# Psychrometric Chart **Clima** allows the user to visualize all annual weather conditions on a [psychrometric diagram.](/clima/documentation/tabs-explained/psychrometric-chart/psychrometric-chart-explained.md) The default diagram allows the users to overlay the frequency with which weather conditions recur throughout the year.

Example: Frequency of climatic condition in the Psychrometric chart of **New York, USA**

With the first choice in the drop-down list, "None", it is possible to view temperature conditions in the psychrometric diagram over the entire year. The visualized dots have the same gradient with a transparency rate, they are not colored according to a legend. Multiplying them when overlaid provides a visualization of their frequency, so the most common conditions.

Example: Psychrometric chart with climatic conditions of **New York, USA**

Then, users can overlay another variable on the graphs, choosing from [Clima dataframe](/clima/documentation/tabs-explained/tab-summary/clima-dataframe.md).

Example: Psychrometric charts with different variables (from top left to bottom right): dry bulb temperature, relative humidity, global horizontal radiation, and wind speed

Moreover, data can be filtered by date, time, or one of the [Clima dataframe](/clima/documentation/tabs-explained/tab-summary/clima-dataframe.md) variables.
