How to Set Current Zoom Value to Specific Value in JavaScript Diagram?

You can set current zoom value to specific value by calculating the required zoom factor.
The zoom factor determines how much the diagram should be zoomed in or out. It can be calculated by dividing the specific value by the current zoom value of the diagram.
You can use the zoomTo() method to apply the zoom. This method adjusts the zoom level of the diagram based on the calculated zoom factor, effectively zooming the diagram to the desired value.

The below code snippet demonstrating how to set the current zoom value to a specific value:

document.getElementById('zoom').onclick = () => {
 let zoomOption = {};
 //You can set any specific value as the target
 let target = 0.3143011474609375
 zoomOption.zoomFactor = target / diagram.scrollSettings.currentZoom - 1;
 diagram.zoomTo(zoomOption );
 console.log(diagram.scrollSettings.currentZoom)
 diagram.dataBind();
};
