void GridAttributes::setAdjustBoundsToGrid ( bool  adjustLower,
bool  adjustUpper 
)

By default visible bounds of the data area are adjusted to match a main grid line.

If you set the respective adjust flag to false the bound will not start at a grid line's value but it will be the exact value of the data range set.

void GridAttributes::setGridGranularitySequence ( KDChartEnums::GranularitySequence  sequence)

Specify which granularity sequence is to be used to find a matching grid granularity.

Specifies the granularity sequence to be used for calculating the grid lines.

See details explained at KDChartEnums::GranularitySequence.

You might also want to use setAdjustBoundsToGrid for fine-tuning the start/end value.

See also
setAdjustBoundsToGrid, GranularitySequence

By default the GridAttributes class uses KDChartEnums::GranularitySequence_10_20.

Note
Granularity can be set for Linear axis calculation mode only, there is no way to specify a step width for Logarithmic axes.
The sequence specified by this method is ignored, if a fixed step width was specified via setStepWidth.
Parameters
sequenceone of the sequences declared in KDChartEnums::GranularitySequence.

void GridAttributes::setGridStepWidth ( qreal  stepWidth = 0.0)

Specifies the step width to be used for calculating the grid lines.

Note
Step with can be set for Linear axis calculation mode only, there is no way to specify a step width for Logarithmic axes.

By default the GridAttributes class does not use a fixed step width, but it uses KDChartEnums::GranularitySequence_10_20.

Parameters
stepWidththe step width to be used. If this parameter is omitted (or set to Zero, resp.) the automatic step width calculation will be done, using the granularity sequence specified. This is the default.

void GridAttributes::setGridSubStepWidth ( qreal  subStepWidth = 0.0)

Specifies the sub-step width to be used for calculating the grid sub-lines.

Parameters
subStepWidththe sub-step width to be used. If this parameter is omitted (or set to Zero, resp.) the automatic calculation will be done, using the granularity sequence specified. This is the default.

References d.

void GridAttributes::setLinesOnAnnotations ( bool  b)

When this is enabled, grid lines are drawn only where axis annotations are.

Otherwise annotations are disregarded as far as the grid is concerned.

The default is false.
