How to apply the custom labels in UWP Chart Logarithmic Axis?

This article explains how to customize the labels of a LogarithmicAxis in the UWP Chart control. By adding custom ChartAxisLabel objects to the CustomLabels collection, you can define specific labels and presentation of logarithmic data.

Step 1: Initialize the LogarithmicAxis and configure its relevant properties to define its scale and behavior.

LogarithmicAxis logarithmicAxis = new LogarithmicAxis();
logarithmicAxis.LogarithmicBase = 10;
logarithmicAxis.Interval = 1;
logarithmicAxis.Minimum = 1;
logarithmicAxis.Maximum = 100000;

Step 2: Create ChartAxisLabel instances for each custom label you want to display and them to the CustomLabels collection. Set the LabelContent to the desired text and calculate the Position based on the LogarithmicBase and the value for which the label is intended.

double logarithmicBase = logarithmicAxis.LogarithmicBase;

ChartAxisLabel hundred = new ChartAxisLabel();
hundred.Position = Math.Round(Math.Log(100, logarithmicBase), 3);
hundred.LabelContent = "Hundred";
logarithmicAxis.CustomLabels.Add(hundred);

ChartAxisLabel fiveHundred = new ChartAxisLabel();
fiveHundred.Position = Math.Round(Math.Log(500, logarithmicBase), 3);
fiveHundred.LabelContent = "Five Hundred";
logarithmicAxis.CustomLabels.Add(fiveHundred);

ChartAxisLabel thousand = new ChartAxisLabel();
thousand.Position = Math.Round(Math.Log(1000, logarithmicBase), 3);
thousand.LabelContent = "Thousand";
logarithmicAxis.CustomLabels.Add(thousand);

Output:
