Humidity ratio and dew point lines run completely horizontal. Moving left or right along a horizontal line represents sensible heating or cooling, where temperature changes but total moisture content remains constant. Diagonal Lines psychometric chart

The psychrometric chart converts complex thermodynamic equations into an intuitive visual tool. With practice, any HVAC or environmental process can be rapidly modeled, understood, and optimized by plotting state points and connecting process lines on the chart.
The psychrometric chart is a graphical representation of the thermodynamic properties of moist air. It is an essential tool for HVAC engineers, meteorologists, and building scientists to visualize and calculate air conditioning, drying, and humidification processes.
