Paul,

I too have been guessing the value when I�ve encountered the problem in cases where the limits are well defined.

The relationship:
Yminpl = Ymin_desired - (Ymax_desired - Ymin_desire ...

Paul, Thanks for the recent DLLs with updates.

Your suggestion of call winop@('%pl[y_min=-1.005]') got me thinking. The �obvious� value for y_min is -1, and where does the additional 0.005 come fr ...

Paul, one for you to look at time permitting.

Eddie, Perhaps I am lazy, but I find using %fn[Consolas] makes the alignment of text and controls much easier.

Paul,

Something that needs looking at when you have time. In the second %pl graph the options frame and scale=linear_log are used. The resulting plot is not correct. Please see my mark up here: ...

Here are some notes and very simple examples of using %pl

Where is does occur (not just at spikes, but sometimes at sharp edges), the al ...

In the following program two %pl graphs are used to plot identical data.

The data is an impulse function � zero everywhere but at one point where is it 10 units.

Does this help?

Paul,

No need for any changes. I understand what is happening now, and can explain the discrepancy between for example gFortran and FTN95 in this case, in somewhat more technical terms than simply ...

Thanks Bill, you comments are useful.

I tracked down the relevant part of the standard:

Thanks for looking at this Paul. I did wonder if I was pushing Clearwin+ beyond is intended capability.

The modified update2_cb in the code below, seems to work correctly, and I can easily incorpo ...

Paul,

A second one for you to look at.

I have been developing an application, which occasionally fails at run time when updating a number of graphics regions via %plmodule test
