wpf graph: axis label formatting

[eugenem]

How do I configure the graph to show only first and last label on the axis? I think it's somehow should be done by modifying RangeLabeledDivisions.Mode property...

                     <ni:AxisDouble x:Name="horizontalAxis1" Orientation="Horizontal" Label="X" BaselineStroke="{x:Null}">
                        <ni:AxisDouble.MinorDivisions>
                            <ni:RangeDivisions TickVisibility="Hidden" />
                        </ni:AxisDouble.MinorDivisions>
                        <ni:AxisDouble.MajorGridLines>
                            <ni:GridLines Stroke="{StaticResource GraphGridLinesColorBrush}" />
                        </ni:AxisDouble.MajorGridLines>
                        <ni:AxisDouble.MajorDivisions>
                        <ni:RangeLabeledDivisions TickVisibility="Hidden">
                            <ni:RangeLabeledDivisions.LabelPresenter>
                                <ni:GeneralValueFormatter Format="0.00" />
                            </ni:RangeLabeledDivisions.LabelPresenter>
                        </ni:RangeLabeledDivisions>
                    </ni:AxisDouble.MajorDivisions>
                </ni:AxisDouble>

You can set the Mode on the MajorDivisions to a Count mode of two:

    <ni:AxisDouble.MajorDivisions>
        <ni:RangeLabeledDivisions Mode="Count: 2" TickVisibility="Hidden">
                ...
        </ni:RangeLabeledDivisions>
    </ni:AxisDouble.MajorDivisions>

This will show just the minimum and maximum divisions for the range.

thanks!

How do I make left label aligned left at 0 and right label aligned right at max? Now they both are aligned center.

Have a look at this question.

[eugenem]

got it, works!

Another clarification: when I use count:2, all gridlines are also gone. How can I get both gridlines and 2 labels?

The grid lines are tied to the major divisions shown by the axis. To show the divisions without the labels, you can leave Mode set to Auto and use the opacity technique from the hide labels question, switching the logic so the opacity is changed for the non-extreme labels.
