On the same chartview I tried to show charts one by one based on the
dataset changes. For example, I have ten wells, I created a chart for well daily production, such as Gas, Oil. After show the chart for the first well, I want to continue to show chart for the second well. But the chart for the first well can't be cleaned before displaying the chart for the second well. The charts are overlapped each other. Is there a way to clean the chart before running ChartView.UpdateDraw for the second well?

You can return a ChartView to its initial state by calling the ChartView.ResetChartObjectList() method. If you call the ChartView.UpdateDraw method after this call the chart will be empty. If you add new objects prior to the ChartView.UpdateDraw call only the new objects will show up.
