DPlot

[raydela]

Hello,

Just recently downloaded your latest version (1.9.1 - registered) and began "poking" around as it's been a couple months since I've had a chance to use DPlot. Here's something I found in the Y=f(X,Y1,Y2...) dialog:

1.) The first time I entered the dialog (just to take a look) and hit <CANCEL> without modifying any entries, a warning message popped up indicating the "upper bound must be greater than the lower bound". If I hit <OK> then a warning message that I must enter a function -- In other words, I was stuck in the dialog simply by viewing it.

2.) I entered some simple function just to make the dialog "happy" (Y=X, from 0 to 1) and hit OK -- got a plot as expected.

3.) I went into the dialog again (the previous function was remembered --which is fine) and pressed <CANCEL>. Instead of simply exiting, the Y=X equation was plotted again.

4.) I went again into the dialog and cleared the function and the bounds and pressed <CANCEL>. This time the DPlot application exited altogether to Windows.

I checked the following other function dialogs and they seemed to work as expected when I pressed <CANCEL>:

X=f(T), Y=g(T)
Y=f(X),
Z=f(X,Y)

This is when I noticed that these other function dialogs had a default value for the upper and lower bounds, whereas Y=f(X,Y1,Y2...) opens the dialog with uninitialized (blank) fields for upper and lower bounds.

Ray,
Thanks for pointing out the glitch. This is fixed in a minor update: http://www.dplot.com/forums/viewtopic.php?t=43
