Currently we have overflow issue on the axis with fixed min/max. As described in the following issues.

• Bug with stack bar with min value #11086 Bug with stack bar with min value
• Incorrectly render lines overflow the chart. #9200 Incorrectly render lines overflow the chart
• Scatters are rendered outside of grid when setting axis range #10010 Scatters are rendered outside of grid when setting axis range
• Toolbox zoom returns chart in odd state #10224 Toolbox zoom returns chart in odd state

They are all related to the function of clipping the overflowed graphics.

So I'm planning to add a clip option in these series, whose default value is true.

The clipping strategy varies between series to achieve a good visual quality. For example:

• Scatter series will ignore the graphics whose centroid is outside the grid.
• Line series will use a rect clip path and let canvas do the clipping. But the symbol in line series will follow scatter series.
• Bar series will do an intersection operation with the grid rect.
• Custom series will also use a clip path to do the clipping. Since we can't sure what graphics will be used.

Series needs clip option

• scatter
• line
• bar
• pictorialBar
• lines
• candlestick
• custom

Q: Why not use clip path for all series?

A: Let canvas do clipping may cause visual artifacts on particular series. For example:

• It may cut the graphics into half.
• It may cause line along the edge looks thinner
