When a line style that is used by a chart is modified afterwards e.g. in calc, the modified line style is not automatically adopted by the chart and can even not be manually applied by editing the chart.
Steps to reproduce:
1. Calc: Draw a line and define its line style to be a new "line style X"
2. Calc: Create a chart, enter the chart and format its major grid to use "line style X" (BTW: When a bar chart is created based on no data at all, the resulting empty bar chart is spoiled after returing back to calc)
3. Exit the chart, return to calc and redefine "line style X"
The line style of the major grid of that chart remains unchanged. Even when editing the existing chart, the new "line style X" cannot be applied.
The "line style X" in the chart should automatically adjust to the changed settings of that line style. At least, when editing the chart manually and redefining the line style, the modified "line style X" should be taken into account.
Operating System: openSUSE
Version: 18.104.22.168 release
Thanks for reporting.
I think more in general, chart makes no use of any style.
Which indeed would be rather convenient.
So you could change the subject of the issue to "styles do not work for charts" or something?
(Couldn't immagine that there wasn't a report for this already ...)
