70 | ###LeafLineChart使用
71 |
72 | ``` java
73 |
78 |
79 | ```
80 |
81 |
82 | 初始化X轴数据：
83 | ``` java
84 | private List getAxisValuesX(){
85 | List axisValues = new ArrayList<>();
86 | for (int i = 1; i <= 12; i++) {
87 | AxisValue value = new AxisValue();
88 | value.setLabel(i + "月");
89 | axisValues.add(value);
90 | }
91 | return axisValues;
92 | }
93 | ```
94 |
95 |
96 | 初始化Y轴数据：
97 | ```java
98 | private List getAxisValuesY(){
99 | List axisValues = new ArrayList<>();
100 | for (int i = 0; i < 11; i++) {
101 | AxisValue value = new AxisValue();
102 | value.setLabel(String.valueOf(i * 10));
103 | axisValues.add(value);
104 | }
105 | return axisValues;
106 | }
107 | ```
108 |
109 | 初始化点数据和相关设置：
110 | ```java
111 | private Line getFoldLine(){
112 | List pointValues = new ArrayList<>();
113 | for (int i = 1; i <= 12; i++) {
114 | PointValue pointValue = new PointValue();
115 | pointValue.setX( (i - 1) / 11f);
116 | float var = (float) (Math.random() * 100);
117 | pointValue.setLabel(String.valueOf(var));
118 | pointValue.setY(var / 100);
119 | pointValues.add(pointValue);
120 | }
121 |
122 | Line line = new Line(pointValues);
123 | line.setLineColor(Color.parseColor("#33B5E5")).setPointColor(Color.YELLOW).
124 | setCubic(false).setPointRadius(3).setHasLabels(true)
125 | .setFill(false);
126 | return line;
127 | }
128 | ```
129 |
130 | 图表设置数据：
131 | ```java
132 |
133 | Axis axisX = new Axis(getAxisValuesX());
134 | axisX.setAxisColor(Color.parseColor("#33B5E5")).setTextColor(Color.DKGRAY).setHasLines(true);
135 | Axis axisY = new Axis(getAxisValuesY());
136 | axisY.setAxisColor(Color.parseColor("#33B5E5")).setTextColor(Color.DKGRAY).setHasLines(true).setShowText(true);
137 | lineChart.setAxisX(axisX);
138 | lineChart.setAxisY(axisY);
139 | List lines = new ArrayList<>();
140 | lines.add(getFoldLine());
141 | lines.add(getCompareLine());
142 | lineChart.setChartData(lines);
143 |
144 | lineChart.showWithAnimation(3000);
145 |
146 | //无动画
147 | //lineChart.show();
148 | ```
149 |
150 | ###SlideSelectLineChart使用
151 |
152 | 初始化X轴数据（注意：如果想在滑动选值的时候能正确返回点对应x轴刻度，不要忘了调用`setLabel`方法）：
153 | ``` java
154 | private List getAxisValuesX(){
155 | List axisValues = new ArrayList<>();
156 | for (int i = 1; i <= 12; i++) {
157 | AxisValue value = new AxisValue();
158 | value.setLabel(i + "月");
159 | axisValues.add(value);
160 | }
161 | return axisValues;
162 | }
163 | ```
164 |
165 |
166 | 初始化Y轴数据：
167 | （同上）
168 |
169 | 初始化点数据和相关设置：
170 | （同上）
171 |
172 | 初始化标尺线：
173 |
174 | ```java
175 | private SlidingLine getSlideingLine(){
176 | SlidingLine slidingLine = new SlidingLine();
177 | slidingLine.setSlideLineColor(getResources().getColor(R.color.colorAccent))
178 | .setSlidePointColor(getResources().getColor(R.color.colorAccent))
179 | .setSlidePointRadius(3);
180 | return slidingLine;
181 | }
182 |
183 | ```
184 |
185 | 图表设置数据：
186 |
187 | ```java
188 |
189 | private void initLineChart() {
190 | Axis axisX = new Axis(getAxisValuesX());
191 | axisX.setAxisColor(Color.parseColor("#33B5E5")).setTextColor(Color.DKGRAY).setHasLines(false).setShowText(false);
192 | Axis axisY = new Axis(getAxisValuesY());
193 | axisY.setAxisColor(Color.parseColor("#33B5E5")).setTextColor(Color.DKGRAY).setHasLines(false).setShowText(true);
194 | slideSelectLineChart.setAxisX(axisX);
195 | slideSelectLineChart.setAxisY(axisY);
196 |
197 | slideSelectLineChart.setSlideLine(getSlideingLine());
198 | slideSelectLineChart.setChartData(getFoldLine());
199 | slideSelectLineChart.show();
200 | }
201 |
202 | ```
203 |
204 |
205 |
206 |
207 | ## 二、直方图
208 |
209 | 使用类似折线图
210 |
211 | ### 设置
212 | - `Square.setWidth` 直方图宽度
213 | - `Square.setBorderWidth` 边框宽度
214 | - `Square.setBorderColor` 边框颜色
215 | - `Square.setFill` 是否填充
216 | - `Square.setHasLabels` 是否有标签
217 | - `Square.setLabelColor` 标签背景色
218 | - `Square.setLabelRadius` 标签弧度
219 |
220 |
221 | ### 效果图
222 |
