I've done everything like it was written.
Plz post the image of same axis to compare and see if there is anything worth of trying further

1) Pity i have not mentioned that i changed the demo code to make exactly the same font size as in my axis example, because small and larger fonts harder to compare. Plus when post make sure that posting does not scale the image file. But anyway, the differences in these two examples exist while in any my attempts i do not see any.

2) How specifically do you compile?
3) What Windows do you use. Mine is 8.1
4) Do i need to reboot after those manipulations with installation of hershey? Probably not (and i can not reboot, too much is open on the computer)
5) any changes in environment variables?
6) please remind what makes font bold, italic and underlined

UPDATE
OK, forget all the above, i found the error. I missed preceding line with the keyword [general] being confused by the words "So I created a simple.ini file with only the statement". So the file has actually two statements and my always busy, always in the hurry, tired brain, always translating for me foreign English language too literally-- so i took just one line and omitted the less important one!

(As a sidenote, that's called NLP, neuro-linguistic programming. Smile

All religions are based on NLP, specifically Christianity. After the Bible tells you on two-three pages hundreds of names "XXX lived 653 year and died. His son YYY lived 336 years and died. Son of his son ZZZ lived 890 years and died..." you are ready for further treatment and consumption and will believe in anything).

Indeed the exponent is larger, though of course the fonts look not good for all scalings, often terrible. Do you also see with font 1,2 the linewidth of plots also changes? But let's see if we find good looking font and good scaling. Yours above look not bad by the way

The only question left - please remind which option makes text bold and italic. Thanks

Thanks John,

That was another good hack! It now allows to run programs simultaneously. Multiple instances of same program are routinely running on my computer. Or just stay till i realize their results. It's like having multiple tabs in the browser.

And the advice of negative fonts was also good, i found the font which looks nice, but unfortunately it is italic. Italic layout hides pixelation of straight fonts.

Playing with Hershey rised the following obvious question:
do any antialised Hershey fonts exist in the nature? Why not, what's the problem? That would deliver high quality texts. There also exist a chance that on 4K monitors Hersheys will look without visible defects -- can anyone who has the latest tech try this source below on 4K monitors?

Here is the code for selection of best looking fonts/widths/charsets

Agustin,
Just noticed that this code has some bug i couldn't immediately fix - it crashes when resized with the error message "Invalid data value supplied to %pl". Usually %pl resizes with no problem which means i made a mistake somewhere

Just the information on what's to add to %pl in future: found the article in one journal which has all figures resembling Simpleplot style.

Dan, I do not know to what extend do you want %pl be improved.
I have not a great expertise in programming, but to me it appears that trying to make %pl a very powerful tool (with the same or similiar possibilities as Simpleplot) for making graphs would turn it into something difficult to code and at some stage difficult to understand (or follow).....I guess that using a list of calls to subroutines, each one producing some particular part of a graph, is still better, but perhaps I am wrong....probably Paul could enlighten us in this respect....

I would also say that at this stage, the use of Simpleplot under FTN95 is not straightforward as we have seen along all our discussions under this and some other topics....therefore, what I would expect, if Silverfrost considers that the inclusion of Simpleplot in the distribution is really a valuable tool, is that they:

a) include the installation of Simpleplot really as part of FTN95, i.e. the installation of Simple.ini and Hershey fonts along with the compiler.
b) include a help file for Simpleplot, as we already have for Clearwin, so that people could use it easily by accesing to the description and use of each subroutine.
c) improving Simpleplot with the help of David by updating what needs to be updated (real*8 variables?) and solving the problems with fonts (and symbols....the list of symbols in Simpleplot is not at the level of publications nowadays).
d) including the information and examples about how to use Simpleplot with Clearwin.

The main problem I see is that Silverfrost seems to be saying: "if you like, here is something called Simpleplot, but we have nothing to do with it and we will say nothing about it...", and consequently the lack of promotion to the users of FTN95 makes Simpleplot to rest in peace in the web site....until somebody starts to search for a Fortran library fro plotting graphs......and then you can go an buy something like GINOGRAF or use the free Simpleplot.....

just my thoughts,

Agustin

John,

You are right, the font -11 is as good as -12 in pixelation, i missed it taking some wrong sizes. Both though have the same defect: too small font for exponent

For color #RRGGBB you need latest DLL/LIB files from version 7.1

I edited the code, the button is used just to re-plot in case you need that. Spin wheel closes windows automatically. Or esc key

Differences in scaling between my and your images are probably due to screen pixel counts dimensions of our computers. I suspect all scales will change on future 4K monitors.

As to posting images, i use Postimage dot org, ask it do not rescale and take "Direct Link" it offers. I insert it in the text same way as you do adding two img tags (same will do the forum's own button "Img" above using Javascript, so make sure it is not switched off)

Of course it will take a lot of thinking and time to make Simpleplot perfect, to add many new options, select the best ones as a default etc but to change the obvious faults with the centering tics, add standard Windows fonts, 4-axis surface area, better scalability when the size goes to thumbnail dimensions, ability to run multiple %pl windows in the same screen, fix few tic mark/labeling defects, rebuild al to 24bit color paletttes for 3D plots in demo instead of 4 bit, all probably will not take too much time, most is already done, it just sometimes looks ugly, the Simpleplot was done 20 years ago and was not updated. To make me 99% satisfied not actually very much more is needed. D.Butland perfectly knows what is wrong with the look, feel and design of Simpleplot, even his school age kids made Android graphics software Bridplot which looks absolutely amazing, have you seen that?

The way you guys discovered when full Simpleplot helps %pl to expand its functionality should be primary design concept of future Simpleplot.

Thanks for more useful tips! I added margin change to the code so anyone can adjust the margin now or just play with it (and see it like everything in Simpleplot also has room for improvement and exposes some Simpleplot defects - in my case for example adding it messes with the font for exponent decreasing it even further, axis titles jump out etc. What units are used for margin adjustment? It is definitely not the % of plotting area which is needed for proper scaling of graph if resizing). I hope you guys will find new Simpleplot bug which messes with the exponent font but opposite way and return larger exponent font back Smile

And i found the crashing code bug when resizing - Simpleplot conflicts with %lw. Commenting this line makes it re-sizable fine but loses ability to auto-close the window

Simpleplot = huge_bugotron made in the era of unfamous FTN90, the champion of bugotrons. Needs some maintenance work ASAP

well, I was thinking about the code of Dan and see that with the %pl way he has some problems with the margins and captions and also with resizing the window.....well, what I like a lot of Simpleplot is the way it works with Clearwin (I have not found how DSLIN can work with Clearwin and I guess that the good interfacing between Simpleplot and Clearwin was probably the result of a close work between BUSS and Salford in the 90'...). So, as I prefer always a Simpleplot+Clearwin solution instead of a %pl window, I modified the Dan's code to obtain a similar result but in an easier way:

see next message with the code.....just another exercise...

I rewrote my program using %pl and simpleplot_redraw@.
It resizes OK. Thanks for one more trick - orientation.

aebolzan · Posted: Tue Sep 23, 2014 1:35 pm Post subject:

That's a nice solution, but there is one difference with mine: when you put L Margin = 1.5, I still have a correct graph and you obtain a graph where the Y-axis legend is moved to the right side of the axis (or is the axis that is moved to the left beyond the legend?......). I do not know why, but could it be another problem of %pl implementation?....but for the rest....the Simpleplot_redraw@ works fine and I like it.....
