Steps to Reproduce

Current Behavior

option = { legend: {}, tooltip: { formatter: '@{product} @{2015} {c0}' }, dataset: { // 提供一份数据。 source: [ ['product', '2015', '2016', '2017'], ['Matcha Latte', 43.3, 85.8, 93.7], ['Milk Tea', 83.1, 73.4, 55.1], ['Milk Tea', 83.1, 73.4, 55.1], ['Cheese Cocoa', 86.4, 65.2, 82.5], ['Walnut Brownie', 72.4, 53.9, 39.1] ] }, // 声明一个 X 轴，类目轴（category）。默认情况下，类目轴对应到 dataset 第一列。 xAxis: { type: 'category' }, // 声明一个 Y 轴，数值轴。 yAxis: {}, // 声明多个 bar 系列，默认情况下，每个系列会自动对应到 dataset 的每一列。 series: [{ type: 'bar' }] };

Expected Behavior

1. tooltip字符串模版能够正常获取数据集的数据
2. dataset数据集解决这个重叠的bug

[Bug] The dataset data with the same name overlaps, and the tooltip formatter string template cannot access the dataset data

Steps to Reproduce

Current Behavior

option = { legend: {}, tooltip: { formatter: '@{product} @{2015} {c0}' }, dataset: { // Provide a copy of the data. source: [ ['product', '2015', '2016', '2017'], ['Matcha Latte', 43.3, 85.8, 93.7], ['Milk Tea', 83.1, 73.4, 55.1], ['Milk Tea', 83.1, 73.4, 55.1], ['Cheese Cocoa', 86.4, 65.2, 82.5], ['Walnut Brownie', 72.4, 53.9, 39.1] ] }, //Declare an X-axis, category axis. By default, the category axis corresponds to the first column of the dataset. xAxis: { type: 'category' }, // Declare a Y axis, a value axis. yAxis: {}, // Declare multiple bar series. By default, each series will automatically correspond to each column of the dataset. series: [{ type: 'bar' }] };

Expected Behavior

1. The tooltip string template can obtain the data of the data set normally.
2. The dataset solves this overlapping bug

tooltip.formatter templates are different from label.formatter Demo       📌 please close issue if problem solved.

I understand that the formatter of the tooltip is not supported, but what about the issue of data folding with the same name? Shouldn't there be two Milk Tea bars in the demo?

Shouldn't there be two Milk Tea bars in the demo?

yes, there are two bars in your code, but they overlap 100% since their data is identical. If you change the second 'Milk Tea' value from 83.1 to 44.4, you'll see two bar labels. Demo

Thank you for your answer, but I still think this is a bug. If the label is not displayed, I cannot correctly map the data because there is a missing bar.

one way of showing overlapping bars - Demo

Another way is to add data labels only for overlapping bars. See also #8125
