Before this commit, we tried to hide some labels depending of the available size of the graph. However, it doesn't worked when the graph is updated. A much simpler solution is to use the scale’s automatic tick generator implemented in D3. So, in this commit, we realized that 'tickValues' is unnecessary because data are passed correctly (see 'svg.datum(data);') and labels are defined in 'ticksLabels'. There is nothing else to do. We had to remove the skipped test because 'renderEnd' is not triggered for line chart. We need to update nv.d3. We already tried to fix this issue in the following commit: https://github.com/odoo-dev/odoo/commit/c4937132a38873761fa0ac0b41c983b917cb52f1 Documentation: https://github.com/d3/d3-axis#axis_tickValues closes odoo/odoo#27828
