Hi I am using Ms chart control in winforms application for displaying values according to dates
I need to change the x-axis label values(Dates) direction horizan
If you have not already done so, get the chart samples from microsoft:

Then check the section on Labels
Chart Features > Labels
To answer your question directly, set the angle in LabelStyle, and don't forget to disable autofit
chartArea1.AxisX.IsLabelAutoFit = false;
chartArea1.AxisX.LabelStyle.Angle = 90;
