static final double DEFAULT_WIDTH

The default width.

Method Detail

setWidthPercent

void setWidthPercent(double percent)

Sets the width of the graphical representation of a data point along the x-axis. The size is specified as a percentage of the difference between the x-values of two consecutive data points. It is assumed that all the data points are evenly spaced along the x-axis, and that the resulting size is the same for all the data points.

Parameters:

percent - The new percentage. Valid values are between 0 and 100.

getWidthPercent

double getWidthPercent()

Returns the width of the graphical representation of a data point along the x-axis. The returned size is expressed as a percentage of the difference between the x-values of two consecutive data points.

setWidthPercent(double)

getWidth

double getWidth()

Returns the width of the graphical representation of a data point along the x-axis. The returned size is expressed in data space.

isUseCategorySpacingAtBorders

boolean isUseCategorySpacingAtBorders()

Returns true if the category spacing is used also at the left and right borders.

JViews 8.8

setUseCategorySpacingAtBorders

void setUseCategorySpacingAtBorders(boolean useCategorySpacingAtBorders)

Determines whether the category spacing is used also at the left and right borders. If set to true, category spacing is not only used between bars, but also beyond the leftmost and rightmost bars. If set to false (the default), this spacing is omitted. This setting matters only if getWidthPercent is less than 100.
