Richard:
There may be a path here. The R:Charts Plugin Syntax guide reports: "The
following PLUGIN syntax is available to create an image of a chart,
based upon an existing chart file" (emphasis mine).
So, if you've already developed the chart template for your dynamic
series - where each chart ultimately generated contains the same three
charting objects - each just waiting on the dynamically provided data,
then maybe this sample will help; 'coz the parameter hooks for the three
series are already in the .RBC file:
Give this a shot in your PLUGIN setup (stripped down for simplicity):
----------------------------------plugin vars .......
SET VAR vrbc_result TEXT = NULL
SET VAR vrbc_chartTile TEXT = 'richards_rack.rbc'
SET VAR vrbc_seriesTitle_0 TEXT = 'Liesure'
SET VAR vrbc_seriesTitle_1 TEXT = 'Sport'
SET VAR vrbc_seriesTitle_2 TEXT = 'Dress'
------------------------------------do the do .......
PLUGIN RCharts v11_result +
FILENAME .vrbc_chartTitle +
|SERIES_TITLE[0] .vrbc_seriesTitle_0 +
|SERIES_TABLE[0] line_leisure_t +
|SERIES_XLABELS[0] fiscal year +
|SERIES_XVALUES[0] fyearNo +
|SERIES YVALUES[0] totalSales +
|SERIES COLORS[0] pointColor +
... +
|SERIES_TITLE[2] .vrbc_seriesTitle_2 +
|SERIES_TABLE[2] line_dress_t +
|SERIES_XLABELS[2] fiscal year +
|SERIES_XVALUES[2] fyearNo +
|SERIES YVALUES[2] totalSales +
|SERIES COLORS[2] pointColor +
...
Of course, all the other parameters could be variablized to suit your
taste. The chart Legend will display your series' names.
Your question came at a great time. I was just about to bite the bullet
on dynamically-defined charting, and this pushed me forward.
Thank you. Ask anytime, Bruce

Subject [RBASE-L] - Setting R:Chart legends
I have been playing with R:Charts on and off for several years trying
to create dynamic charts that are useful to me. Hopefully there is
someone who can help me solve my problem with modifying a chart's
Legend. My problem is easily demonstrated using images from the
R:Chart user guide. I am using R:Chart version 10.5.
An example chart from the user guide is:
Inline image
The legend values for a line chart default to Series1 and Series2 when
a line chart is created. I can make the above chart and I do get the
resulting default legend values (Series1, Series2).
Another example chart from the user guide is:
Inline image
The legend values have been changed from Series1, Series2 and Series3
to meaningful values of Leisure, Sport, and Dress. I have attempted
to poke at every option in R:Charts, but have been unable to figure out
how to make the change to the legend labels to get user defined values
like Leisure, Sport and Dress for a Line Chart. And I didn’t see
anything in the Plugin syntax about naming labels, which is what I
really need.
Is there a R:Chart guru who has mastered how to do this? I would
love to learn how!
Richard
