This quick-tip demonstrates three ways in which you can avoid the “CAUTION: you have exceeded 5000 text objects” warning.
In the first I test whether there are 5000 text objects on the chart then I use the DrawingObjects.Items[4] construct to create a vector containing all the text labels created by an analysis technique, and then delete the oldest.
In the second, when a new text object is added to the chart a pointer is stored in a vector. When the vector exceeds a certain size, the oldest text object is deleted (and the corresponding vector element).
In the third the program adds new text labels up to a certain number. When that number is surpassed the oldest text object is relocated, the value is changed (and its color).
