Current Behavior
When having a series with a time based x-axis, 'coord' mark points values are undefined. Using a type 'max' markPoint, the value is shown. Using a formatter with the 'coord' markPoint, {c} is shown as undefined.
Expected Behavior
The value of the 'coord' markPoint should be shown just like with the 'max' type markPoint

yes, value is not set for
format:'{c}'- it's a bug.workaround is to use
formatter: x => {return x.data.coord[1];}github-actions commentedon Oct 16, 2026

Still reproduces in ECharts v6.1.0 (2026-10-20, Chromium 151):
markPointdefined bycoord: ['2024-03-01', 198]withlabel.formatter: '{c}'.undefinedinstead of198.label.formatter: p => p.data.coord[1]renders198correctly.The
{c}template variable is not populated for coord-based markPoints on a time axis —params.valueisundefined;data.coord[1]is correctly set. Workaround: use the function form.Recording with timestamps: https://scenerecap.com/s/ixqgikw2h9
