Question

swap out a single amchart for a different one

Here's the current amchart I have:

https://i.sstatic.net/J8QLl.png

I'm looking to create another amchart with the same data. Essentially, I want to replace the existing graph.

You can find the new chart here ->

This is my Angular code:

prepareDataForTemplate(res) {
    // Your code logic goes here...
}

loadChart() {
    // Your code logic goes here...
}

The method loadChart() is where I need to update the graph...

In the amchart documentation ->

I'm having trouble understanding how to integrate the amchart code with my loadchart() method?

Answer №1

Although I'm still learning about amcharts, I'll attempt to provide some guidance.

Initially, it is assumed that you can save a reference to the chart you wish to replace. This reference could be defined as follows:

  private chart: am4charts.XYChart;

When creating your chart for the first time, you can follow this approach:

this.chart = am4core.createFromConfig(this.lineChartReturn, 'htmlIdReference', am4charts.XYChart);

If your implementation resembles the above structure, you can simply utilize the dispose function to remove the existing chart and then recreate it with the new data from lineChartReturn generated in the loadChart method.

loadChart() {
    if (this.chart) {
        this.chart.dispose();
    }

    // Your current logic to generate the new this.lineChartReturn

    // Re-create the chart using createFromConfig
    this.chart = am4core.createFromConfig(this.lineChartReturn, 'htmlIdReference', am4charts.XYChart);
}
