Global Settings
RainPro lets you set the cycle of colours, line-styles, shading patterns, markers 3D effects and nib-weights used to draw each successive data series. These cycles should be set before you draw the first chart as they are used progressively by every chart you draw. If you have a set of similar charts in a trellis, the cycle will be reset to the beginning for each cell.
Setting styles for various chart elements
The ‘style’ property defines the appearance of many of the chart objects. For more details, see:
Style – summary of all style keywords
Barchart style – styles which apply to barcharts
Cloud style – styles which apply to cloud charts
Dial style – styles which apply to dialcharts
Frequency style – styles which apply to frequency plots
Stepchart style – styles which apply to stepcharts
Linegraph style – styles which apply to linegraphs
Polar style – styles which apply to polar charts
Pie style – styles which apply to piecharts
Response style – styles which apply to response surfaces
Scatter style – styles which apply to scatter plots
Table style – styles which apply to table charts
Trace style – styles which apply to trace charts
Min-Max style – styles which apply to min-max plots
Boxplot style – styles which apply to boxplots
Tower style – styles which apply to tower charts
Frame Style – applies to the chart frame
Trellis Style – applies to a trellis of small charts
Xstyle, Ystyle and Zstyle – to customise the chart axes
Hstyle and Kstyle – to set up the heading and keys
Lstyle and Cstyle – to set up the label and caption styles
Nstyle and Vstyle – for the notes and value tags
Fstyle – for the footnotes
Estyle – for equations used in a model-fit
Setting up headings, footers and captions
Heading – the main chart title, Subhead – secondary title
Footnote – footnote (at the bottom of the chart area)
Page labels – labels for any hidden dimensions (at the top left of the chart area)
Xcaption, Ycaption and Zcaption – titles for the axes
Values – value tags at each data point and VFormat to set the format of default numeric tags
Key – to add a legend for each data group and KeyFormat to set the format
Xlab,Ylab and Zlab – to over-ride the default axis labels
XFormat,YFormat and ZFormat – to set a format picture for the numbers and text
EquationFormat – to provide a template for the fitted equation
DateFormat,TimeFormat – to set a picture format for dates and times.
Locale – control the language used to format dates and times
Setting fonts, colours etc for these
In RainPro, you set the font for any of these objects in the same way with an expression such as: ch.Set 'hfont' 'ti,14,red'. You can define your own short-codes if you wish with ch.DefineFont.
To set the fonts for any of the above, see:
Heading, Subhead, Caption, Key, Notes, Labels, Values.
You can also set the appearance (Colour, line-style, nib-weight) of any of the following:
Axes, Datum lines, Pie sectors, Grid lines, Contours, Warning zones, Boxes.
Visual aids
Hints – to set hints on data-points
Tips – to set tips on data-points
Href – to set HTML jumps from data-points
