My Situation:
Once the canvas is generated, I want to have a blank canvas area with no curves and no y-axis - surprisingly, it's working as expected.
Starting View:

Desired Outcome:
When I click on a label (like Dataset1), I expect to see both the curve and its corresponding y-axis displayed, but currently only the curve is visible.
Code Repository:
https://stackblitz.com/edit/angular-ng2-charts-toggle-axis-visibility-z7elmqUpon initial inspection, your code appears to be correct and I anticipated it would function properly. However, after some troubleshooting, I discovered that chart.getDatasetMeta(i).hidden returns null when the dataset is hidden and false when it is visible. As a result, adjustments need to be made to the beforeLayout callback function for it to operate correctly.
chartPlugins = [{
beforeLayout: chart =>
chart.data.datasets.forEach((ds, i) => {
let hidden = chart.getDatasetMeta(i).hidden !== false;
chart.config.options.scales.yAxes[i].display = !hidden;
})
}];
I recommend reviewing the updated StackBlitz for further details.
