I'm not sure this is an intended implement or a bug. The behavior can reproduce with this example. https://codesandbox.io/s/vue-apexcharts-example-80f39 Steps to reproduce: - toggle a series on the legend - switch chart type by choosing different option on select control - See the legend state is reset, however the chart still display only two series. - Click again hidden series on legend, the series is still not able to display.
