Qt plotting - new strip?

markbeck

In IC6.1.5, there is a new method of plotting using 'strips'.  I found that the plot() command now supports specifying the strip number. 

This is great if you know the strip number, but what if I just want to add a new strip? 

How can I either create a new strip or have the plot command automatically create that new strip?

Thanks,
Mark

 

  • Hi Mark,

    There are some limitations in plotting in strip mode from OCEAN which are due to be fixed in IC615 ISR3.

    The stripNumber arg (or whatever it's called) has been supported for a while, but there's some problems with it in IC615 (I'd have to look them up, but I know I found some during testing just prior to release).

    Regards,

    Andrew

  •  Somewhat related to this, is there a way to query the QT plotter to determine how many strips there are in the current subwindow?

     If I could figure out how many strips there are in the current subwindow, I could just direct a function to plot the waveform to the next available strip number.

    Alternatively, I could use gensym() to generate an un-used number. This seems to work fine, but I don't know whether this creates any issues for the Qt plotter to have strips comming in using numbers that it hasn't encountered yet.

  • Mark,

    I'm not aware of one. There isn't in earlier releases either. You should file an enhancement request through customer support.

    gensym() is probably not the way to do this (for a start, it generates a symbol, not a number). What seems to happen is that the strip number is maintained - so if you plot several things to the same (high) strip number, they still go into the same strip.

    Regards,

    Andrew.

  • I submitted an SR: 42568138 (couldn't figure out how to specify that it was an enhancement request..)

    While gensym() does return a symbol, as long as the string you feed it is a number string, it will return a symbol that can easily be converted to an integer.  The nice thing about gensym, is that I'm guarenteed not to create the same strip number in a given plot.

     I noticed that the strip number did seem to be maintained, and I was able to create strips with numbers that were arbitrarily high (and not in order).  As far as I can figure out, it's just some sort of ID to the strip.  

    I did implement a "plot to strip" function using the gensym and it appers to be working.

    Thanks,
    Mark
