Ken,

YES - see the code below
(call back) for switching on/off graphics:

The following will set graph 0 to symbol 0 i.e. no symbol:

Thanks Ken!

I reduced the calls to SIMPLE_PLOT@ function as you mentioned.

Some time ago I had the numbers 1,2 for the graphs and at that time I tried something
to fix and forgot to change it back.

So, I changed it to 1 and 2 now, but the symptom remains.

You write that it could perhaps be:

Martin,

Thanks Ken (and John) for your clear explanation!

Now, I am afraid, I have no talent to read the manuals and understand the
manuals correctly.

So, I amended my code as you explained, Ken!

Nevertheless, it seems to me that there is still a problem with symbol 12 (and also with symbol 13). Although, after correction of my code, zooming in/out/to extents functions always correctly
(there is no change in the graphical symbol) and I see always symbol 12 or 13 after zooming. This time the problem
is moved to switching on/off the graphs. As soon as I switch off the grid and then I want to switch it on back, it never displays. I have to close the graphs first and then re-open them to see the grid.

So, I tried another graphical symbol (symbol 2, triangle) to test it. With this symbol (SYMBOL=2) EVERYTHING (any graphical function) works perfectly!

The only problem with SYMBOL=2 is that it is not quite suitable for me when
all points (87312 grid points+47041 border points) are displayed in their initial scale at once. I see only a blue filled rectangular area. Only when I start to zoom in,
I can clearly see particular points (as triangles) with all related data.

Since there is no dot (.) symbol for choosing as a point graphical symbol, for my purposes the plus sign (+) seems to be the best option (even symbol=13 is less suitable than 12).

Thanks again for your valuable advises!

Martin,

I think we need to see a small example that demonstrates the issue you have having.

The sample code below which includes zoom in/out, pan left/right/up/down and graph on/off (using symbol =12) does not exhibit the behaviour you are describing.

The problem appears to be with your coding, rather than an issue with how the library treats �symbol 12�.

Thanks Ken for your valuable help, thanks John for your useful remarks!

I know, I can have a small bug/error in my code which I am already unable to see. I will review it once again (today in the evening), although it already dreams me about the graphics and the code connected with the graphs.

But for general information I have to add the following:

Today, I tested ALL existing graphic symbols for points (symbols 1...13) with
my current code I have and tried ALL graphic functions with each symbol (1-13):

- zoom in,
- zoom out,
- zoom to extents,
- pan in +X direction,
- pan in -X direction,
- pan in +Y direction,
- pan in -Y direction,
- switch off the border, whereas the grid is switched on,
- switch off the grid whereas the border is switched on,
- switch off both graphs,
- switch on both graphs).

RESULT: symbols 1-11 have ABSOLUTELY NO problem and any above mentioned function performs excellent (don�t taking into account the suitability of graphics symbols,
I used them at their default size, but as John wrote, I can play with their size using set symbol_size function).

Symbols 12 and 13 performs problem free with all functions mentioned above EXCEPT the function switch off grid graph (switching on/off the border line is OK also with these symbols).
Simply, as soon as I switch of the grid (I see then only border line) and then I again switch on the grid back, the grid never displays and I have to close the graphs and re-open them again.

So, a magic must be there or so.

Martin,

I now understand the complexity of your function to set the symbols. You have four controls to control grid on/off and border on/off. You actually only need two. One for the grid ON/OFF and one for border ON/OFF.

Your analysis appears to indicate that there is indeed an issue with symbol 12 and 13. QUESTION Does the sample code I posted this morning via drop box work as expected when compiled on your machine? I wrote this last night to specifically try and replicate your problem.

Ken

[Martin_K]

Thanks Ken for your new code!

I tested it on my machine and have the following information for you:

Functions:

- zoom in
- zoom out
- zoom to extents
- pan pps X
- pan neg X
- pan pos Y
- pan neg Y
- new data

ALL work problem free!


As soon as I switch off the buttons (by unchecking their boxes):

- Idc
- Iac
- Linst

and then I switch them on again (by checking their boxes)

NO GRAPHS ARE DISPLAYED at all!

So - similar behaviour like with my two graphs (the difference is that in my case by switching on again the graph with SK border line, this line is displayed, only grid points in the grid graph are not displayed again).

It means, either I have a specific problem with my machine (I do not believe it, although I cannot exclude it fully or there is really a problem with symbol 12 (and also 13).

I switched on/off your graphs in all combinations, no one was again displayed after its switching off.

Works for me on both Windows 8.1 and 10.

At a loss to know what else you could try.

Perhaps some of the other users would be good enough to try the sample code from my post Wed Jun 24, 2020 8:21 am and report back their experience?

Ken,

below are videos taken from my machine:

1. Your graphs with Symbol 10
https://www.youtube.com/watch?v=TOj2D4AU_Uo

result: OK

2. Your graphs with Symbol 12
https://www.youtube.com/watch?v=qiJ9rfRrg2o

result: not OK

3. My graphs with Symbol 10, symbol size 2
https://www.youtube.com/watch?v=BIeTVSyGOQ8

result: OK

4. My graphs with Symbol 12, symbol size 2
https://www.youtube.com/watch?v=P4H0aTxEv34

result: not OK

This (symbol 12) on my graphs even caused that with combination of the
recording software when it was running, main window of my program
appeared for a while over the graphics window (as you can notice when watching the video), which should not. This was not the case with the symbol 10 on my graphs.

NOTE: When pressing my ZOOM TO EXTENTS (Cel� rozsah) button, it takes a few seconds to complete the task (since it deals with cloud of points (about 134 500 points)).

I will try both programs on different PC.

But at the moment, I will use SYMBOL=10 with SYMBOL_SIZE=2, since it
runs smoothly!

[Martin_K]

system information:

I have Windows 10 Pro, Version 1909, with all updates applied.

[Kenneth_Smith]

So for the example code:
Symbol 12 plus windows 10 plus latest DLLs and MOD files on my machine work.
But
Symbol 12 plus windows 10 don�t work on your machine. Are you 100% sure you have the latest/correct DLLs and MOD files on your machine?

[Martin_K]

Thanks for your tip Ken!

I found the problem!

I downloaded again the new DLLs + MOD, INS files from
your post of June 22, 10:35pm and compared the files
with the ones I used till now.

I found an older MOD file in the corresponding folder
when comparing to the MOD file from your download.

Now it works also with symbol 12!
