V-Calendar from vuetify don´t load my Events

Question

i want to create a Vuetify-Calendar in my Vue.js-Application.

This is how my calendar looks:

      <v-calendar
        class="mt-5 mb-5 rounded-xl"
        v-model="focus"
        ref="calendar"
        :weekdays="weekday"
        locale="de"
        :events="transformEvents"
        :show-month-on-first="false"
        color="primary"
        :type="type"
        :timezone="'Europe/Berlin'"
      >
      </v-calendar>

But the Timeline begins at 0 am. How i can change it. That the timeline is only from 8 am to 17pm
