Still a bug on 2.0.0-beta.0

[guykatz]

code explicitly uses label-size only for bar type label generation for some reason.
trend labels inherit their size from their g element which is a hard coded 8px in the code.
can be bypassed via css.

A little workaround:

<v-sparline ref="sparkline" ...></sparkline>

mounted() {
  const textElements = this.$refs.sparkline.$el.querySelectorAll('text');
  for (const textElement of textElements) {
    textElement.style.fontSize = '8px';
  }
}
