Steps to reproduce

See the link above.

What is expected?

The data in chart is correct.

What is actually happening?

The data of "公司业务系统" in bar chart is wrong. For example, in row three, the data of "公司业务系统" should be 1332.5333333333333. But it is 1666775.3333333333, as same as "ECM".

Do you mind creating a minimum demo for this? To move the unnecessary parts and provide a demo with minimum series and minimum data.

@Ovilia
Due to the maintains, I can't create a demo on gallery. Here is a minimum option.

option = {
    "dataset": {
        "source": [{
                "timestamp": 1568191020000,
                "ECM": 26311.466666666667,
            },
            {
                "timestamp": 1568191140000,
                "ECM": 1666775.3333333333,
                "GSWY": 1332.5333333333333,
            },
        ]
    },
    "xAxis": {
        "type": "time",
        "axisLabel": {
            "interval": 0
        }
    },
    "yAxis": {
        "type": "value",
    },
    "series": [{
            "type": "bar",
            "name": "ECM",
            "encode": {
                "x": "timestamp",
                "y": "ECM"
            },
            "stack": "one",
            "itemStyle": {
                "normal": {
                    "color": "#2ec7c9"
                }
            }
        },
        {
            "type": "bar",
            "name": "GSWY",
            "encode": {
                "x": "timestamp",
                "y": "GSWY"
            },
            "stack": "one",
            "itemStyle": {
                "normal": {
                    "color": "#97b552"
                }
            }
        }
    ],
    "tooltip": {}
}

I think there is a missing entry of "GSWY" in the first item of the dataset. Is this a mistake?
But ECharts should handle this kind of input and this could be treated as a bug.
