中，可以通过切换深色模式，直接看到采用主题的效果。</p>\n<p>ECharts5 除了一贯的默认主题外，还内置了<code>\'dark\'</code>主题。可以如下切换成深色模式：</p>\n<md-code-block lang="js" code="\'dmFyIGNoYXJ0ID0gZWNoYXJ0cy5pbml0KGRvbSwgJ2RhcmsnKTs\'" line-highlights="\'\'" />\n<p>其他的主题，没有内置在 ECharts 中，需要自己加载。这些主题可以在 <a href="https://echarts.apache.org/theme-builder.html">主题编辑器</a> 里访问到。也可以使用这个主题编辑器，自己编辑主题。下载下来的主题可以这样使用：</p>\n<p>如果主题保存为 JSON

href="https://echarts.apache.org/option.html#series-line.areaStyle">areaStyle</a>、<a href="https://echarts.apache.org/option.html#series-bar.label">label</a> 等等。这些的地方可以直接设置图形元素的颜色、线宽、点的大小、标签的文字、标签的样式等等。</p>\n<p>一般来说，ECharts 的各个系列和组件，都遵从这些命名习惯，虽然不同图表和组件中，<code>itemStyle</code>、<code>label</code> 等可能出现在不同的地方。</p>\n<p>在下面例子中我们给气泡图设置了阴影，渐变色等复杂的样式，你可以修改代码中的样式看修改后的效果：</p>\n<md-live lang="js"
