consider a use-case when we need two x-axes. both linked and showing the different labels on different x-axes based on business requirements.
users want to see some extra details in the x-axises label along with time.
users want to see the buy volume in the second graph data grouped and also want to see the buy marker (that, at this time, and with a price on the y-axis when the trade happened) without data grouping.
To make my point clear, Consider this demo project -> https://jsfiddle.net/sLtkfh2x/
I have put extra buy volume and marker. buy volume has data grouping and buy volume marker does not have data grouping.
The last buy volume and buy volume marker are not visible when the chart is loaded.
If I hide the market volume using a legend and played with the range using the navigator I could see garbaged labels on the second x-axis.
earlier in this discussion thread and as said in viewtopic.php?f=12&t=51074
, it is clarified that if I have only one x-axis (rather than 2 linked x-axis) and if I set the overscroll property then the issue is resolved.
but in a use-case, when we need 2 x-axes, this seems a bug in highcharts. If the whole range of data is supposed to be displayed then why hide any point?
first query: Is it a bug that the last buy volume and marker are not visible? to fix what is a workaround? and is it a bug that second x-axis labels are garbaged when hiding marker volume for some range?
I have posted a bug issue: https://github.com/highcharts/highcharts/issues/19243
but this posted GitHub issue is not related to the above point because the above-mentioned issue is for 2 linked x-axis with the last volume and marker are not visible.
Second point, earlier in this thread I mentioned a demo project: https://jsfiddle.net/9mr70ze2/
. my post starts with '@kamil.m, I am facing another issue.....'
This is also a bug because even if the linked x-axises are there and if I hide a series, highcharts should not garbage the labels because linking the x-axis has to do with x-axis extremes but it should not affect the labels ideally.
Second query: Is this also a bug?
Before I post the bug in GitHub, it is worth discussing over here.
