问题 Edit: I changed the title because isn't about MPAndroidChart, the same issue would happen with another view below the ListView.

MPAndroidChart绘制图形表

最近一个项目需要用到表格进行统计显示，本来用的是的achartengine，后来发现一个更加强大的开源框架MPAndroidChart。 下面简单介绍下MPAndroidChart，MPAndroidChart的效果还是蛮好的，提供各种动画，这个也是我使用MPAndroidChart，而且放弃achartengine的原因。 Github地址连接，后面是youtube上面演示MPAndroidChart的视频，MPAndroidChart由于提供了动画效果，为了兼容低版本的Android系统，MPAndroidChart需要添加nineoldandroids-2.4.0-2.jar作为依赖库，所以如果项目中使用这个表格库，需要同时导入这个两个jar，当然如果使用libproject的方式，就不用了。 https://github.com/PhilJay/MPAndroidChart https://www.youtube.com/watch?v=ufaK_Hd6BpI http://nineoldandroids.com/ 核心功能: 支持x，y轴缩放 支持拖拽 支持手指滑动 支持高亮显示 支持保存图表到文件中 支持从文件（txt）中读取数据 预先定义颜色模板 自动生成标注 支持自定义x，y轴的显示标签 支持x，y轴动画 支持x，y轴设置最大值和附加信息 支持自定义字体，颜色，背景

MPAndroidChart how to change the color of the bar chart past the limit line?

由 时光毁灭记忆、已成空白 提交于 2020-01-26 03:55:07
问题 How to change the color of the bar chart past the limit line? Now, bars that cross the limit line change color. But, I want to change the color of the part cross the limit line. 回答1: I think you can achieve that with stackedBarChart . Here in the docs you can see how to add the data for each bar. With this, you will set the data for a barchart as follows: BarEntry(xPosition, floatArray(belowLineNumber, aboverLineNumber) For the colors, you just need to add a list of colors fot the data set

问题 I want to create a small application with a schedule. But for some reason, when I add a lot of points to the chart, it simply does not appear, although with a small number of points everything works. void f() { ArrayList<Entry> values = new ArrayList<>(); for (int i = x1, index = 0, j = y; i < x2; ++i, ++index) { float waveLength = (float) calib_a * i + (float) calib_b; int pixel = rotated.getPixel(i, j); float I = (Color.red(pixel) + Color.blue(pixel) + Color.green(pixel)) / 765.0f; values

MPAndroid Line Chart single data point with curve

由 百般思念 提交于 2020-01-15 09:06:46
问题 I want linechart as follows. I want to show only specified point (blue circled should be there) (red circled should not be there). 回答1: I think of 2 methods. First: disable all points and values with lineDataSet.setDrawValues(dataSet.drawValues); lineDataSet.setDrawCircles(dataSet.drawValues); Then add another LineDataSet to the LineChart only containing that one point for the Maximum. This solution causes an additional entry in the Legend. The other solution would be a custom MarkerView like
