here\'s instead of

Answer 1

To show the label on the axis you have to specify the property MajorStep, Oxyplot will paint only the labels matching the major step.

model.Axes.Add(new LinearAxis()
{
    MajorStep = 10,
    Position = AxisPosition.Left,
    ...
});

And to modify the labels with the day name, you can use a DateTimeAxis instead of LinearAxis:

model.Axes.Add(new DateTimeAxis()
{
    StringFormat = "ffffd",
    Position = AxisPosition.Bottom,
    ...
});

If you want something more customized you will have to use the LabelFormatter attribute.

EDIT:

Labels in CategoryAxis:

var categoryAxis = new CategoryAxis()
{
    Position = AxisPosition.Bottom,
    ...
};

categoryAxis.ActualLabels.Add("Mon");
categoryAxis.ActualLabels.Add("Tue");
categoryAxis.ActualLabels.Add("Wed");
categoryAxis.ActualLabels.Add("Thu");
categoryAxis.ActualLabels.Add("Fri");
categoryAxis.ActualLabels.Add("Sat");
categoryAxis.ActualLabels.Add("Sun");

Model.Axes.Add(categoryAxis);

CategoryAxis.ActualLabels is readOnly, so you will have to Add the items one by one.
