Small values

[andrewd]

Hi,

In mpFXYVector::SetData() the following lines cause small values to display all scrunched up:

        m_minX-=0.5F;
        m_minY-=0.5F;
        m_maxX+=0.5F;
        m_maxY+=0.5F;
 
Simply removing them solves all problems (for me).

Thanks.

Also, in mpScaleY::Plot the fmt = format options are rather arbitrary. I changed it just %g for my needs.

I derived a class from mpFXYVector to allow me to set the min and max values.

That's A bit of overkill. A more general solution to solve I expect 99% of cases is:

double diffY = (m_maxY - m_minY) * 0.05f;
m_minY -= diffY;
m_maxY += diffY;

double diffX = (m_maxX - m_minX) * 0.05f;
m_minX -= diffX;
m_maxX += diffX;

Gives a bit of space at top and bottom but scales to any arbitrary precision.
