In the HeatMap chart, each cell can draw color according to the value…
But after the cell drawing, the HeatMap’s Gridline is covered by the cell color (see the jpg file before and after)

Can I always make the gridline front to the top of cell color? (I Want to see the major grid line after cell drawing…)

Hi there,

Unfortunately, it isn’t possible to draw series beneath the grid for now. However, you can make the FastHeatMapRenderableSeries semi-transparent, so the grid lines will be visible, or place several VerticalLineAnnotations above the chart at specific coordinates. You can learn more about annotations in this article:

Hope this helps!

Best regards,
