我正在制作这个图形应用程序。它有一个叫做处理的应用程序。我很确定它使用Java，但它可能会略有不同，然后Java。无论如何，所以当你打开应用程序（我认为你需要有处理下载，并从正确的文件夹打开它）。
当你打开它，你会看到我的图表没有数据点和三个按钮在每一方。我有我的按钮都链接到功能和控制台，他们显示他们正在工作时，我点击他们。但我只是不知道如何显示图表（我所做的功能）与所有的图表点和标题等，当我点击按钮。有人能帮忙吗，谢谢

drawHealthGraph(); rawPopulationGraph(); ```

they all work and if I put them all in the draw function they all show
up Its just I need to click it and then when I click the next one the
first one should go away and the second one should come up
