Need to move -90 rotated x-axis away from the axis grid

[rhb327]

My chart and x-axis setup is below. I'm building this chart in memory and then do a grab and convert to a BMP for thermal printing. My issues is my x-axis -90 label is too close to the grid and overwrites for larger numbers. I've tried to change the label format (even adding a space!), setMargins() and setContentMargins() to adjust without much success. setMargins() seems to give me more space from chart border to start of the x-axis -90 label but not more space from the start of the x-axis -90 label to the axis grid line. I use setContentMargins() to zoom a smidge to get rid of the chart border before I grab it.

Any ideas on this?

    chart.setDropShadowEnabled(false);

    // These are the ones where I think I add pad from edge of chart to x-axis label start but does
    // not appear to add distance from left of x-axis label start to x-axis grid
    chart.setMargins(QMargins(50, 3, 10, 50));
    chart.setContentsMargins(-10, -10, -10, 0);

    chart.setAutoFillBackground(true);
    chart.setBackgroundBrush(QBrush(Qt::white));
    chart.setBackgroundPen(QPen(Qt::black, 2, Qt::SolidLine));
    chart.setPlotAreaBackgroundBrush(QBrush(Qt::white));
    chart.setTitle("");
    chart.legend()->hide();

    axisX.setLabelFormat("0%5.1f ");
    axisX.setLabelsColor("#FFFFFF");
    axisX.setTitleVisible(false);
    axisX.setTitleText("");
    axisX.setLabelsBrush(QBrush(Qt::black));
    axisX.setTitleBrush(QBrush(Qt::black));
    axisX.setLinePen(QPen(Qt::black, 2, Qt::SolidLine));
    axisX.setGridLinePen(QPen(Qt::black, 2, Qt::DotLine));
    axisX.setLabelsFont(QFont("NotoSans", 9, QFont::Bold, false));

    chart.addAxis(&axisX, Qt::AlignBottom);

    axisX.applyNiceNumbers();
    axisX.setLabelsAngle(-90);
