 XYChart, Y axis placement of values. Can it be done automatically? |

I don't know in advance what the values to be plotted on the Y axis are. I've got a simple XY chart which I size based on the title and label font sizes. This works well for most charts, it places the plot area to fill the remaining window space. The problem is if I have some very large values on the Y axis, these overwrite the Y axis labels.
So my question is, is there a way to specify a plot area, and that plot area includes the X and Y axes? This seems like a more logical way to do things rather than the current way as you need to know the size of the labels.
Thanks in advance,
Tony.
XYChart* c = new XYChart(nBaseWidth, nBaseHeight);
int nApproxTitleSize = m_pfont_Title->GetPointSize() * scale;
int nAxisTitleSize = m_pfont_AxisLabels->GetPointSize() * scale;
int nPlotAreaX = nAxisTitleSize * 5;
int nPlotAreaY = nApproxTitleSize * 3;
int nPlotAreaW = nBaseWidth - nPlotAreaX * 2;
int nPlotAreaH = (int)(0.6 * (float)nBaseHeight);
c->setPlotArea(nPlotAreaX, nPlotAreaY , nPlotAreaW , nPlotAreaH , backgroundColour, -1, 0xc0c0c0, 0xc0c0c0, -1);

Ignore me again, I've just found the packPlotArea function.
