Plots illustrating the waveform of the selected Equation are occasionally undersampled.
We could accurately trace out their shape by changing the sampling rate based on the Equation parameters and the main variable range (i.e. space or time) selected in the UI.
To fix this, a new framework method would be required for the Equations dataypes.
At present, this issue mainly concerns the periodic Equations.
For instance, the frequency parameter should be identified and the required sampling rate (Nyquist rate) should be set accordingly.
The `var` range will define the number of points where the equation is evaluated.
