Setting a min value of an axis in Live Charts graph

Question

I'm using Live Charts library and I've run into a problem where the y axis has "-1000" as the min value.

How do I set this to 0? I tried in the winforms under the Yaxis collection and setting MinValue to 0 there but that doesn't seem to do anything.

This is how I draw the chart:

cartesianChart1.Series.Add(
    new LineSeries
    {
        Title = "Series 1",
        Values = graph1.ReturnGraphData().AsChartValues(),
        LineSmoothness = 0, //straight lines, 1 really smooth lines
        PointGeometry = null,
        PointGeometrySize = 0,
    });

the method "ReturnGraphData()" returns an int-array.

Also this are my settings of the YAxis in winforms designer:

Like i said earlier when I set MinValues to 0 in the properties it either doens't do anything or crashes Visual Studio. It also reverts to NaN.

Can you also post some code? It is not possible to see the problem with the picture. — Yvonnila, Nov 10 '17 at 07:02

I found a way that works:

        cartesianChart1.AxisY.Clear();

        cartesianChart1.AxisY.Add(
        new Axis
        {
            MinValue = 0 
        });

        cartesianChart1.Series.Add(
        new LineSeries
        {
            Title = "Series 1",
            Values = model.ImageGraphData().AsChartValues(),
            LineSmoothness = 0, //straight lines, 1 really smooth lines
            PointGeometry = null,
            PointGeometrySize = 0,
        });

In this code sample I'm clearing all the existing YAxis and then adding one with MinValue = 0. What I was doing wrong before was trying to add a new YAxis after the graph was drawn, which didn't seem to work. However the fact that setting MinValue = 0 in the WinForms designer doesn't work is still weird to me.
