Change X axis values.

[Georgio]

My question might be silly. I'm new to this.

In the image that I attached, you can see that I'm not doing anything special. Just some basic stuff.

What I want to do is to change the values "1", "2", "3", "4" on the X axis.

These values are generated automaticly and I don't know how to change them / disable them.

Here is my xaml.

Let's say that instead of "1" I want "25". How do I do that?

Hello Georgio,

Thank you for your interest in RadControls for WindowsPhone!

The objects that can be displayed on a RadCartesianChart with a CategoricalAxis are represented by the CategoricalDataPoint class. It has a Value and Category properties that define the position of the point on the chart. If you do not set a Category property, its value will be auto-generated in the same order that the CategoricalDataPoint is added to the DataPoints collection. The Category is of type object, and the axis label is its string representation.

In the provided example you have to set the Category property of the data points:

<chart:LineSeries.DataPoints>
    <chartEngine:CategoricalDataPoint Value="107" Category="25"/>
    <chartEngine:CategoricalDataPoint Value="105" Category="lion"/>
    <chartEngine:CategoricalDataPoint Value="106" Category="apples"/>
    <chartEngine:CategoricalDataPoint Value="102" Category="28"/>
</chart:LineSeries.DataPoints>

I hope this was useful. Please, feel free to reach back to us with further questions.

I wanted to do a similar thing too. Is there anyway to do it in the c# code?

Hi,

Yes, these classes can be created also in c#. For example: 

RadCartesianChart chart = new RadCartesianChart();
LineSeries series = new LineSeries();
series.DataPoints.Add(new CategoricalDataPoint(){ Value = 10, Category = "first"});
chart.Series.Add(series);

Let me know should you have any questions.
