Hi guys,

I’ve noticed that in my application, the Rollover Modifier vertical line is rendering off-center compared to gridlines. I stack a couple of SciCharts on top of each other and they both utilise the Rollover. This is causing a funny look. Please see the attached screenshot for more info.

It also appears that the RolloverMarker is also rendering a little off-center with reference to the gridlines and the datapoints. I’ve attached a screenshot from the SciChart Examples for this one.

Hi miles,

We snap everything to the nearest pixel in SciChart so you might get a 1px offset occasionally on Point-Markers and Rollover lines etc… The gridline in the background of your chart doesn’t appear too crisp, perhaps there’s some Snap-to-device-pixels flag missing in our templates?

Is this a new issue to v2.0 or one that you have seen before?

Best regards,
Andrew

    Hi Andrew, The attachment shot on the left is prior to SciChart 2.0, and the one on the right is after the upgrade. From what I can see it's just a 2.0 issue. If it helps you debug, I've turned on the high quality rasterizer for sub-pixel rendering so that I can get anti-aliasing on my lines (it looks brilliant by the way!). I didn't have a pre-2.0 Examples solution to run in order to test against the first screenshot. Let me know if I can be of further assistance. Cheers, Miles

    Hi Andrew, After updating to 2.1.1 I'm afraid to report that this still looks like it's causing a problem. Is this snapping everything to the nearest pixel in SciChart a new policy since 2.0? If so, it could likely be the cause of my problems :) Cheers, Miles
