# qplotmarker
**QPlotMarker** – an interactive marker for **QChart** (Qt). Supports color and orientation (vertical/horizontal) changes, snaps to data points, and displays intersection coordinates.
# Install
You must have installed [project dependencies](https://github.com/Mark194/qplotmarker#dependencies)
1. Clone repository
```git clone https://github.com/Mark194/qplotmarker```
2. Go to directory
```cd qplotmarker```
3. Create and go to the build directory
```mkdir build```
```cd build```
4. Project configuration via CMake
```cmake ..```
If you need to specify a specific generator, use
```cmake -G "Visual Studio 17 2022" ..```
If you want to configure the library as static, add the option
```-DBUILD_SHARED_LIBS=OFF```
5. Build project
```cmake --build .```
6. Installing the library into the system
```cmake --install .```
By default, installation goes to /usr/local/ on Linux/macOS or C:\Program Files (x86)\ on Windows. To change the path, specify
```-DCMAKE_INSTALL_PREFIX=/your/path ```
[Library releases]: https://github.com/Mark194/qplotmarker/releases
# Integration
## QMake Integration
### 1. Add include path
INCLUDEPATH += $$PWD/thirdparty/qplotmarker/include
### 2. Link static library
LIBS += -L$$PWD/thirdparty/qplotmarker/lib -lqplotmarker
### OR compile sources directly (if needed)
SOURCES += $$PWD/thirdparty/qplotmarker/src/*.cpp
HEADERS += $$PWD/thirdparty/qplotmarker/include/*.h
## CMake Integration
### Method 1: Using find_package (Recommended if installed system-wide)
```cmake```
```find_package(qplotmarker REQUIRED)```
```target_link_libraries(your_target PRIVATE qplotmarker::qplotmarker)```
### Method 2: Manual configuration (For custom locations)
```
# For header files
target_include_directories(your_target PRIVATE
path/to/qplotmarker/include
)
# For static library
target_link_libraries(your_target PRIVATE
path/to/qplotmarker/lib/libqplotmarker.a
)
# Or for shared library
target_link_libraries(your_target PRIVATE
path/to/qplotmarker/lib/libqplotmarker.so
```
### Method 3: Using FetchContent (For direct GitHub integration)
```
include(FetchContent)
FetchContent_Declare(
qplotmarker
GIT_REPOSITORY https://github.com/Mark194/qplotmarker.git
GIT_TAG v1.0.0
)
FetchContent_MakeAvailable(qplotmarker)
target_link_libraries(your_target PRIVATE qplotmarker)
```
