SVG does not have the xaxisTickmarksCount property


Posted by Anthony Kuma at 00:22 on Monday 24th November 2025 [link]
Howdy, I'm converting canvas to svg and there is no xaxisTickmarksCount.
I use it to denote 15 min intervals in an hour on the x axis, between each vertical line (backgroundGridVlinesCount).
Any chance of migrating xaxisTickmarksCount code into SVG?
Regards,
Anthony Kumarasinhe

The SVG charts have the following properties that you can use instead - they're a bit of a mouthful but they do the job:

Line charts:

xaxisLabelsPositionEdgeTickmarksCount

Bar charts:

xaxisLabelsPositionSectionTickmarksCount
