I want to redraw my real time graph, but every time I do I can still see the old ones behind it, which distorts my drawing. How do I make it refresh itself so that I can redraw it without the old one being still being visible. |

The ChartView keeps track of all chart objects added to it. If you are recreating the chart by recreating all new chart objects, then you will need to delete the previous ones from the ChartView. You can delete all of them calling the ChartView.ResetChartObjList method.
In our examples it would be something like:
chartVu.ResetChartObjList();
You are probably doing something wrong if you need to do this. YOu should be able to change the existing Chart objects, rather than recreating them all and adding them the ChartView again. But you can do it either way.
