Steps to Reproduce

Go to link
See that the xAxis max value is multiple times the actual max value

It seems de-selecting series from the chart changes the xAxis max value.

Current Behavior

xAxis max value is 150 when it should be 25, the chart is unreadable:

When min and max on the xAxis are specified, only one series is shown at a time:

Expected Behavior

It stacks properly when x-axis type is category instead of value :

Hi @Ovilia , this is a simplified version of the example with just 2 series.

Same problems of xAxis max value is 50 when it should be 25; when min and max on the xAxis are specified (as 21 and 26), only one series is shown at a time; and it stacks properly only when x-axis type is category instead of value .

x-axis type is value :

x-axis type is category :

The default max value of the xAxis (when max is not set) seems to be weird.

I can also replicate this bug on my charts when I simply apply stack on my series when xAxis type is set to value

Here is our open issue: lightdash/lightdash#3076

Here is a modified stacked bar chart example

as you can see, the max value on xAxis should be 1320, not 3000

This only happens when xAxis type is value (not category)

I noticed that if you remove any of the series, the maxValue will be reduced as well, like maxValue is the maxValue * number of series whe stack is applied.

we're using

"echarts": "^5.3.0",
    "echarts-for-react": "^3.0.2",

It seams like stacked xAxis max value
example:

option = {
  xAxis: {
    type: 'value'
  },
  yAxis: {
    type: 'value'
  },
  series: [
    {
      data: [
        [10, 50],
        [15, 100]
        ],
      type: 'bar',
      stack: 'jrx'
    },
    {
      data: [
        [12, 50],
        [14, 100]
        ],
      type: 'bar',
      stack: 'jrx'
    }
  ]
};

And It's stack strategy like the line,but show the bar as it own way，without stacked and accurately.

Another question, the "value type xAxis" with "bar series" doesn‘t stack well

// Expected for value type x-axis with bar series stacked
const xStackMap = {};
option.series.forEach((series, index) => {

New Version！

support multi stack target
fix z-level error

const stackMap = {}
option.series.forEach((series, index) => {
  if (series.stack == null) {
    series.z = option.series.length
    return
  }
  series.z = option.series.length - index
  const xStackMap = stackMap[series.stack] || {}
  stackMap[series.stack] = xStackMap
  series.data.forEach((d, i) => {
