximity and influence by dividing space into distinct regions based on the distance to a set of points.

Basic

See the full API here. Typically composed with VictoryChart to create full charts.

      { x: 5, y: 7 },

Voronoi - Labels

Voronoi charts can be used to display labels using a label property in the dataset or by specifying a function to the labels prop.

    labels={({ datum }) =>
      `y: ${datum.y}`
    }
  />
</VictoryChart>

Voronoi - Tooltips

Tooltips can be added by using a VictoryTooltip component as the labelComponent.

    labels={({ datum }) => datum.y}
    labelComponent={<VictoryTooltip />}

</VictoryChart>

Voronoi - Circles

Voronoi charts can also be used to display circles around data points.

const data = [
  { x: 1, y: 2 },
  { x: 2, y: 3 },
  { x: 3, y: 5 },
  { x: 4, y: 4 },
  { x: 5, y: 7 },
];

function App() {
  return (
    <VictoryChart
      domain={{ x: [0, 5], y: [0, 7] }}
      theme={VictoryTheme.clean}
    >
      <VictoryVoronoi
        data={data}
        size={50}
      />
      <VictoryLine data={data} />
      <VictoryScatter data={data} />
    </VictoryChart>
  );
}

render(<App />);

Voronoi - Styles

Chart styling can be customized by using the theme or overriding the style prop on the component.

      { x: 4, y: 4 },
      { x: 5, y: 7 },

    style={{
      data: {
        stroke: "#ffffff",
        strokeWidth: 2,
        fill: "#2299ff",
        fillOpacity: 0.7,
      },
    }}
  />
</VictoryChart>

Voronoi - Events

Events can be handled by passing an array of event objects to the events prop on the component. Each event object should specify a target and an eventHandlers object. See the events guide for more information.

                          fill: "white",
                        },
                      };
                },
              },
            ];
          },
        },
      },
    ]}
    data={sampleData}
  />
</VictoryChart>

Standalone Rendering

Area charts can be rendered outside a VictoryChart.

<VictoryVoronoi
  theme={VictoryTheme.clean}

    { x: 1, y: 2 },
    { x: 2, y: 3 },
    { x: 3, y: 5 },
    { x: 4, y: 4 },
    { x: 5, y: 7 },
  ]}
/>

They can also be embeded in other SVG components by using the standalone prop.
