Hi,

Thank you, that's working perfectly! There is just one more question about that: is it possible to make the maximum value to round up?

Regards
Daniel

Hi Daniel,

You can specify a range view where only the min or max value is regarded - for example:

chart.Axis(StandardAxis.PrimaryY).View = new NRangeAxisView(new NRange1DD(80, 0), true, false);

tells the y axis to always start from 80 and extend to whatever value is in the data.



Best Regards,

Hi,

I am trying to auto scale my graph during run time. I have two options ether the user can give min and max values of the Y axes or it should be done automatic. I have this code:

public void setAutoscale(int axisIndex, bool autoscale)
{
if (autoscale)
{
m_Chart.Axis(axisList[axisIndex].AxisId).View = new NContentAxisView();
}
else
{
m_Chart.Axis(axisList[axisIndex].AxisId).View = new NRangeAxisView(new NRange1DD(1000, 3000));
}
}

The only problem of mine is that I would like to set a minimum value of the automatic scale set like that:

m_Chart.Axis(axisList[axisIndex].AxisId).View = new NContentAxisView(0);

Is it possible to sort this out somehow (any built in method?)? I know I could write my own function to check the maximum value in every tick, but that seems a bit useless, of course if there are not any other option I will need to go with that.

Thank you for your help in advanced
Daniel
