GRAPH SETTINGS


GRAPH SETTINGS ( graphPicture ; xmin ; xmax ; ymin ; ymax ; xprop ; xgrid ; ygrid ; title {; title2 ; ... ; titleN} )

Parameter	Type	Description
graphPicture	Picture variable	Picture variable
xmin	Longint, Date, Time	Minimum x-axis value for proportional graph (line or scatter plot only)
xmax	Longint, Date, Time	Maximum x-axis value for proportional graph (line or scatter plot only)
ymin	Longint	Minimum y-axis value
ymax	Longint	Maximum y-axis value
xprop	Boolean	TRUE for proportional x-axis; FALSE for normal x-axis (line or scatter plot only)
xgrid	Boolean	TRUE for x-axis grid; FALSE for no x-axis grid (only if xprop is TRUE)
ygrid	Boolean	TRUE for y-axis grid; FALSE for no y-axis grid
title	String	Title(s) for graph legend(s)

Description

GRAPH SETTINGS changes the graph settings for graph displayed in a form. The graph must have already been defined using the GRAPH command. GRAPH SETTINGS has no effect on a pie chart. This command must be called in the same process as the form.

Note: You must not call this command if the graph was generated using the GRAPH command with the Object type graphSettings parameter. Refer to the description of the GRAPH command for more information.

The xmin, xmax, ymin, and ymax parameters all set the minimum and maximum values for their respective axes of the graph. If the value of any pair of these parameters is a null value (0, ?00:00:00?, or !00/00/00!, depending on the data type), the default graph values will be used. The xmin and xmax parameters are only taken into account for proportional graphs (xprop is True).

The xprop parameter turns on proportional plotting for line graphs (type 4) and scatter graphs (type 6). When TRUE, it will plot each point on the x-axis according to the point’s value, and then only if the values are numeric, time, or date.

Note: With the 4D Server 64-bit version for OS X, the xprop parameter is also taken into account for area graphs (type 5).

The xgrid and ygrid parameters display or hide grid lines. A grid for the x-axis will be displayed only when the plot is a proportional scatter or line graph.

The title parameter(s) labels the legend.
