Bruce,
Thank you for your advise. What I learned in the meantime is that I can use
the PLUGIN command without specifying an image size. That wasn't the source of
my error message. The error message resulted instead from the commandR> SHO
vResultsMy problem was that the PLUGIN command does not create this variable,
so it didn't exist to be shown. I didn't know that to test with this variable,
you first need to define it as the error variable with the command.R> SET ERROR
VARIABLE vResultsAfter doing this, the error message went away and the value of
vResults was shown as 0.
Thanks for your help. Now that I have an initial R:Chart chart displayed in a
form, I can now experiment with the other option parameters to try to get to
the real capability I am trying to implement.
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

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.
