Richard:
Haven't had time to dig in today. But try this, ideally in your
RBEditor:
(Based on the syntax for BeforeGenerate EEP in report:
RRBYW20:Quarterly_PieChart (shown here in Courier New font, casing in
just my style):
PLUGIN rCharts +
FILENAME midTerm.rbc +
|SAVE_TO_JPG midTermChart.jpg +
|IMAGE_WIDTH 324 +
|IMAGE_HEIGHT 244
SET VAR vImage = 'midTermChart.jpg'
RETURN
Alternately, use your line:
PLUGIN rCharts +
FILENAME D:\rbxData\midTerm.rbc +
...
Go from there if it works.
Best, Bruce

Subject [RBASE-L] - RCharts Plugin
I am attempting to use PLUGINs for the first time, with RChart being my
guinea pig.
I am still using RBase version X, and trying to decide if RCharts is
valuable to me before I upgrade.
I used the RChart desktop icon to launch RCharts and create a chart
file: MidTerm.RBC
My databases and this chart file are stored in folder D:\RBxData\
My goal is to insert the PLUGIN command into a form's EEP to initiate
the display of this chart in a separate window (either as a chart
within a separate form or otherwise).
But before doing so, I tried testing the PLUGIN command from the R>,
using the syntax from RCharts help file.
After navigating to D:\RBxData\ and connecting to the database
containing the table with the chart's data, I used this command at the
R>
R>PLUGIN RCharts vResults |FILENAME MidTerm.RBC
R>SHO vResults
-ERROR- Invalid parameter ( 639)
R>PLUGIN RCharts vResults |FILENAME D:\RBxData\MidTerm.RBC
R>SHO vResults
-ERROR- Invalid parameter ( 639)
I noticed that all example charts in the sample database bundled with
RBase are displayed within a report. This is done by inserting an
IMAGE object into the report, using the PLUGIN command to save the
chart to a file, and then retrieving this file into the report's Image
object. Does this also work for forms by placing an IMAGE object into
a form? Is it even possible to display charts within a form?
Based on the examples, and thinking my only option is to save the chart
to a file (rather than display it real time without a form), I tried to
create a .JPG file using the PLUGIN command:
R>PLUGIN RCharts vResults |FILENAME MidTerm.RBC |SAVE_TO_JPG
D:\RBxData\MidTerm.JPG
R>SHO vResults
-ERROR- Invalid parameter ( 639)
R>PLUGIN RCharts vResults |FILENAME D:\RBxData\MidTerm.RBC
|SAVE_TO_JPG D:\RBxData\MidTerm.JPG
R>SHO vResults
-ERROR- Invalid parameter ( 639)
My installed RBase files are stored on a separate drive partition F:\
as shown below. Although this shouldn't make a difference (hasn't so
far), I provide this info anyway.
F:\RBaseX (RBase is installed in this folder)
F:\RBaseX\RChartsX (RCharts is installed in this sub-folder)
F:\RBaseX\RDocsX (RDocs is installed in this sub-folder)
F:\RBaseX\...
F:\RBaseX\RChartX.RBM (This key RChart file is in the RBaseX folder
with
F:\RBaseX\RBGX.EXE the RBase software)
My experiments show I need help to get started using RCharts. I am
hoping that some of you RChart gurus can help me get going in using
RCharts within a RBase application.
