What this software does
It allows the production of a range of charts
from data that can be entered and edited. The
program plots line graphs, stacked and grouped
barcharts and piegraphs. The current
implementation provides 2D display of the charts.
A number of options for obtaining various forms
of hard copy exist (saving as a !Draw file, or
printing via any standard RISC-OS printer driver).
__________________________________________________
Entering Data
Clicking SELECT on the iconbar icon will open an
empty edit window, into which the data may be
entered. This version allows a maximum of 30 data
sets, each comprising a label, and up to four
numeric fields.
Full scrolling and editing facilities are
available during data entry, by means of the arrow
keys. One useful key combination is
CTRL+SHIFT+COPY or CTRL+X, which will delete the
row of data at the cursor and close up the rest of
the data.
You can insert a blank row using
SHIFT+CTRL+INSERT, with the data from the current
line being all moved down one row. IF ALL THE ROWS
ALREADY HAVE DATA IN THEM, THE LAST ROW OF DATA
WILL BE LOST.
Function key F1 will try to turn on the help
system, either Acorn !Help, or !Bubblehelp.
Function key F3 will bring up the "save as"
dialogue box, except when a chart is displayed,
when the "save drawfile" box will be displayed
instead.
Function key "Print" will print the chart (if the
edit window has input focus).
Double clicking on a ChartDraw data file or
dragging a data file either into the edit window,
or to the iconbar icon will load the data,
overwriting any data that had previously been
entered.
Besides files in ChartDraw format, files of file
type text, data or CSV can be loaded by dragging
into the edit window or onto the iconbar icon. In
some cases, if the file does not start with the
standard chartdraw header, a query window will
open for confirmation before loading the file.
Data can also be passed in either direction
between the ChartDraw edit window and a !edit
window. Thus editing can be carried out using the
!edit application if preferred. Data can be
entered 'from scratch' using !edit, and then
transferred to the ChartDraw application (by
dragging a save icon to its edit window or its
iconbar icon), as long as the ChartDraw
application can recognise a valid data file.
As the chartdraw application will deal with files
of comma separated ASCII data it is possible to
set up other applications to produce data files of
the correct form.
************************************************
WARNING: All the editing is carried out on
strings of characters. These strings are converted
to numerical values only when the charts are
drawn. The application does not check these
strings for non-numerical content before it
converts using the VAL function. It is up to the
user to check the data entered for mis-typing etc.
************************************************

The Edit Window Menu
Clicking the 'menu' button in the edit window
brings up the following choices.
Delete column
Following the right arrow allows any complete
column of data to be deleted
Clear data
This will irretrievably clear the current data
prior to the entry of new data. Chartdraw asks for
confirmation before clearing the data.
Save file
Data files may be saved by dragging the save icon
to a directory viewer. If the full path name is
set up, then you can also click on the OK icon or
press <return> to save the data.
The function key F3 can be used as a short cut
for this option (unless the chart window is open,
when F3 will bring up the "save drawfile" dialogue
box).
It is also possible to drag the save icon to a
!Edit window, or to the !Edit icon on the iconbar.
The data is then transferred into !Edit.
Pie Charts
Line Graphs
Stacked Bars
Grouped Bars
These options cause the plotting of the chosen
type of chart. In the case of the piechart, a
sub-menu allows you to choose between plotting a
single large pie, or up to four small ones. Line
graphs and grouped bargraphs also allow a similar
choice of one or all of the data sets, but stacked
bargraphs always uses all the data sets.
