### 20.28 chart:interval-major

The `chart:interval-major` attribute specifies major intervals on an axis 11.9.

If the axis is linear and the value of this attribute is x with the value of `chart:major-origin` being w, major ticks are placed at *w* + *n* `*` *x* for *n* being any (positive, negative or zero) integer.

If the axis is logarithmic and the value of this attribute is x with the value of `chart:major-origin` being w, major ticks are placed at *w* * (10 ^{(n * x)}) for *n* being any (positive, negative or zero) integer.

Note: if x = log _{10} (*y*), then 10 ^{(n * x)} = y ^{n}.

This attribute is evaluated for a chart style that is applied to a `<chart:axis>` 11.9 element.

### 20.29 chart:interval-minor-divisor

The `chart:interval-minor-divisor` attribute specifies a divisor for the `chart:interval-major` 20.28 value, the division of which determines the minor interval.

If `chart:minor-logarithmic` attribute is `false` the ticks are placed as follows:

If *a* and *b* are the values of consecutive major ticks (see 20.28) and *m* is the value of `chart:interval-minor-divisor` then the minor ticks are placed at locations corresponding to the values *a* + (*b* - *a*) / *m* * *k* with *k* = 1,2, ... ,(*m* - 1). So the minor ticks are equally spaced before the logarithmic transformation.

If `chart:minor-logarithmic` attribute is true the ticks are placed as follows:

If *a* and *b* are the values of consecutive major ticks (see 20.28) and *m* is the value of `chart:interval-minor-divisor` then the minor ticks are placed at locations corresponding to the values *a* * ( (*b* / *a*) ^{(k / m)} ) with *k* = 1,2, ... ,(*m* - 1). So the minor ticks are equally spaced after the logarithmic transformation.

This attribute is evaluated for a chart style that is applied to a <chart:axis> 11.9 element.

### 20.37 chart:major-origin

The `chart:major-origin` attribute specifies the location of one major tick.

### 20.38 chart:minor-logarithmic

The `chart:minor-logarithmic` attribute specifies whether the minor ticks are spaced equally after the logarithmic transformation. If this value is false they are spaced equally before the transformation.
