### What problem does this feature solve? <img width="1260" height="863" alt="Image" src="https://github.com/user-attachments/assets/4acb07c9-56bb-4c9e-847e-231530b71a5e"; /> Hello: I want to achieve an effect like the one shown in Figure 1: 1. Display multiple ·yAxis· in a single group. 2. When the mouse moves, the marker lines remain consistent across each yAxis (correctly displaying the values corresponding to each indicator for the current date). 3. Be able to flexibly control which series are displayed in each yAxis This chart is implemented using Highcharts12, where the height of each yAxis is calculated as `plotHeight - (Vpadding * (item.length - 1)) / item.length`. The space between each yAxis is used to draw the legend. Here, I achieved this by drawing rectangles and text using `chart.render`. I would like to ask if ECharts can achieve such graphic effects? ### What does the proposed API look like? option = { xAxis: [ { id: 'xAxis-1' }, { id: 'xAxis-1' } ], yAxis: [ { id:'group1', type: 'multiple', items: [ { xAxisId: 'xAxis-1', top:0, height'45%', padding:'5%' }, { xAxisId: 'xAxis-1', top:'50%', height'45%', padding:'5%' }, { //... } ] } ], series: [ { xAxisId: 'xAxis-1', group: 'group1', data: [] }, { xAxisId: 'xAxis-1', group: 'group1', data: [] }, { xAxisId: 'xAxis-1', group: 'group2', data: [] } ] }; ----PS: This `options` is how I imagine it 😀. -- This is an automated message from the Apache Git Service.
