Line Chart

Overview

Line Chart renders a series of numeric data points and connects them using lines. It supports custom styling through the Styler system.

At runtime or in the editor, the chart rebuilds itself whenever data changes or when the RectTransform size updates. All visible elements are generated dynamically.

Code Example

LineChartExample.cs

using UnityEngine;
using Evo.UI;

public class LineChartExample : MonoBehaviour
{
    public LineChart chart;

    void Start()
    {
        // Add data
        chart.AddDataPoint("January", 40);
        chart.AddDataPoint("February", 60);
        chart.AddDataPoint("March", 20);

        // Update existing point
        chart.SetDataPoint(1, "February", 75);

        // Replace point sprite
        chart.SetPointSprite(customSprite);

        // Change point size
        chart.SetPointSize(16);

        // Redraw chart
        chart.DrawChart();
    }
