I have a requirement to write a real-time stripchart process in
DECwindows. However, since I am not familiar with DECwindows
programming with graphics, I am looking for some direction. The basic
functionality is:
Detached process that reads a configuration file for initial
parameters. It receives mailbox messages to add data to the
stripchart. As the data is added to the right, old data scrolls off
the left. (Conventional definition of a stripchart).
We are using Vaxlab software Library for most of the graphics, but the
real-time stripchart is not supported under DECwindows only under UIS.
What is the best way to approach this? I don't see direct support for
these type of graphics in DECwindows toolkit. It looks like I will have
to code this in the XToolkit. Is this correct?
Has anyone done this before? Are there any examples or code that may be
close that can give me a jump start? (Since this is for a fixed price
project, any saved time is a benefit.)
Thanks in advance,
Mark

If my memory serves, there is a stripchart widget posted in the ELKTRA::DW_EXAMPLES notes file. It is called the RGRA (rolling graph?) widget. If you can't find it, let me know - I still have a copy of the sources. It was written by Dominique Dierick. Should give you a starting point. -steve- | |||||

Check out the Athena strip chart widget. Source code is in the MIT X distribution. Porting it to DECwindows and VMS should not be too difficult. Ken | |||||

I'll look into RGRA example. Where can I get the code from the MIT X
distribution? I believe that all we have is what comes with basic
DECWindows.
Thanks,
Mark
