value_ticks: A boolean that indicates whether the ticks on the value axis are visible or not. The default is false.
category_ticks: A boolean that indicates whether the ticks on the category axis are visible or not. The default is true.
position: A string that determines where on the axis to display the ticks. Valid values are outside, inside, and centered. The default is outside.
major_thickness: The thickness of major ticks. Major ticks are those that appear next to the axis labels. The default is 2 pixels.
major_color: The color of major ticks. This is a string holding triple hexadecimal values representing the red, green, and blue components of a color. The default is "000000" (black).
minor_thickness: The thickness of minor ticks. Minor ticks are those that appear between major ticks. The default is 1 pixel.
minor_color: The color of minor ticks. This is a string holding triple hexadecimal values representing the red, green, and blue components of a color. The default is "000000" (black).
minor_count: This applies to the value axis only. It sets the number of minor ticks between every 2 major ticks. The default is 4. The category axis displays minor ticks only in place of its skipped labels.

<!-- show centered ticks -->
<!-- show 3 minor ticks between every 2 major ticks -->
<!-- make minor ticks red -->
