Setting Graph Background
to change the background color of the graphics
generated by Statit
Statit Custom QC
The default background color for Statit Custom
QC is lightgray for the graphics it generates.
If you want to change this color, you simply
need to specify the color you want the background
to be in the Options|Graphics menu pick, which
gives you the Statit Graphics Options dialog.
Statit Graphics Options
The Statit Graphics Options dialog lets you
specify many default characteristics for the
graphics generated by Statit. The characteristics
you want to specify are the Chart Background
Color and the Dataspace Background Color.
The Chart Background Color is the background
color of the area around the graph itself, that
is, the area where the title, axis labels, and
other text appears. The graph area itself is
called the Dataspace.
To remove the lightgray background, change
these backgrounds to Normal. This will make
the background appear white on most displays
and printers. This setting is saved for future
Statit sessions, so you need only do this once
on a given computer.
Specifying Backgrounds in Macros
When writing a macro, the command setgraph
is used to control the background colors. For
Using setgraph will change the background colors
for the current and all following sessions of
Statit. (These settings are stored in the Windows
Registry.) If you want to affect only a specific
graphic, use Custom Graphics or change the global
variables which control graph colors.
Global Color Variables
The following global temporary variables may
be set to control the colors of your graphics.
The colors specified on these variables are
used on graphics which are generated, but they
are not stored in the registry as when you use
setgraph. The following statements set the default
values of these variables.
%sg_chart_background = LightGray
let %sg_chart_border = Black
let %sg_data_background = LightGray
let %sg_data_border = Black
Using Custom Graphics
Custom Graphics commands give you complete
control over the appearance of a graph you are
generating. These commands are available by
interactively editing the graph in the Statit
Graph Window (using the arrow toolbar icon),
or by using commands in a macro or proc.
When you are creating a macro or proc, you
should first generate the graph you want, and
use the command "graph show" to display
the Custom Graphics commands which make up the
graph. Identify the base chart, which is probably
chart 1. Use the chart command to change the
background color of the graph. For example:
1 set ;
The color "Normal" is used in Statit
to define a color which usually means "no
color". That is, it is used on backgrounds
to ensure that no other chart components are
covered up or obscured by the background color.
Charts which overlay other charts use the color
"normal" which allows the lower charts
to show through.
In Statit e-QC, the default background colors
are set in the Statit e-QC Properties under
the Administration Folder. For individual macros
or for individual charts within a macro they
can be set in the macro itself.
%Orig_chart_background = %sg_chart_background
let %sg_chart_background= Cyan
let %orig_data_background = %sg_data_background
let %sg_data_background= Sand
Be sure to change the globals back or the backgrounds
will remain changed for any chart in the current
let %sg_data_background= %orig_data_background
The Custom Graphics commands given above work
