This sample chart displays and compares the cumulative sums, today's 1-hr data and yesterday's data. The line chart of this sample displays one item of today's data every 5 seconds based on the 1-hr data. The area chart of this sample displays one item of today's data every 5 seconds based on the 25-hrs data (Yesterday, 23:00 ~ Today, 23:59). This sample chart has dual X, Y axes. The line chart displays items along the left and top axes and the area chart displays items along the right and bottom axes. After the specified period of time of displaying, the chart refreshes all of the data, which means that the chart requests yesterday's data again and requests today's data (the cumulative data). More
