[Bug] Performance and Indicator Misplacement Issues in v10.0.0-alpha8

[M-Sufyan22]

Version

10.0.0-alpha8

Steps to Reproduce

Reproduction Steps:

• Set up a chart with indicators (built-in or custom)
• Load data using setDataLoader
• Update data via the callback function
• Observe indicator misplacement

Code Example:

chart.setDataLoader({
      getBars: ({
        type,
        timestamp,
        callback
      }) => {
        if (type === "init") {
          callback(chartData, true);
        } else if (type === "forward" && timestamp) {
          fetchMoreData(timestamp, callback);
        };
      }
    });

Current Behavior

Hi,
After upgrading from Klinecharts v9 to v10.0.0-alpha8, I've encountered performance issues, particularly with indicators. When new data is loaded via the callback, all indicators (both built-in and custom) become misplaced.

Expected Behavior

It should be very smooth while appending new data, and nothing should get misplaced.

Environment

- OS:
- Browser:
- Framework:

Any additional comments?

The indicator calculation has been changed to asynchronous, but it seems that there are indeed some problems now.

I tried a solution using the batch update mechanism, and it is working for me.
