Exponential Trendlines

Configuration Features

This example demonstrates exponential trendline fitting using trendlineExponential:

• Exponential Growth: Shows data following 2^x pattern with solid red trendline
• Exponential Decay: Shows data following 100 * 0.5^x pattern with dashed teal trendline
• Logarithmic Scale: Y-axis uses logarithmic scaling for better visualization
• Custom Labels: Both trendlines include custom labels with equation parameters

Configuration Example

To use exponential trendlines, configure your dataset with trendlineExponential instead of trendlineLinear:

trendlineExponential: {
    colorMin: '#ff6b6b',
    colorMax: '#ff6b6b',
    width: 2,
    lineStyle: 'solid',
    label: {
        text: 'Exponential Trend',
        display: true,
        displayValue: true,
        color: '#ff6b6b',
        font: {
            size: 12,
            family: 'Arial',
        },
        offset: 10,
    },
}

Important Notes

• Exponential fitting works best with positive y-values
• The label shows the exponential parameters: a (coefficient) and b (growth rate)
• The equation is: y = a * e^(b*x)
• All styling options that work for linear trendlines also work for exponential
