I am painting a series series line dynamically, all those link to its context viewmodel, now the problem is that when drawing more than one series they begin to distort, now as you can see in the image, when hidden by in the middle of a CheckBox of his legend the others and I just leave one this goes well, the first hurts the second, and the second to the third, and so on, already e checking the values, and those are correct, I think I have problems with the horizontal axis, but I don't know how to solve it. It can be seen in the image of how it looks. Here I leave the same as the xaml where I work. Can someone help me what is happening

Hello Saulo,

It turns out that this questions was raised also in a support ticket. You can find an answer there (ticked ID: 1426290). For your convenience, below you can find the the reply. I also deleted the duplicated thread in the forum.

This behavior occurs because the chart axes automatically calculate their ranges based on visible data. When you hide one of the series, the axis re-calculates its range and re-arranges the data.

To achieve your requirement you can use two approaches:

  • The first one is to replace the horizontal CategoricalAxis with a LinearAxis and manually set its range using the Minimum and Maximum properties. This way you can define a constant range and the viewport won't be changed when you hide series. In this case you will need to use the scatter version of the chart series (ScatterLineSeries in your case). 
  • The second approach is to keep the horizontal CategoricalAxis, but in this case you will need to ensure that all expected categories are loaded all of the time within the chart. To do this, you can define an additional dummy series with empty data points and each data point can have a valid category. This way when you hide a series its category will get preserved on the axis because it will be presented in the dummy series.
