Neu in Version 2019 – Origin 2019: Cluster Plot for Grouped Data

Cluster Plot for Grouped Data in Origin 2019

Trellis plot was introduced in Origin 2017 to present data in multiple panels. This plotting method is very useful if data is grouped with grouping information in one or two columns like below. While one drawback of trellis plot is that the X, Y scales have to be identical among panels. In Origin 2019 a new plot type called cluster plot is introduced, with which the user has more flexibility in plotting grouped data in multiple panels. Two main advantages are:

  1.  X,Y scales can be different among panels.
  2. User can choose to hide certain groups of data in the graph.
