Usage

Builder

SegmentedBarView barView = SegmentedBarView.builder(this)
                           .segments(segments)
                           .value(5.25f)
                           .unit("ml<sup>2</sup>")
                           .showDescriptionText(true)
                           .sideStyle(SegmentedBarViewSideStyle.ANGLE)
                           .build();

Constructor and setters

SegmentedBarView barView = new SegmentedBarView(this);
barView.setValueWithUnit(4.96f, "10<sup>12</sup>/l"); /* You can use Html tags here in unit to support superscript and subscript */
barView.setSegments(segments);

Within xml layout

<mobi.gspd.segmentedbarview.SegmentedBarView
        android:id="@+id/bar_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="20dp"
        app:sbv_empty_segment_text="No segments"
        app:sbv_segment_gap_width="10dp"
        app:sbv_segment_text_size="20sp"
        app:sbv_show_description_text="true"
        app:sbv_side_style="angle"
        app:sbv_side_text_style="twoSided"
        app:sbv_value_sign_height="30dp"
        app:sbv_value_sign_round="8dp"
        app:sbv_value_sign_width="30dp" 
/>

Create segments

In any case you should create segments list to put in view.

List<Segment> segments = new ArrayList<>();
Segment segment = new Segment(0, 4.5f, "Low", Color.parseColor("#EF3D2F"));
segments.add(segment);
Segment segment2 = new Segment(4.5f, 6.5f, "Optimal", Color.parseColor("#8CC63E"));
segments.add(segment2);
Segment segment3 = new Segment(6.5f, 20f, "High", Color.parseColor("#EF3D2F"));
segments.add(segment3);

Each segment contains min and max value, color, description text (optional), custom text (optional). Value sign position is calculated automatically in these intervals.

Also there can be segments with no min and max. Then you should set valueSegment field of SegmentedBarView, it's just an index of segment to show value sign over.
