[英]How to plot more than one graph on JFreechart graph
我正在一個arduino項目中,我應該使用串行讀取來繪制圖形。 我正在使用JFreechart。 在我的代碼中,我只能繪制一個圖形。 但是我需要在同一張圖上繪制4個或多個圖。
我得到了一些以“,”為界的數值。 以下是代碼。 請幫助我繪制4個或多個圖形。 我可以繪制一張,但不能超過一張。

您的程序未正確同步,因為它從事件分配線程以外的線程更新Swing GUI組件。 使用此處所示的SwingWorker
來收集doInBackground()
實現中的數據, publish()
中間結果,並更新process()
實現中的每個系列,這將在事件分發線程上調用。 您可以add()
值的個體XYSeries
組成的XYSeriesCollection
,如圖所示這里 。
