## 图表类型：柱状图标签旋转 (Bar Label Rotation)

**生成指令**：你现在的任务是生成一个 ECharts 的 `option` 配置。请根据以下骨架代码和数据结构要求，结合用户的实际数据进行填充和修改，生成一份完整的图表配置参数。

### ECharts Option 骨架参考
请基于此结构（已剥离冗长写死的数据）生成配置。不要直接输出此骨架，而是要输出**包含真实数据和完整逻辑**的完整 `option` 对象：

```javascript
const posList = [ /* 请使用用户的真实数据数组替换此处 */ ];
app.configParameters = {
  rotate: {
    min: -90,
    max: 90
  },
  align: {
    options: {
      left: 'left',
      center: 'center',
      right: 'right'
    }
  },
  verticalAlign: {
    options: {
      top: 'top',
      middle: 'middle',
      bottom: 'bottom'
    }
  },
  position: {
    options: posList.reduce(function (map, pos) {
      map[pos] = pos;
      return map;
    }, {})
  },
  distance: {
    min: 0,
    max: 100
  }
};
app.config = {
  rotate: 90,
  align: 'left',
  verticalAlign: 'middle',
  position: 'insideBottom',
  distance: 15,
  onChange: function () {
    const labelOption = {
      rotate: app.config.rotate,
      align: app.config.align,
      verticalAlign: app.config.verticalAlign,
      position: app.config.position,
      distance: app.config.distance
    };
    myChart.setOption({
      series: [
