Dear Luzia. Unfortunately, Chart FX API does not provide a property to customize Label text area height. You should reduce the text you are currently sending to axis labels. As a workaround, you can change label angle (chart1.AxisX.LabelAngle = 45;). I hope this helps.

Dear Xiaonan Ji. You need to use XY chart to avoid this behavior. Unfortunately, Chart FX engine will draw only lines between visible points inside the zoomed area.
