The latest update had more serious bugs:
1- When rotating the screen by 90 degrees, the wacom does not rotate. When I move my finger or pen horizontally Aacross the screen, the cursor moves vertically.
2- When I revert to normal after rotating left or right, the wacom does not comeback to the correct resolution. Wnen move my finger from top to bottom of screen, the cursor only moves fraction of the distance. Same thing when I move my finger from left to right of screen. The cursor arrives the right of the screen faster my finger. - Nov 05 2011
Thank you for the application again. It looks a lot better now. I still have the two issues I had before.

First, The CCW and CW are working opposite to what they should be. This happens whether I rotate my screen with krandrtray or xrandr. I fixed that by exchanging the CCW and CW in the xdeviceeventnotifier.cpp file.

Second, using the fixed CCW/CW version as above, when I rotate the screen with krandrtray, the screen dimension do not match the wacom dimensions.

I tried to change from absolute to relative and vise verse but it had no effect on the problems above.

Here is a new bug I found. I am trying to help improve this app as much as I can because it will be the most useful app for linux users with tablet notebooks.

Here is the scenario that shows the bug.
1- Rotate the screen ±90 using the xrandr program. The screen and tablet will rotate and works nicely.
2- Open the wacomtablet setting window and go to the pad or touch mapping tap.
3- try to change the "tablet area" mapping from, for example, "full tablet" to "force proportion".
4- The do actually change the area from the figures to the right by sliding the edges.
5- Now the tablet orientaion is reverted back to normal while the screen is still ±90 degrees. - Jun 25 2011
OK this sounds to be not a problem of your application but rather is a krandrtray problem.

When I rotated the tablet using the xrandr command from prompt as this:

xrandr --output LVDS1 --rotation left (right)

the wacom resolution was set right to accommodate the rotated dimensions.

Can you please confirm that this happens to you when rotating your screen with the kde utility krandrtray? - Jun 25 2011
Here are a couple of problems after fixing the reversed rotation above

1- It seems that when rotating right or left the tablet thinks the width of the screen is more than what it really is. Sliding the finger (or pen) to the right, moves the cursor farther than what is intended.

2- I also realized that after installing the wacomtablet, the panel is longer that the width of the screen when rotated. This behavior might be a result of the same bug leading to the above problem. - Jun 25 2011
I located where the changes must be made. I swapped cw and ccw functionality. However I ran into another problem which I discuss in a fresh reply. - Jun 25 2011
Let me say that this app is a must to be included in kde packages. The fact it detects screen rotation by krandrtray program makes it very useful. Here is one thing though.

I have a hp tm2t tablet. So I need the tablet to rotate with the screen. However, when I rotate the screen 90 to the left, the wacom rotates 90 degrees to the right (sliding my finger or pen to the right, moves the mouse to the left). This bug has no effect on 180 degrees rotation, since +180 is same as -180.
Where in the sourse file can I fix this, so I do not have to wait until next release?

Thank you again for this wonderful tool. Makes tablet useful with linux. - Jun 25 2011

OK I got it solved. The sip and/and PyQt version I grabbed from Fedora development tree was/were to blame. I tried to execute the line in qtiplot/qtiplot.pro manually and got a float exception. Then I grabbed the packages from kde-redhat repository and the qtiplot compiled fine and ran, althogh I did not have time to test it thoroughly. - Sep 13 2006
I installed the desired versions of sip and PyQT. And I changed the line which you refered to in your replies from
unix:system(sip -I /usr/share/sip -t Qt_3_3_0 -t WS_X11 -c $${MOC_DIR} src/qti.sip)

to

unix:system(/usr/bin/sip -I /usr/share/sip -t Qt_3_3_0 -t WS_X11 -c $${MOC_DIR} src/qti.sip)

and the error persists. There are more than one location in the line above. SIP executable, the /usr/share/sip. That is why I asked you to be more specific becase the change I made above did not fix it.

And since I have qt-3.3.6, could the problem originate from QT_3_3_0?

Thank you for the help in advance. - Sep 11 2006
can you please be more specific on what you mean by settibg the path to the correct SIP? thanx - Sep 10 2006
Is 0.8.7 strictly depending on PyQt 3.16? I have pyQt-3.15 and I get same compiling errors! - Sep 05 2006
sorry, my bad. It is a qtiplot patch link not qwt. - Aug 01 2006
The patches are created for the qtiplot tree. Does qtiplot preserve the structure of qwt? I will look at it and get back to you. - Aug 01 2006
OK, I have just added three symbols: Horizontal and vertical lines and star. They worked fine as of now. So I created a patch and now compiling. So I created a patch and created an rpm package for x86_64, Let me know if you are interested. - Aug 01 2006
maybe, you overlooked this post. Please let me know if you are interested. - Jul 31 2006
This application lacks some important symbols like the star and the horizontal line. the star is just a combination of the cross and diagonal cross. The line is even simpler.

If it is not of your priority to work on them, can you please direct me to which files I shall look in odrer to add them? - Jul 31 2006
README.html in the src tree. - Jul 31 2006
Hi
Thank you for this wonderful piece of software. I have just been able to build a 64 bit rpm for my FC5. I also build a liborigin rpm package as well. Please let me know if you like to add them to your library of binaries. I would love to donate them. - Jul 31 2006
oh I did not know they work. Thanks. - Apr 16 2006
thank you for the reply. As for the second suggestion think of latex way of controling typesetting. If you are writing a title, then you can specify different fonts/sizes for different words/letters within the title. qtiplot now only allows a global font and font size setting for each field. I will try to create a screenshot and post it here later. - Apr 16 2006
good piece of software indeed. I would like to see these two additions to the software which will be a very good plus:

1- Adding horizontal and vertival lines to the list of symbols like squares and diamonds.

2- allowing multiple fonts to be invoked into single entry; like in grace. - Apr 16 2006
thank you. I already added a couple of lines inside each of the .pro files to check for the cpu and suffix a 64 to the /use/lib entries and it worked.

It is a very promissing software and I will be always looking for improvements.

By the way, where to we report suggestions and improvements? Just by direct mailing to the author? - Mar 15 2006
thank you for the peace of software. I own a 64 bit machine and I can see that the installation directory for the qti+3party libraries are hard coded in the .pro files as lib. After the source compiles I had to link manually the qti modules from the /usr/lib to /usr/lib64 !

How can I make the qmake know about the correct library locations for the specific arch? - Mar 14 2006

Excellent application. I like it much better than kbibtex offered by the fedora extras. I managed to make a 64 bit rpm package if anyone in interested,

One small thing though, If I scroll using the arrow keys, the preview pane in the bottom of the window does not switch to the new selected reference. I have to click on it using the mouse in order to se the new selection in the preview.

But thanks again for the great application - Apr 10 2007
The file
tmp/kbib-0.5.2.3/usr/share/mimelnk/text/x-bibtex.desktop

conflicts with the file x-bibtex.desktop from kdelibs. Ofcourse if you are installing from source, the file from kdelibs will be replaced. My suggestion is to remove the creation of this file by the package since pretty much every linux installation with kde will have the kdelibs installted as well. - Sep 11 2006

The variables 'frame_rate' and 'frame_rate_base' are not used anywhere in the code. Safely comment on the two lines containg them and you will be good to go. - Nov 04 2006

great. At least this makes it usable assuming to tex support for the moment. With this feature fixed, LabPlot can really become my first choise of plotting.

Thank you very much. - Apr 10 2006
I have installed the new stable version l.5.1 and the problems I pointed earlier are still there. - Apr 06 2006
Picture is worth thousands of words. So I am posting this picture with emphasis to the problems I encountered with LabPlot 1.5.1.rc1

1- Position of ticks, data point and grid lines are not calculated accurately. For examples, draw these 7 points:
(0.001,0.001),
(0.01,0.01),
(0.1,0.1),
(1,1),
(10,10),
(100,100),
(1000,1000)
on a log10,log10 scale graph. Choose the symbol to be the Horizontal line (the one after the diamond) and make it as big as you can for clarity. Enable grid lines and you will see the symbol line does not match the grid lines except for the upper most and the lower most.

2- In the log scale, there is a problem in calculating the minor ticks' posistions. When choosing 2 minor ticks in the log10 scale, between 1 and 10 for example, they must be placed at 4 and 7 which is not the case. If you choose more than 8 minor ticks, then any tick after the 8th will be placed above 10 as you can see in the figure for the 9th and 10th minor ticks.

3- The minor grid line for the upper most minor tick is not drawn in the case of log scale.

4- When you enable tex label in the legend box and you have more than one data set, the legend label of the later comes on top of the legend label of the former.

Here is a screenshot that summerizes the problems.
