All the text has the same font except that you can change the font for the title and keep the other fonts the same.

The general font is set using %fn before %pl.

To change the font for the title see item 406 in cwplus.enh...

Thanks for the info. I already changed the font for the title earlier. Maybe it could be worth to add these possibilities (changing the fonts/colours for the axis captions) in some next releases.

Again - thanks for your advises!

If you prevent %pl from drawing the axis labels via

%pl [x-axis=@,y-axis=@]

You can then add your title and axis captions using any font/size/colour by using the %gr routines within the %pl callback.

SELECT_FONT@, ROTATE_FONT@ and DRAW_CHARACTERS@

Defining the margins of the %pl region and GET_TEXT_SIZE@ helps with the positioning.

Paul, The new DLLs work fine for WIn32 - I can see that the bug with symbol 12 has been fixed.

But with x64 there seems to be a problem. This example fails.

It works OK for me. I what way does it fail?

Console opens, no Clearwin window created, no data printed to console, then terminates itself.

I plan to upload new DLLs within the next few days and hopefully this problem will prove to be resolved.

Fingers crossed Paul.

There's been a large number of intermediate releases (debugers, FTN, Plato etc) since the last official release and I am just wondering if I have perhaps missed something critical?

Ken,

I tried to change the font/colour/size of X/Y captions in the graphics. Couple of observations (better said problems) related to this:

1) First, I thought that I could call within %PL more than one call-back, so I defined a separate function in my module as follows (because I wanted that
any effect in changing font/colour/font size would relate to ONLY X/Y axis captions):

something went wrong with my latest post - here is the missing part:

.. which are wanted to be changed from the others which should remain unchanged.

Most important question is:
Is it not possible to call with %PL command contained in one integer function more than one call-back? I saw this as a way how to separate the influence
of changes in font/colour/size on X/Y captions from the others and if it is possible, where am I wrong?

As an assessment from a common user (occasional programmer) - by far - the easiest way would be to ADD new options for the %PL command such as:
[x_axis_font=], [x_axis_colour=], [x_axis_fontsize=] (the same for Y axis) and maybe a few more options along with good help (documentation).

So If you would have some ideas/comments/recommendations whick trick(s) could overcome current status of the %PL , I would be thankful.

Martin,

I am not surprised that your first attempt failed. The code it trying to produce two pl regions.

The function to draw the text should be called in the main pl call back within the if �plot adjust� logical test. Do this before you call COPY_GRAPHICS_REGION@ to copy the %pl to the �back up� internal graphics region.

After a call to rotate_font@(XX), it�s always a good idea to call rotate_font@(0.d0) immediately after you have completed the drawing operation with the text at an angle of XX.

Yes the characters in the yellow box will change. It�s drawn on the same graphics area as the %pl and prior to the call to draw the title text this would be at some default value probably defined by %fn before immediately before the %pl call � if I understand the user�s guide.

Generally I only use a single font and simply scale or rotate it where necessary.

You could open another window to display the internal %gr region. Then by adding a number of calls to SLEEP1@ at strategic points in the code, you can follow the progress of the various call back functions as they operate on each of the graphics areas.

Thanks Ken!

Now, I can zoom in/out/to extents as many times as I want and the X,Y captions retain always all their properties as I programmed it for them (picture below)!

I also incorporated switch on/off option for the bubble help (picture below)!

One question more (your answer will avoid my thinking in wrong direction):

I also have a raster image (.bmp) of the grid with SK borders which can
be seen under one menu option (there is also scale on the picture which corresponds to the reality).

I would also like to add a possibility in the menu option to zoom in/out/to extents using %SL (slider) in connection with mouse wheel. It means, as the wheel would spin, the raster picture would zoom in/out). Is this idea with the %SL command in connection with mouse wheel feasible or is there a more appropriate % command to use for such purpose?

Martin
