NaN and overlapping on bar chart

[amitguptagwl]

When the value is 0 for some labels.

render: 'value' and render: 'percentage' both gives output labels in percentage only. Even if I don't set any label config in plugins, it automatically render chart with % labels.

        plugins: {
          labels: [
            {
              render: 'value',
              position: 'outside' // this prevents overlapping
            },
            {
              render: 'percentage'
            }
          ]
        }
