Usage

1. Add the Chart prefab to your scene
2. Update the minimum and maximum values of X and Y axis of the chart. These are used for clamping the values of the data points.
3. Clear the ChartData list of the Chart component prefab
4. Add the Chart component to your script
5. Add data points to the chart, one by one or in bulk
6. Manually call the render method of the chart if you want to render the chart after adding data points in bulk

Setting the minimum and maximum values of the X and Y axis of the chart is important. If you don't set these values, the chart will not render properly.

If you do not want to set them, you can set the recalculateMinMaxValues component value to true and the chart will automatically calculate the minimum and maximum values of the X and Y axis of the chart right before rendering.

public class ExampleScreen : MonoBehaviour
{
    public Chart exampleChart;

    void Start()
    {
        // Adding one data point and rendering the chart
        exampleChart.AddData(new Vector2(2021, 1));

        // Adding one data point without rendering the chart
        exampleChart.AddData(new Vector2(2022, 1), false);

        // Adding multiple data points without rendering the chart
        exampleChart.chartData.AddRange(
            new List<Vector2>
            {
                new(2023, 3),
                new(2024, 2),
                new(2025, 3),
                new(2026, 2)
            }
        );
        
        // Automatically recalculate the minimum and maximum values of the X and Y axis of the chart before rendering
        exampleChart.recalculateMinMaxValues = true;

        // Render the chart
        exampleChart.RenderChart();
    }
