Dependency wheel in polar chart mode draws only half of the chart

[ollivihervuori]

Chart settings where the issue replicates:

Highcharts.chart('container',{
	"chart": {
		"type": "dependencywheel",
		"polar": true
	},
	"series": [
		{
			"data": [
				{
					"from": "A",
					"to": "B",
					"weight": 1
				}
			]
		}
	]
});

Expected behaviour

I'm not sure how the dependency wheel in polar chart mode could be drawn, but the way how it's currently drawn seems illogical.

Actual behaviour

Only half of the chart is shown:

Affected browser(s)

At least Chrome, but issue is likely not browser related.

Hi @ollivihervuori!

I agree it looks strange, but I do not know how the dependency wheel could work with a polar chart.
Do you have any use case and idea of how it might work?

[ollivihervuori]

Yeah, the dependency wheel is already a polar kind of chart, so perhaps it cannot be converted into polar coordinates in a meaningful way. I believe the pie chart just ignores the polar checkbox, so perhaps the dependency wheel could work similarly.

We have a software allowing users to set the chart type and whether it's a polar chart, so our users ended up seeing this strange dependency wheel. We will solve the issue by disabling the polar for the dependency wheel, so this is not a critical issue for us.

Thank you @ollivihervuori for the explanation!

I agree that the dependency wheel is already a polar kind of chart 😉
Let's ignore the polar property for this series.
