legend not displayed for radar Angular-chart.js

Question

I'm trying to create a radar chart using angular-chart js and chartjs 2.1. I was able to display the graph but not the legend. would you help me to display it. here is a plunker for what I've done

<canvas id="area" class="chart chart-radar" chart-data="data"
                  chart-labels="labels" chart-options="options" chart-legend = "true"></canvas>

Answer 1

You didn't add series in your canvas tag, edited plunker.

<canvas id="area" class="chart chart-radar" chart-data="data"
                  chart-labels="labels" chart-options="options" chart-series="series" chart-legend = "true"></canvas>
