Hi @hubaksis!
The option onPoint.z
is working correctly, you can check it here: https://jsfiddle.net/BlackLabel/7bzg8tmh/ I am returning random values 10, 20, 30, or 40 and you can see, that the dimensions of pies are different. You're right, it's not documented and it should be here: https://api.highcharts.com/highmaps/series.map.onPoint
The option size
works, because you are using pie series: https://api.highcharts.com/highcharts/series.pie.size This is correct behaviour, because you can use properties from pie series in series on point pie.
Internal note:
We should add onPoint.z
to the API docs.
Hi @hubertkozik,
What's the meaning of onPoint.z
than?
If I return a constant value instead of your random value, then despite the value the size of the pie chart is the same.
See https://jsfiddle.net/Guest538/1e9Lpw3q/ and https://jsfiddle.net/Guest538/1e9Lpw3q/1/
The onPoint.z
is similar to bubble.data.z
value: https://api.highcharts.com/highcharts/series.bubble.data.z
Thanks, now it makes sense.
By trial and error I also figured out that onPoint
has properties minSize
and maxSize
, which are used by z
when calculating the size of the chart.
Example is here: https://jsfiddle.net/Guest538/wh9peozn/
While the documentation is being updated - can you please tell me if there is a way to make the pie chart grow when the map is zoomed in? Maybe it's also not in the docs yet :)
Thanks!
@hubaksis about minSize
and maxSize
there is another GH ticket: https://github.com/highcharts/highcharts/issues/19702 You're right, those options are working and should be documented also.
When it comes to making the pie chart grow when the map is zoomed in, I would classify it as a new Feature Request. It's not implemented right now into series-on-point
module. If you would like to, you can create a Feature Request as a new GitHub ticket.
This example "Map with overlaid pie charts" https://www.highcharts.com/demo/maps/map-pies uses
onPoint.z
property to set the size. However, returning any number from this function (like 10, 50, 200) does not change the pie chart size. See here: https://jsfiddle.net/Guest538/tyvwbs0r/1/ lines 240-243. Moreover, there is no mention ofz
property in the api docs here: https://api.highcharts.com/highmaps/series.map.onPointPossible workaround
Use
size
property. See https://jsfiddle.net/Guest538/vq0sgahw/1/ line 244Expected behaviour
Not sure what was the plan.
If
onPoint.z
property is supposed to be used, then it should work correctly and it should be mentioned in the docs. IfonPoint.z
property is not supposed to be used, then demo of "Map with overlaid pie charts" should not use it.Actual behaviour
Live demo with steps to reproduce
See here: https://jsfiddle.net/Guest538/tyvwbs0r/1/ lines 240-243.
