Hello, Zake,  

You can achieve the chart from the provided screenshot by using an inverse axis. The IsInverse property of the abstract LineAxis class determines whether an axis of a RadChartView will be reversed. In certain areas in engineering or physics it is a standard for some data representation an axis to be inverse. Please refer to the following help article: https://docs.telerik.com/devtools/winforms/controls/chartview/axes/inverse-axis

I hope this information helps.

thank you for the answer, but I still have a question, 

what if the value on the axis y is positive and negative, the chart like image that I attach below

Hello, Zake,    

By default, RadChartView doesn't render the positive values from bottom to top and the negative values in reversed direction. The following KB article shows how you can paint a chart where the area is started from zero. This means that the positive values will go up and the negative down: https://docs.telerik.com/devtools/winforms/knowledge-base/negative-area-chart

Note that this is just a sample approach and it may not cover all possible cases. Feel free to modify it in a way which suits your requirement best.

I hope this information helps.
