This workaround was taken from https://stackoverflow.com/questions/77321155/customising-item-style-of-a-specific-item-of-the-series-using-dataset-property-i

Current Behavior

Currently the itemStyle is ignored if you are using a dataset.

Expected Behavior

Ideally itemStyle would not be ignored and I could use this same itemStyle across multiple series that use this datasource. There is a workaround, I want to confirm if that is the recommended approach or if this is indeed an issue?

This is not a problem with decal. Add aria: { decal: { show: true } } to your option

[brandonstubbs]

@Ovilia that does not solve the issue, as now there is a decal on each value. See example:
https://echarts.apache.org/examples/en/editor.html?c=bar-y-category-stack&code=PYBwLglsB2AEC8sDeAoWsCGAnCGBcysAJgKYDGGANgUrAM4AWwA7gWFgK4mwC-vANGmIYwGOiTA0h6OsA5YyJAgG1p6QtAwBbJbADkMEnv6wAblS4EAjALXpamnQT1hmwY2Yu6rJiGBJaAMpgAJ6UurSkFNSEdCFaAEbAMS44GNAA5uF6vLk8agC6QjyCMiQ4JHQqaqjq6qEgunogEEZq-ehFPADcQA

The decal should only be present with the data that has the name "two"

[Ovilia]

Dataset is used to seperate data from style, so it's natural that there is no dataset.source.itemStyle option. The correct way to set decal is like:
https://echarts.apache.org/examples/en/editor.html?c=bar-y-category-stack&code=PYBwLglsB2AEC8sDeAoWsCGAnCGBcya6sAJgKYDGGANgUrAM4AWwA7gWFgK5kA0plGgwIBtegwCeAWwBGwWrADkWSmEWwAvv3HS5CxRQhYK1Muo0BdTUS1ESGMBgZkwdIugbAuxsqPfF6aAwpXyUYM34ANxoeAgBGTV5_dEDg0MUwVmBFKJjQhI1_CxskjzIcMmFYEX9UYmIwCRB0kAgzf0L0Yo0AbiA

Ok thanks for confirming that is the correct approach to take

[brandonstubbs]

This does not work for the bar chart:

One bar should be triangle the other circle, they are both triangle
