 + detect installation of Qwt (using environment variable QWT_ROOT) or download it and build,
 + compile library and create binaries.
 
 **TIP**: remember to set properly `CMAKE_PREFIX_PATH` env variable to let CMake `find_package` command work. It should have Qt installation path.

 # Usage
-Easiest way is to check examples subproject where you can find how to create and interact with each plot and notched marker.  
-Alternatively tests subproject can be checked. Usage also can be found in my other project called Volbx where plots from this library are used.

 # Plots
-Set of plots based on Qwt library. Each plot can be used as a widget with data delivered via public slot. Grouping plot UI additionally interact with calling code via one signal. Each plot consist mechanisms like magnifying, navigating, resetting, displaying current coordinates and showing tool tip with summary after hovering mouse.

 ## Quantiles
 ![Alt text](QuantilesPlot.png?raw=true "Quantiles Plot")  
-Plot showing quantiles (Q10, Q25, Q50, Q75, Q90) along with minimum, maximum and mean. Optionally small legend at left side can be activated. Legend hides when size of plot is smaller than hardcoded pixel threshold.   
-Number of items is displayed at the bottom.

 Plot showing quantiles (Q10, Q25, Q50, Q75, Q90) along with minimum, maximum and mean categorized according to trait type. 
-Trait example would be shape for geometrical figures or color for cars. Name of trait is displayed at the bottom together with number of items. Details are displayed after hovering above each notched marker.  
-Scales are drawn at the left and right edge of plot.

-Quantiles and grouping plot packed together along with combo box for picking trait. Quantiles plot is showing summary data, each notched marker on group plot is showing quantiles for each trait type. Proportion of area used for each plot can be changed by dragging handle placed between plots. Dragging handle to any side results in hiding one of plots.
