Why are there no ticks?

Why are there no ticks? - briefly

Ticks are absent because the habitat does not provide the necessary humidity, temperature, and suitable hosts required for their life cycle, making survival and reproduction impossible.

Why are there no ticks? - in detail

The absence of tick marks on a plot usually results from one or more of the following conditions.

• Axis limits are set so narrowly that the automatic tick generator finds no suitable intervals. When the data range is extremely small, the default algorithm may suppress ticks to avoid overlapping labels.
• A logarithmic scale is applied to an axis that contains values less than or equal to zero. Logarithmic tick generators cannot place marks on non‑positive numbers, so they may hide all ticks.
• Custom tick locators or formatters are defined without providing explicit positions. If a user supplies a formatter but omits a locator, the axis has no locations to label.
• Tick visibility flags are turned off in the rendering configuration. Many libraries expose properties such as showticks=False or tick_params(labelsize=0), which hide both major and minor ticks.
• The figure size or resolution is too low for the library to render ticks legibly. In such cases the rendering engine may drop ticks to preserve visual clarity.
• Conflicting style sheets or theme settings override default tick behavior. A theme that disables ticks for a minimalist appearance will suppress them globally unless overridden locally.

To resolve the issue, verify each of these factors:

1. Check the axis limits and expand them if necessary.
2. Ensure the data range is compatible with the chosen scale (linear vs. logarithmic).
3. Define both a locator and a formatter when customizing ticks.
4. Review visibility settings in the plotting API and set them to True or appropriate values.
5. Adjust figure dimensions or DPI to give enough space for tick rendering.
6. Inspect any applied style sheets and modify or remove directives that hide ticks.

Applying these diagnostics systematically restores tick marks and improves interpretability of the visual output.
