Line chart of HelloCharts open source chart Library (1), hellocharts Open Source

We have introduced the open-source chart library MPAndroidChart. For details, refer:

Http://blog.csdn.net/shineflowers/article/details/44704723

We will introduce a better chart library today, which provides better performance, better functions, more beautiful UI style, and more precise coordinate axes than MPAndroidChart.

• Supports scaling, sliding, and translation. Zoom (pinch to zoom, double tap zoom), scroll and fling

• Supports custom coordinate axes (for example, the coordinate axes are located in the upper, lower, and left sides) and Automatic Generation of coordinate axes. Custom and auto-generated axes (top, bottom, left, right, inside)

• Animation (Animations)

• Preview is supported, that is, there is a sub-chart with finer coordinate density under the chart, and a region of the sub-chart is selected. The chart above the sub-chart will show more details of the selected area.

• GitHub address:

• Https://github.com/lecho/hellocharts-android
  

• The line chart is as follows:

• 1. download the latest hellocharts-library-1.5.3.jar package from the address above and copy it to the libs of the project

  2. Define an xml file

• 
  

• 3. Some logics for displaying a line chart are as follows:

  For (int I = 0; I <10; I ++) {mPointValues. add (new PointValue (I, new Random (). nextInt (10); mAxisValues. add (new AxisValue (I ). setLabel (I); // set the corresponding label for each corresponding I (displayed on the X axis)} Line line = new Line (mPointValues ). setColor (BLUE ). setCubic (false); List <Line> lines = new ArrayList <Line> (); lines. add (line); LineChartData data = new LineChartData (); data. setLines (lines); // Axis axisX = new Axis (); // the X Axis axisX. setHasTiltedLabels (true); axisX. setTextColor (BLUE); axisX. setName ("collection time"); axisX. setMaxLabelChars (10); axisX. setValues (mAxisValues); data. setAxisXBottom (axisX); Axis axisY = new Axis (); // y Axis axisY. setMaxLabelChars (7); // The default value is 3. You can only view data of the last three digits. setAxisYLeft (axisY); // sets the behavior attribute. It supports scaling, sliding, and translating mLineChartView. setInteractive (true); mLineChartView. setZoomType (ZoomType. HORIZONTAL); mLineChartView. setContainerScrollEnabled (true, ContainerScrollType. HORIZONTAL); mLineChartView. setLineChartData (data); mLineChartView. setVisibility (View. VISIBLE );
