问题描述:

I have made the plot to repaint the graph from the first once it reaches end. Now my problem is the graph gets overwritten. The previous plot remains as such. So, how should i repaint after clearing the previous plot? And by clearing i should not loose the previous data. It should remain as such when i scroll.Can someone help me with this pls?

网友答案:

I will try to answer the questions I understood:

  • You can clear data from the previous series, by removing it
  • You can control the visible area by using renderer.setXAxisMin() and renderer.setXAxisMax()
  • When you want the cursor sent back to the beginning, you can create a new series and start adding data to this series
  • You can hide the legend, if you don't need it by calling renderer.setShowLegend(false)

The changes will be visible on the screen after calling chartView.repaint().
