Hello, What is the behavior of sc.DeleteACSChartDrawing if the line number does not exist? Do I always have to check if a drawing exists before a call to sc.DeleteACSChartDrawing. Does sc.DeleteUserDrawnACSDrawing have the same behavior? Thx, -WT |

No deletion takes place if the line number does not exist, with either of these functions.

I have notice my code has better performance if I use sc.ChartDrawingExists() before a call to sc.DeleteACSChartDrawing. Am I just seeing something that is not there? The example in your documentation checks if the line number exist. Why does it check if the line number exits before the call? Refer to the scsf_UseToolExample() function in the /ACS_Source/studies.cpp file for example code on how to work with this function.

Posted the wrong documentation. I meant: For an example which uses this function, refer to the scsf_DeleteACSChartDrawingExample function in the /ACS_Source/studies.cpp file in the Sierra Chart installation folder.

It generally is going to be considered best practice to check if the chart drawing exists first. We would have to see why there is a performance difference but if there is, then certainly check first. Sierra Chart Support - Engineering Level Your definitive source for support.
