I am using an itemTracer to display values on the graph and tried to select the interpolating option
as follows:
tracer->setGraphKey(x); tracer->setInterpolating(true); tracer->setStyle(QCPItemTracer::tsCrosshair); tracer->setPen(QPen(x_axis_color));
My concern is about the value interpolated between two graph data.
Is there a way to retrieve this value ?
