Radiation: In this ray is drawn from the instrument towards the point, then the distance measured is located by plotting to some scale.
Intersection/Graphic triangulation: Used when the distance between two points is large and cannot be measured accurately due to some field condition.
Traversing: Similar to theodolite traversing, the table is set up at each station in succession. Foresight is taken to the next station and the required distance is measured to a suitable scale.
Resection: This method is used when the plane table occupies a position not yet plotted on the drawing sheet. It is the process of determining the plotted positions of the station occupied by the plane table, by means of sights taken towards known points, the location of which has been plotted.

Detailed plotting is generally done by Radiation method.

Explanation:
The Radiation method is a graphical method of surveying used to locate a new point from two known points by drawing straight lines from the known points to the new point. It is also called the "angle from point" method. This method is used when the new point is inaccessible for chaining or traversing.

In this method, the angles between the known points and the new point are measured with a theodolite or a compass. The new point is located at the intersection of the two straight lines drawn from the known points to the measured angles. This method is particularly useful in hilly and mountainous terrain where chaining or traversing is difficult.

Advantages of Radiation Method:
• Easy to use and quick method.
• Suitable for locating inaccessible points.
• Requires less time and labor compared to other methods.
• More accurate than other graphical methods.

Disadvantages of Radiation Method:
• Limited to locating one point at a time.
• Errors can occur due to inaccurate angle measurement or sighting.
• Not suitable for large-scale surveying.
• Require skilled surveyors to perform accurate measurements.

Conclusion:
Detailed plotting is generally done by the Radiation method which is a graphical method of surveying used to locate a new point from two known points by drawing straight lines from the known points to the new point.
