Unsolved How to make point's text lable adjust with scale of x-axis and y-axis in QCustomPlot?
-
x[0] = 10;
y[0] = 50;x_offset = 0.7;
y_offset = 1.0;
QCPItemText *textLabel = new QCPItemText(ui->widget);
textLabel->position->setCoords(x[0]- x_offset, y[0] + y_offset); // place position at center/top of axis rect
textLabel->setColor(Qt::white);
QString str;
str.sprintf("%d", 10);
textLabel->setText(str);
textLabel->setFont(QFont(font().family(), 8)); // make font a bit largerThe problem is , if x-axis range is (-20,20), y-axis range is (-50,100), the text lable is near the point(x[0],y[0]) properly. when x-axis range is set to (-200,200), y-axis range is set to (-500,500), the lable is merge with point(x[0],y[0]) because of large scale, what I want is lable's postion is near the point from the eye of view
how to solve this problem? for this kind of problem,MATLAB solved it perfectly, point and its lable are
displayed rightly under different scale of x-axis and y-axis -
