Hello,

I am binding the ItemsSource of a ScatterLineSeries to some Linq Enumerable.
Is it possible to use the index (and not some property inside of the item) as x-coordinate?

Additionally, is it possible to specify a dot-separated path inside the XValueBinding (e.g. XValueBinding="Parent.X1")?

Thank you in advance!

Alex

Hi Alexander,

1. Is it possible to use the index (and not some property inside of the item) as x-coordinate?
If you are in a scatter mode, this is not possible (scatter mode is when you are using two linear axes and scatter series). If you are using a categorical series (and at least one categorical axis) you will achieve the desired effect by only setting the ValueBinding and not setting the CategoryBinding property at all.

2. is it possible to specify a dot-separated path inside the XValueBinding
You can use a GenericDataPointBinding:
series1.ValueBinding = new GenericDataPointBinding<YourBusinessObject, double>
{
  ValueSelector = dataItem => dataItem.Smth.Val
};

Thank you. I think that will help me.
Just one other question: Is it possible to specify an offset for the Categorical axis? So that it does not start with 1, but with any other number?

Hi Alexander,

1. Is it possible to specify an offset
When not setting a CategoryBinding, the chart internally assigns the Category of the DataPoint to be an index. Starts from 1. You cannot change this internal logic, but if you need, you can assign the CategoryBinding property and the axis will show what you need.
