Best Practices

• Support ordinal values in XY components by returning the data index in the x accessor and providing a tickFormat to the VisAxis source

<script setup lang="ts">
const x = (d, i: number) => i
const tickFormat = (i: number) => data[i].category
</script>

<template>
  <VisXYContainer :data="data">
    <VisStackedBar :x="x" :y="d => d.value" />
    <VisAxis type="x" :tick-format="tickFormat" />
  </VisXYContainer>
</template>

• Define custom SVG gradients or patterns using the svgDefs property on VisXYContainer or VisSingleContainer source

<template>
  <VisXYContainer :svg-defs="gradientDef">
    <VisArea :x="d => d.x" :y="d => d.y" color="url(#gradient-id)" />
  </VisXYContainer>
</template>

• Display continuous lines across missing data points by filtering null values and passing the dataset directly to VisLine instead of the container source

<template>
  <VisXYContainer>

    <VisLine :data="data.filter(d => d.value !== null)" :x="x" :y="y" />
  </VisXYContainer>
</template>

• Attach events to axis ticks or other sub-elements using the events prop and component-specific selectors source

<script setup lang="ts">
import { VisAxisSelectors } from '@unovis/vue'
const axisEvents = {
  [VisAxisSelectors.tick]: {
    click: (val: number) => console.log('Clicked tick:', val)
  }
}
</script>

<template>
  <VisAxis type="x" :events="axisEvents" />
</template>

• Wrap Unovis components in <ClientOnly> when using Nuxt or SSR to prevent errors from top-level document or window references source

<template>
  <ClientOnly>
    <VisXYContainer :data="data">
      <VisLine :x="x" :y="y" />
    </VisXYContainer>
  </ClientOnly>
</template>

• Enable tooltips or interactions on TopoJSON map areas using the feature selector source

<script setup lang="ts">
import { VisTopoJSONMapSelectors } from '@unovis/vue'
const triggers = {
  [VisTopoJSONMapSelectors.feature]: d => d.properties.name
}
</script>

<template>
  <VisTopoJSONMap :triggers="triggers" ... />
</template>

• Fix clipped top or bottom axis labels by increasing the margin property on the VisXYContainer source

<template>

  <VisXYContainer :margin="{ top: 10, right: 10, bottom: 10, left: 10 }">
    <VisStackedBar ... />
  </VisXYContainer>
</template>

• Use tickTextWidth on VisAxis to enable automatic label wrapping and trimming for long axis labels source

<template>
  <VisAxis type="x" :tick-text-width="100" />
</template>

• Display multiple colors within a single legend bullet by passing an array to the color property of a legend item source

<script setup lang="ts">
const items = [
  { name: 'Multi-segment', color: ['#ff0000', '#00ff00', '#0000ff'] }
]
</script>

<template>
  <VisBulletLegend :items="items" />
</template>

• Programmatically control crosshair visibility and position using the forceShowAt property for custom sync or interaction logic source

<template>

  <VisCrosshair :force-show-at="{ x: 1707093300 }" />
</template>
