Problem 1.
like image, X line is long, Y line is middle and Z line is too short.
My wanted Graph is abolutely same width in three lines.
My code is like this.
m_graph->axisX()->setRange(0, 256);
m_graph->axisY()->setRange(0, 1000);
m_graph->axisZ()->setRange(0, 60);

How do to make the size look the same as a whole?

Problem 2.
