Apexcharts.js: Feature Request: Public methods for toggling Series data. (Like clicking legend)

[jchamb]

Is your feature request related to a problem? Please describe.
Its common to build custom legends for better display when there are a large amount of series data. eg. content categorization with 16 categories. Typically we'll build a custom dropdown similar to https://codepen.io/elmahdim/pen/hlmri with an additional option to deselect (hide) all.

Currently we build custom filters to remove the deselected items and update the series data. This works without any issue but seems like a hack.

Describe the solution you'd like
Public Methods for show/hide/toggle should be added allow you to pass the series name that will hide the data just like if you clicked the built in legend series name.

Describe alternatives you've considered
Filters series data based on custom legend options and then update the series data.

As another reference point for a similar library, c3 exposes a single toggle method on the chart. Example https://c3js.org/samples/legend_custom.html

Interesting. The fact that legends are drawn by SVG elements (unlike tooltips which are drawn by HTML elements) makes customizing the legend a bit harder. Some users also faced issues in legend placements when there are too many items in legend.

I will surely work on this feature request in the upcoming releases.
Thanks for the suggestion

+1.
I love that tooltips are HTML, so easy to customize, so HTML legend would be great as well.

Released a patch release 2.1.4 to support toggleSeries() programmatically.

chart.toggleSeries('seriesName')
