- Chart Window Menus
-
- Once a chart has been drawn, clicking on its
- window with the menu button will present a number
- of choices. Some of these are common to all
- charts, others are specific to a particular type
- of chart. All the actions are summarised below.
-
- Common choices
- Some actions are fairly clear. It is possible to
- replot the chart in an alternative form by
- choosing the new chart format. If pie charts, line
- graphs or grouped barcharts are chosen, then you
- may choose to plot one or all of the sets. The
- barcharts can be toggled between vertical and
- horizontal bars as the user wishes.
-
- Label
- Following this to the right allows four choices,
- viz. New label, Edit label, Display, Delete all.
- These options should be self explanatory.
-
- New label
- ---------
- You can add a maximum of TEN labels. When you
- choose "new label" from the graphic menu, a
- dialogue box will open. You can add the label text
- up to a maximum of one hundred characters. When
- the text is displayed on the chart it can be
- dragged anywhere in the graph window. If you
- double click on any label the dialogue box reopens
- for editing.
-
- Each label may have up to four font styles, and
- supports multi-level super and sub script.
-
- BORDER will toggle a border on/off around the text
-
- FILLED will toggle the solid background on/off
- (useful if the label overlays part of the chart)
-
- DELETE will delete that particular label.
-
- VERTICAL will toggle the label between normal and
- rotated 90°.
-
- Edit
- ----
- If no labels have been entered, then Edit
- will be greyed out, otherwise it will raise the
- same dialogue box. If instead of using the menu,
- you double click on the label on the chart, the
- dialogue box will open set up for that particular
- label ready for editing. If more than one label
- has been entered, then the arrow buttons at the
- top of the dbox will cycle through the labels.
-
- Display
- -------
- This will simply toggle the DISPLAY of labels on
- and off. It will not delete the labels.
-
- Delete all
- ----------
- This will clear all labels.
-
- Print chart
- Selecting this option will print the chart
- directly, using whichever printer driver is
- installed. The printed output should be the whole
- chart as displayed on the screen, but without any
- window borders etc.
-
- Make Drawfile
- This option will allow a copy of the chart to be
- output to disc as a draw file, which can
- subsequently be loaded into !Draw to allow
- additional annotation or various enhancements to
- be undertaken. The modified chart may then be
- printed from !Draw in the normal way.
-
- This option leads to a standard "save as"
- dialogue box, and the file may be saved in any of
- the normal RISC-OS ways, i.e. by dragging the icon
- to a directory display, or, if the full path name
- is set up, by simply clicking on OK or pressing
- <return>.
-
- Function key F3 is a short cut for this option.
-
- Line and Bar Charts only
- ========================
-
- Change Axes
- When a chart is first plotted the program selects
- automatically the range of the axes and the size
- of the index marks along the axis. For barcharts,
- it is assumed that the origin (zero) should be
- included in the graph, whereas the line graph is
- simply plotted over the range of values. The
- program chooses round numbers for the range and
- indexing along the axes (e.g. a full scale of 2000
- rather than 1922.5, with indexing at 400, rather
- than 384.5?). The change axes option allows the
- user to override to some extent the program
- choice, although the algorithm is not completely
- overriden, in that round numbers close to the user
- entered values may be chosen rather than the exact
- values entered! Piecharts always add up to 100%,
- so there is no need for any user choice.
-
- Piecharts Only
- ==============
- In the piechart menu, choosing segments allows
- all segments to be `exploded' or returned to
- normal.
-
- Note that to explode or return an individual
- segment, it is necessary to DOUBLE CLICK on the
- segment. If there is more than one piechart on
- screen, then the corresponding segment in each pie
- will be exploded or returned. More than one
- segment can be exploded by double clicking on a
- different segment each time. When clicking to mark
- a particular segment for canceling, click in the
- inner half of the segment to ensure the click is
- always registered.
-
- Bar Graphs Only
- ===============
- Vertical or Horizontal
- This action is self explanatory, the chart may be
- toggled between vertical and horizontal format
- bars.
