White lines are visible near rectangular items.

Hello. white lines are visible near rectangular items, how this issue can be solved?

Hello, could you post a picture of that and the code you are using?

[aregpetrosyan]

TreemapChart(
data = local,
evaluateItem = { it.percent },
treemapChartMeasurer = remember { SquarifiedMeasurer() },
modifier = modifier.fillMaxWidth(),
) { item ->
TreemapItem(item = item, onClick = onClick)
}

@aregpetrosyan If when you use the SliceAndDiceMeasurer the lines are no longer there, then this problem has to do with the algorithm for calculating node sizes. Can't offer a quick solution for this right now

[aregpetrosyan]

thanks for the answer, could you point to the part where squarified sizes are calculated, so we can have a look

[aregpetrosyan]

I checked, in the case of SliceAndDiceMeasurer the issue also occurs.

@aregpetrosyan It's here https://github.com/overpas/compose-treemap-chart/blob/master/treemap-core/src/main/kotlin/by/overpass/treemapchart/core/measure/squarified/SquarifiedMeasurer.kt

I think it's related to how your percent variable is calculated, though. You might lose some precision there. I've modified the sample a bit and managed to reproduce similar lines with incorrect values (the background is white and all nodes' backgrounds are red):

Thanks for the answer, will have a look

Are there percent values which would prevent these white values?
