Fixed issues

• [Bug] Matrix component click event is not triggered even when silent is false #21389

Details

Before: What was the problem?

Even when matrix.body.silent was set to false (and the cell was made hit-testable, e.g., by setting itemStyle.color to 'transparent'), click events on matrix cells were not being emitted by the ECharts instance. This was because the underlying graphic elements (rects and texts) created in MatrixView lacked the necessary eventData (ECData) to identify them as part of the matrix component.

After: How does it behave after the fixing?

Click events are now correctly triggered when clicking on matrix cells. The event parameters include componentType: 'matrix', componentIndex, and the cell's name.

This is achieved by:

1. Importing getECData in src/component/matrix/MatrixView.ts.
2. Attaching eventData to the cell's text elements during creation in createMatrixCell.

Matrix is a layout so its text in the header or body should not trigger 'click' event by default. If you need this information, you need to add a new option matrix.triggerEvent (default false) like https://echarts.apache.org/en/option.html#yAxis.triggerEvent.

@Ovilia
Thank you for your review and the helpful feedback!

I've updated the implementation to add the triggerEvent option (default: false) following the same pattern as yAxis.triggerEvent.

I would appreciate it if you could take another look.

Please also add test cases in test/matrix.html.

It seems that events only trigger when there is text, correct me if I'm wrong. So what's the meaning of setting eventData of cellRect here?

@Ovilia
Sorry, you're right. I've removed the eventData from cellRect. Fixed in 1a12a50
