JavaScript Stock Chart
Stock Chart is a powerful application that lets you forget about most of the boring parts in building complex statistical systems. It has built-in period and data set selection tools, and can group data to longer periods. This enables you to make drill-down charts without any additional coding, using one data file only. Click on "MAX" button below the chart and you will notice that the chart displays monthly data. Click the "1 Month" button, and you will see that the chart now displays daily data. This is done without any data reloading!
