|
|
25 | 25 | ======== |
|
|
26 | 26 | Please note that if you have already installed a previous version of |
|
|
27 | 27 | QtCommercial Charts, you should first uninstall it with |
|
|
28 | 28 | make uninstall |
|
|
29 | 29 | |
|
|
30 | 30 | Configure project with qmake and build project with make: |
|
|
31 | 31 | (Linux) make |
|
|
32 | 32 | (Windows with MinGw) mingw32-make |
|
|
33 | 33 | (Visual Studio) nmake |
|
|
34 | 34 | (OSX) make |
|
|
35 | 35 | |
|
|
36 | 36 | For debug builds: |
|
|
37 | 37 | qmake CONFIG+=debug; make |
|
|
38 | 38 | or |
|
|
39 | 39 | qmake CONFIG+=debug_and_release; make debug |
|
|
40 | 40 | |
|
|
41 | 41 | For release builds: |
|
|
42 | 42 | qmake CONFIG+=release ; make |
|
|
43 | 43 | or |
|
|
44 | 44 | qmake CONFIG+=debug_and_release; make release |
|
|
45 | 45 | |
|
|
46 | 46 | For both builds |
|
|
47 | 47 | qmake CONFIG+="debug_and_release build_all"; make |
|
|
48 | 48 | |
|
|
49 | 49 | If you want to install the libraries to your Qt library directory use: |
|
|
50 | 50 | make install |
|
|
51 | 51 | |
|
|
52 | 52 | If you want to uninstall the libraries |
|
|
53 | 53 | make uninstall |
|
|
54 | 54 | |
|
|
55 | 55 | Building as a statically linked library |
|
|
56 | 56 | ======================================= |
|
|
57 | 57 | |
|
|
58 | 58 | The same as above applies you will just have to add staticlib to the CONFIG: |
|
|
59 | 59 | qmake CONFIG+=staticlib |
|
|
60 | 60 | |
|
|
61 | 61 | Documentation |
|
|
62 | 62 | ============= |
|
|
63 | 63 | Documentation can be found from doc/html directory. The documentation |
|
|
64 | 64 | can also be generated with: |
|
|
65 | 65 | make docs |

|
|
95 | 102 | Known Issues |
|
|
96 | 103 | ============ |
|
|
97 | 104 | - Automatic scaling of the axes is only done when you add a series on a chart |
|
|
98 | 105 | - If adding several axes, automatic scaling is done based on the last axis added |
|
|
99 | 106 | - Only one Y and X axis can be visible at the same time |
|
|
100 | 107 | - Unit label for axes is not implemented |
|
|
101 | 108 | - Switching off OpenGL (after using a QGLWidget as a viewport) causes a crash in OSX |
|
|
102 | 109 | - Setting minimum margins breaks down the layout in some cases |
|
|
103 | 110 | - DateTimeAxis is not supported on ARM because of floating point precision |
|
|
104 | 111 | issues (qreals are floats) |
|
|
112 | - Declarative plugin is available from Qt 4.7.4 onwards because of missing | |
