#### 效果演示
![效果演示](https://images.gitee.com/uploads/images/2021/0728/092100_d86629eb_7918188.gif "ohosplot.gif")

#### 安装教程
                                
1.在项目根目录下的build.gradle文件中，
 ```gradle

	allprojects {
	    repositories {
	        maven {
	            url 'https://s01.oss.sonatype.org/content/repositories/releases/'
	        }
	    }
	}
 ```

2.在entry模块的build.gradle文件中，
 ```gradle

	 dependencies {
	    implementation('com.gitee.chinasoft_ohos:ohosplot:1.0.0')
	    ......  
	 }
```

在sdk6，DevEco Studio 2.2 Beta1下项目可直接运行
如无法运行，删除项目.gradle,.idea,build,gradle,build.gradle文件，
并依据自己的版本创建新项目，将新项目的对应文件复制到根目录下

#### 使用说明

使用该库非常简单，只需查看提供的示例的源代码。

```初始化xml

    <com.ohosplot.xy.XYPlot
        ohos:id="$+id:plot"
        ohos:height="match_parent"
        ohos:width="match_parent"
        ohos:weight="1"
        app:domainTitle="domain"
        app:styleType="APDefactoDark"
        app:lineLabelRotationBottom="-45"
        app:lineLabels="left|bottom"
        app:rangeTitle="range"
        app:title="A Simple XY Plot"/>
```


```示例使用java

        // initialize our XYPlot reference:
        plot = (XYPlot) findComponentById(ResourceTable.Id_plot);

        // create a couple arrays of y-values to plot:
        final Number[] domainLabels = {1, 2, 3, 6, 7, 8, 9, 10, 13, 14};
        Number[] series1Numbers = {1, 4, 2, 8, 4, 16, 8, 32, 16, 64};
        Number[] series2Numbers = {5, 2, 10, 5, 20, 10, 40, 20, 80, 40};

        // turn the above arrays into XYSeries':
        // (Y_VALS_ONLY means use the element index as the x value)
        XYSeries series1 = new SimpleXYSeries(
                Arrays.asList(series1Numbers), SimpleXYSeries.ArrayFormat.Y_VALS_ONLY, "Series1");
        XYSeries series2 = new SimpleXYSeries(
                Arrays.asList(series2Numbers), SimpleXYSeries.ArrayFormat.Y_VALS_ONLY, "Series2");

        // create formatters to use for drawing a series using LineAndPointRenderer
        // and configure them from xml:
        LineAndPointFormatter series1Format =
                new LineAndPointFormatter(this, new PointCfgBean(5,
                        Color.getIntColor("#00AA00"), Color.getIntColor("#007700"),
                        Color.getIntColor("#00000000"), 20,Color.getIntColor("#CCCCCC")));

        LineAndPointFormatter series2Format =
                new LineAndPointFormatter(this, new PointCfgBean(5,
                        Color.getIntColor("#0000AA"),
                        Color.getIntColor("#000099"), Color.getIntColor("#00000000"),
                        20,Color.getIntColor("#CCCCCC")));

        // add an "dash" effect to the series2 line:
        series2Format.getLinePaint().setPathEffect(new PathEffect(new float[]{
                // always use DP when specifying pixel sizes, to keep things consistent across devices:
                PixelUtils.vpToPix(20),
                PixelUtils.vpToPix(15)}, 0));

        // (optional) add some smoothing to the lines:
        series1Format.setInterpolationParams(
                new CatmullRomInterpolator.Params(10, CatmullRomInterpolator.Type.Centripetal));

        series2Format.setInterpolationParams(
                new CatmullRomInterpolator.Params(10, CatmullRomInterpolator.Type.Centripetal));

        // add a new series' to the xyplot:
        plot.addSeries(series1, series1Format);
        plot.addSeries(series2, series2Format);
        plot.getGraph().getLineLabelStyle(XYGraphWidget.Edge.BOTTOM).setFormat(new Format() {
            @Override
            public StringBuffer format(Object obj, @NonNull StringBuffer toAppendTo, @NonNull FieldPosition pos) {
                int i = Math.round(((Number) obj).floatValue());
                return toAppendTo.append(domainLabels[i]);
            }

            @Override
            public Object parseObject(String source, @NonNull ParsePosition pos) {
                return null;
            }
        });

```
