mpandroidchart

问题 I am using the MPAndroidChart library. I have multiple scattercharts in a ListView. Every chart contains 365 xvalues (every day of the year). The yvalues vary from 1 to 5. The height of the charts is 150dp. I would like to be able to zoom in, so I can see every single day. But when I zoom in, the yvalues get out of range of the chart. Is there a way to keep the yvalues within range of the chart? I tried it with the next settings: holder.chart.setTouchEnabled(true); holder.chart.setDragEnabled

Since the chart is transparent by default, if you manage to get hold of the background picture like in your image, you could use the drawable and change the chart's background and tinker around with it. You could use this for your chart: In your XML : android:background="....." or setBackgroundResource(.....) in
