MEChartLib

add ScrollBarView,PointView and usage usage: 1.main.xml

        <com.me.chartlib.view.CommonBarChart

            android:layout_width="match_parent"

            app:comTextColor="@color/yellow"
            app:xyLineColor="@color/yellow" />

引入使用：自己新建一个工程，在主module的build.gradle中的dependencies节点中加入依赖

Step 1. Add it in your root build.gradle at the end of repositories:

allprojects {

repositories {

 maven { url 'https://jitpack.io' }

}

}

Step 2. Add the dependency

dependencies {

implementation 'com.github.dongwang8688:MEChartLib:1.0.1'

}

再gradle synchronize一下，在工程中调用库中的任意一个API，如果只提示导包，而不是报错，则表示添加依赖成功。
