Did you try the obvious ``` dataZoom: {inside: {type: 'inside'}}``` ? Without Minimal Reproduction code it is hard to debug...

yep, @plainheart is one step ahead, while I was typing :-) the right code ...and to zoom for the **edges** add ```lineStyle: { width: 2.5 * currentZoom }```

agree, would be better if _heatmap.markArea_ display is consistent with _bar.markArea_.

If you have lots of data, use _codepen.io_ to present a working Minimal Reproduction. _brushselected_ works fine with large selections - [Demo](https://echarts.apache.org/examples/en/editor.html?code=MYewdgzgLgBBIFcBOwCmMC8MDaBdA3AFABmISMAFADaqwCWGADPjHQDwCMj3zdA1HwCUMAN6EYMGrAAemGAFkAhlAAWAOiSKwAExABbCoKISpMAJ5ylqjVt0Gj4uIhSo1ABwQQVFbNIA0ZrhGMAD0ISLSAFww_ubRZgC-goQJhNqoVIoWWByhIRCowIQgblB04HJiEmVQNNEiMFCo0lDRAOQAIsqKMACCeohgrTBtMHxOyGhqNGAA5qowCX6O2t0Fww3wk-hLjlp0esrlYNHEilQFyxIARkieKvWO1SAgVNcgUThtSIVQbbhXCSNFRIEBQWqoAAqZjcqHa6XeCDAaDagIkYVUoPBNGhsPaxDo0gASspUKinsCsRCOhkstF0pkLAAqGBcbiOXYSaS9aR0CD1TnmHl8gWAgpIOiofk4ClVIHVGFwkYQYDKJpIVEwUBUMgAITMkTaqyginJ8okEDMeneVAAynQAF5KgCsfhgFPRIUkiiQszhUDu6DCMGuCFmbt0Qxgim02jdBXQAGIOABOAAczoA7BTBbgUkQ9GYAMIqH1QNTgChtW73Ao0YBNbSaihuYQYAB8okcdbkbjU12UwBU2EYuBgAH4YH2B1AhyPcGo679UNp52pjYoAJI6ZowdptYwwQslsuL2gAeVKxwoDRqdTl1WarTaUEVhr4JTK4H7dy8akxYIQriqB8KMEgMnSbR8BBZigXAhRmkCEAINcTQtO0S4NiuIx8HW0yoHMqipBISREEkQA)

good idea for a new [Feature]. Currently [symbol](https://echarts.apache.org/en/option.html#series-line.symbol) is attribute of the entire line and cannot be changed for individual items.

Simple hierarchies could be built with [trees](https://echarts.apache.org/en/option.html#series-tree). After customizing, one could get something [like this](https://helgasoft.github.io/echarty/articles/img/tree.custom.mp4). For more elaborate org charts, you'll need a specialized JS library.

maybe [graphs](https://echarts.apache.org/examples/en/editor.html?c=graph-grid) would be a better choice than trees.
