A logarithmic axis is ideal for visualizing datasets with values that grow exponentially over time. It ensures that both small and large values remain readable by scaling evenly based on orders of magnitude. In the Syncfusion Blazor Toolkit, a logarithmic axis is configured by setting the ValueType of the primary Y‑axis to ValueType.Logarithmic. Additional properties such as minor ticks, grid lines, and formatting help improve clarity for analytical scenarios.

This sample demonstrates setting an explicit range on a logarithmic Y‑axis to focus on a specific growth interval. By defining the Minimum and Maximum values, lower‑order fluctuations are excluded, allowing the Chart to emphasize meaningful growth within a defined logarithmic scale. This approach is especially useful when analyzing product adoption, revenue growth, or performance metrics over time.

This sample demonstrates configuring a logarithmic axis using a custom base value instead of the default base‑10 scale. By setting the LogBase property on the primary Y‑axis, the Chart scales values using a different exponential factor. Custom log bases are useful when working with domain‑specific growth patterns, non‑decimal scaling, or scientific datasets that follow alternative progression models.

This sample demonstrates controlling the spacing of labels and grid lines on a logarithmic axis using the Interval property. By setting a higher interval value, the axis displays labels at larger logarithmic steps, reducing visual clutter when working with wide numeric ranges. This is useful for summarizing long‑term growth patterns and large‑scale performance data.
