Modify the Cursor Value/Label in wpf

[Flow75]

Hello,

I have a graph from NI Measurement Studio 2013 WPF

I've insered a cursor into it.

I would like to show the cursor value but only the x value.

How to do this ?

If you want a single interactive line, consider using a MultiPlotCursor instead of a Cursor. This can be configured to only show the value of the horizontal axis by excluding association with any plots (using an empty include list):

<ni:MultiPlotCursor AllowablePlots="Include:" />

Otherwise, you would need to create a custom class to use as the ValuePresenter for the cursor, and have it only display the first dimension of incoming data. Something like this:

protected override string FormatCore<TData>( TData value, ValuePresenterArgs args ) {
    string result =
        value is IList dimensions
            ? DimensionFormatter.Format( dimensions[0], args )
            : DimensionFormatter.Format( value, args );
    return result;
}

Hello Phansen,

Thank you for the answer.

For the second solution, I don't understand your solution. 🤔.

the Cursor.ValuePresenter property type is ValuePresenter and I don't understand how to use your proposition.

Thx.

Sorry for the isolated example code! Attached is a complete implementation of a custom value presenter class.

Hello,

sorry for the delay, some other stuffs to take care 😋.

I've finally managed to integrate your code into my application

Some adaptation to downgrade into c# 4.8 but all is ok !

Thx very much.
