Problem to print values on the axis inside and outside WINDOW.
« on: February 20, 2021, 05:56:41 am »
Hi,
I have a problem and I don't find a solution.
Launching the code, press 1 or 2, and then any key at time.
In the ordinate is drawn a notch every X mc/s.

Given this notch, the target is to print the corresponding value on the axis. The problem is just to print it in the right position.
In the code below, we have to see the subroutine "grafici": lines 302 to 385, but the core of the problem is in lines 365 (inside the command WINDOW) and 374 (outside).

I have thought to print the value with che command _PRINTSTRING. At the moment there is no value, but the string "-". _PRINTSTRING, unfortunately, doesn't use the local coordinates of WINDOW (line 333), but always the general coordinates in pixels of the screen in use (line 331). So, in order to use _PRINTSTRING, the idea was to transform (line 365 and 374) the general coordinates of _PRINTSTRING, into the local coordinates of WINDOW by using fx! and fy!: lines 323-328.

But, as we can see launching the code, there is no way in order to have the strings "-" to fit and match the notches, also introducing a parameter k! (line 362) to do so. In any way, the strings "-" are ot of phase with the notches. The solution is not to use double precision variables for the transformation between coordinates.

So how we can print the values on the axis? I never thought that the problem was this!

Code: QB64: [Select]

Re: Problem to print values on the axis inside and outside WINDOW.
« Reply #1 on: February 20, 2021, 08:07:07 am »
I don't know if I understand this correctly, but if you have a positioning problem between screen absolute coordinates and WINDOW defined coordinates, I've used the map! function to good effect. If you have a value that needs translation from an old  range {minRange!/maxRange!}, it will translate that value to the new range {newMinRange!/newMaxRange!}. The order depends upon which way one is going, from WINDOW to screen or from screen to WINDOW. Hope this helps

Code: QB64: [Select]
  1. Function map! (value!, minRange!, maxRange!, newMinRange!, newMaxRange!)
  2.  
  3.     map! = ((value! - minRange!) / (maxRange! - minRange!)) * (newMaxRange! - newMinRange!) + newMinRange!

Aren't _PrintString coordinates automatically translated to Window coordinates like the graphics pset, line, circle..., if not, try same trick for translating Mouse Coordinates in a Window use PMap see Wiki.

Use Moses idea if printing outside the Window or returning screen back to normal.

BTW is your graph reversed? Both look flipped: up/down and left/right? Your screen bigger than my laptop, didn't see the axis arrows they were over in the storage shelf left of my laptop on my desk. :)

Hi and thanks for the tip, but it doesn't work with the damned _PRINTSTRING!

As you can see in the semplified code above (press any key to go ahead), outside WINDOW, your function works, because lines drawn in the WHILE cicle of lines 55 to 59, perfetly mach the notches drawn inside WINDOW in the WHILE circle of lines 40 to 44.

But, in the WHILE cicle of lines 62 to 66, no matches! I have also tried to add something like this:

_PRINTSTRING (55, H% - 1 - test!+K)

where K is an empirical and inexplicable value brutally added in order to have the match: no way.

Your screen bigger than my laptop, didn't see the axis arrows they were over in the storage shelf left of my laptop on my desk. :)

Ah TempodiBasic and or Kiara are recruiting ;-))

I have changed both of the 2 codes with 800x600.

In the second post, I have semplified the code, because the core of my problem is in the "graphs" subroutine of the first code I have posted. However, the program is finalized to calculate the maximum flow of a given drainage basin for a given return period, depending on the duration of the rain.

no, unfortunately they aren't...

You’re in SCREEN 0, where _PRINTSTRING is nothing more than a shortcut for LOCATE x, y: PRINT.

Here’s the relevant c-snippet for you:

Code: C++: [Select]
  1.        void sub__printstring(float x,float y,qbs* text,int32 i,int32 passed){
  2.             .... STUFF
  3.             if (im->text){
  4.                 int oldx = func_pos(0), oldy = func_csrlin();
  5.                 qbg_sub_locate(y, x, 0, 0, 0, 3);
  6.                 qbs_print(text, 0);
  7.                 qbg_sub_locate(oldy, oldx, 0, 0, 0, 3);
  8.                 goto printstring_exit;
  9.             }
  10.             ..... STUFF

If you’re in a text screen, simply use _PRINTSTRING as a LOCATE, PRINT, then restore the previous LOCATE position.

If _PRINTSTRING doesn’t work, just go back to LOCATE: PRINT

Edit: Nevermind...  I see your SCREEN statement down on line 70something...  You’re not trying anything in a text screen after all.

Re: Problem to print values on the axis inside and outside WINDOW.

SMcNeill,
yes, in fact I am in graphic mode.

It is not possible it is so complicated to put a text in a graph!:D

(I try to avoid the use of GOTO).

Found my old test code.

YES you MUST use PMAP for x, y conversion for both MOUSE and for _PRINTSTRING

bplus,
thank you very much! I did not have time yet to try PMAP after your message, but it was already my purpose to try it. I didn't know the command PMAP before today.

Thank's you bplus, with PMAP it works better!

But, as you can see in the code above on line 43, I have to add "-7" in order to have the strings "--" fitting. I don't know why! In line 41 PMAP gets the y screen coordinates of WINDOW y coordinates of the line drawn in line 39. So the string "--" printed with _PRINTSTRING in line 43 should match using y calculated by PMAP without this "-7"...

Code: QB64: [Select]
  1. CONST ore! = 6.723612
  2. CONST oreM! = 6.723612

Ok, solved!

PMAP works perfectly with _PRINTSTRING. In this case "--" didn't match the line because the line is drawn at the top and "--" in the middle (_--)-->up side down.
But this is not the solution without using PMAP, because in the preview tries the "--"  changed the distance with the line. So PMAP is necessary.

I find this interesting as I have not, thus far, investigated PMAP.

It would seem that it is essentially FUNCTION map! that I posted earlier, only optimized for screen ops, and much less typing.

You couldn't use it, like you can map!, for general computations, but it's much easier for graphics. You don't have to do that much range figuring.

Having learned about a new trick, I'll have to do some experiments now...;)

Yeah WINDOW is the way to go especially for math apps that you want standard 4 quads upper right #1 and going Counter-clockwise 2, 3, 4 with angle increases.

Anyway with that command (set correctly of course) angles Increase going counter-clockwise and y up is up and x up is right! The way you learned it in school before Basic ruined your mind by flipping it upside down and making angles increase clockwise ;-))

Trouble is I don't know if anyone uses it enough to report bugs when working with all the new extensions installed with QB64 ie how z axis might work with GL 3D?

I am a beginner, so I think that my level is not enough hight to report bugs, but maybe it wouldn't be bad if _PRINTSTRING worked also inside WINDOW. But perhaps there is a reason if it doesn't. For the 3D, maybe some games programmer. I don't think my graphics needs will go beyond 2D.
