|
|
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 |
|
|

|
|
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 |
|
|

|
90 | 90 | - New: Added API for setting roundness of the corners for the background of the chart |

|
|
103 | 103 | - Fixed: Multi-line axis titles and labels now position correctly |
