I want to show %10 empty space in the plot area. Say that my largest element in the set is 12, and the lowest is 4.4
My plot's y axis should be between 4 and 13.2
How can i achieve this

Hi,
There are a few ways.
I would get the x and y axis, and use the setRange(double, double) function (there are other arguments you could use). So something along the lines of:
Qh->yAxis->setRange(4, 13.2); //using your example.
Qh->xAxis->setRange(xlower, xupper);
If you have multiple plotables, then you'd have to retrieve the plotable with Qh->graph(plotable_index) and get the two axis using a similar method.

I always do this:
plot->xAxis->scaleRange(1.1, plot->xAxis->range().center()); plot->yAxis->scaleRange(1.1, plot->yAxis->range().center());
Of course after calling rescaleAxes()
i'm sorry, i forgot to mention that i am using real time data to plot.
The problem is, i do not know in where i should scale my graphs. If i call scaleRange() whenever i update my plots, the plot is shrinking continuously, and this is not surprise of course.
Like I said, call rescaleAxes before doing the scaleRange. And if you plot realtime data, just do that before every replot.
Ok, this is what i do :
plot->graph(0)->rescaleValueAxis(true); plot->yAxis->scaleRange(1.1, plot->yAxis->range().center()); plot->replot();
With this code, my plot is shrinking continuously, the value range is growing repeatedly.
plot->graph(0)->rescaleValueAxis(false); plot->yAxis->scaleRange(1.1, plot->yAxis->range().center()); plot->replot();
the false enables the shrinking of the range, zooming your plot.
I have the same problem and your solution doesn't work.
I am using real-time data for the plot. When data is constant range is continuously growing.
custom_plot->yAxis->scaleRange(1.1f, custom_plot->yAxis->range().center());
