This example showcases creation of logarithmic axes, highlighting the functional differences between linear and logarithmic axes using line series.
Logarithmic Axis can be created by supplying type: 'logarithmic' argument when the Axis is created:
const chart = lightningChart().ChartXY({
// Specify default Y Axis as logarithmic (10).
defaultAxisY: {
type: 'logarithmic',
base: 10,
},
})
// Add second Y Axis that is also logarithmic (Math.E).
const axis = chart.addAxisY({
type: 'logarithmic',
base: 'e',
})If you notice an error in the example code, please open an issue on GitHub repository of the entire example.
