How to plot pressure graph with respect to time in CFD-Post?

I want to plot a graph of Pressure in CFD post with respect to time. The Y-axis should contain pressure, wave elevation, velocity etc while x-axis should contain time (s).

May I know how to plot any variable like pressure, volume fraction etc with respect to time. Where I can find time variable in CFD post.

Just make a chart, and on the first tab of options, one option is transient/sequence or something like that.

Hello Ahmed,

Go to insert -> chart
in the general tab -> select type: XY - Transient or Sequence
in the X Axis tab -> select expression -> time
in the Y Axis tab -> Data Selection -> Variable: Pressure/velocity, etc... There are three dots on the right of the selection box if the variable you are looking for is not listed in the drop down menu. This is where you would select your user defined functions, such as a wave elevation.
If you wanted the readings along a line/plane, you must select the entity in the Data Series tab.
