Chart only shown on page reload, but not when routing pages (via Vue router)

[laz95]

I have a component Report.vue which contains a line chart which displays when I reload the page, but doesn't when I navigate from home page to .../report using router.push(...).
Code:

<canvas id="mycanvas2" :count="testCases.length"></canvas>
      <div v-for="(testCase,index) in testCases" :key="testCase.name">
              <chartjs-line :labels="xAxisOption" :beginzero="true" :datalabel="testCase.name" ref="ch"
                            :backgroundcolor="graph.colors[index]" :bordercolor="graph.colors[index]"
                            :data="testCase.data" :bind="true" target="mycanvas2"></chartjs-line>
            </div>
