LightningChart Support Forums

Hello.
I use LightningChart for WinForms and I need to fix asix X at zero on asix Y.
You can see what I want to reach on the attached screenshot
Could you give me some advice about it?
I've done it with Postion property changing but it's very complicated way, I think.
I hope in LC we can find more simple solution

Thank you in advance.

Hi

You can do this most easily like this:

m_chart.ViewXY.AxisLayout.XAxisAutoPlacement = XAxisAutoPlacement.Off;
m_chart.ViewXY.XAxes[0].VerticalAlign = AlignmentVertical.Center;
m_chart.ViewXY.YAxes[0].RangeChanged += new AxisBase.RangeChangedHandler(ExamplePointLineSeriesXY_RangeChanged);

void ExamplePointLineSeriesXY_RangeChanged(double newMin, double newMax, AxisBase axis, ref bool cancelRendering)
{
cancelRendering = true;
double trackLevel = 0;
m_chart.ViewXY.XAxes[0].Position = (newMax - trackLevel) / (newMax-newMin) * 100.0;
}

[/code]

I hope this helps...

Thank you, I'll try it.
