-
- 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.
