Graph window menus
Whenever a graph is being displayed, clicking
'menu' will lead to a further range of options.
Plot type
This option leads to a submenu allowing the data
to be plotted normally, or with either the x-axis,
the y-axis or both x- and y- axes on a logarithmic
scale. For speed, simply clicking on the Plot
type option itself will produce a normal plot. The
program traps (I hope) attempts to take the log of
zero or a negative number.
Graph legend...
This opens a window which allows you to enter
text to label the graph axes, and a title string
for the graph. Clicking on display will place the
labels on the graph, while delete will remove
labels from the graph (the text remains in memory
and can be reinstated by reselecting label and
clicking on display). Simply closing the menu will
leave the state of the labels as they were. This
current version allows you to use up to four font
styles, and also super and sub scripts by clicking
on the appropriate icons.
The labels are dragable and can thus be dragged
to anywhere on the graph if you do not like the
default positions. The same labels will appear on
any graph, with the previous position being
remembered. The y-axis label is plotted
horizontally or plotted vertically, rotated by 90
degree.
If the labels are displayed, then double clicking
on one of them will open the dialogue box ready to
edit the labels.
Graph layout...
This leads to a submenu with two choices, axes
and points.
Axes leads to a dialogue window in which various
aspects of the way the graph is laid out may be
changed, e.g. whether the axis pips are inside,
outside or straddle the axis lines, the size of
the pips, whether the graph is boxed in. The
choices available are under continuous review, and
may be changed in future releases.
Points leads to a further submenu which allows
the size of the symbols on the graph to be
changed, and the type of symbol (shape and whether
filled or outline) used to plot each set of data
to be independently chosen. Note that the size of
the symbols is set in os units.
Caption
This leads to a submenu, which opens a dialogue
to enter captions for the point sets and the
lines. It is very similar inoperation to the graph
labels. The captions are displayed below the
graph.
Save drawfile
A standard 'save as' dialogue box will be opened.
The file icon may be dragged to a directory
viewer, or if the full filename path is set up it
is possible to click on OK. The file saved is a
Drawfile of the graph being displayed. It is also
permissible to drag the file icon into a !draw
window to add the graph to an existing draw
document, or drag the icon to the !draw icon on
the iconbar, when a new draw window will be
opened. The production of !Draw format files means
that the graphs can be loaded into !Draw or
!DrawPlus for enhancement, and can also be loaded
into the various DTP packages now available.
Note that memory for use as a buffer is taken
from the free wimp pool, and then released again
when the drawfile has been saved. If there is not
enough available memory, a non-fatal error will be
generated, and the operation aborted. If this
happens, then quit any non- essential applications
to free some memory and try again.
Print Graph
This leads to a dialogue to printout the complete
graph via whichever RISC-OS printer driver
application is installed. A printer driver must be
installed, otherwise !MultiPlot will complain.
