Question

ngx-charts-pie-chart angular5 library data structure

I am utilizing the ngx-charts library in my current project.

When using the onSelect method, I noticed that it only returns an object with attributes value and name, even though my list contains three attributes: value, name, and id.

Upon examining the source code, I discovered that the onClick method within the PieGridSeriesComponent only emits the value and name attributes.

PieGridSeriesComponent.prototype.onClick = function (data) {
        this.select.emit({
            name: this.data[0].data.name,
            value: this.data[0].data.value
        });
    };

Is there a way to modify the source files to change what onSelect method returns with the click event, or is there an alternate approach?

Answer №1

One interesting thing about Javascript is that it operates using prototypes, and this concept extends to TypeScript as well. This unique feature allows developers to freely override the prototype of onClick by defining their own function, without needing to make changes directly in the source code.

This implies that you can simply include the following code snippet within your own source code:

PieGridSeriesComponent.prototype.onClick = function (data) {
    this.select.emit({
        name: this.data[0].data.name,
        value: this.data[0].data.value,
        id: this.data[0].data.id
    });
};
