In the past, for dense data, if user turned on labels, many labels would overlap with one another and hard to read. By Auto position feature in Origin9.1,

  • Origin automatically calculates data label positions to avoid overlapping in X, Y or both directions.
  • Leader lines are added to those data labels that will exceeds some offset threshold after reposition.

On Labels tab, user can set Data Labels to be attached to a Horizontal Line (Y line), Vertical Line (X line) instead of default attachment to data point and auto reposition in the other direction to avoid overlapping. Leader Line can be set to Polyline type.

The following are the Attachment settings and Auto Reposition Settings to achieve the graph above.

  • Attach: Y Line – So the Y position of the data label will be aligned to horizontal Y line. Y1 means bottom X, Y2 means Top Y, user can also use other Labtalk variables.
  • Y Offset to -500.
  • Position Below.
  • Rotate: 270 so text read from top to bottom.
  • Auto Reposition to Avoid Overlapping: X.
  • Leader Line Connect: Polyline Vert.

User can click again to select a special label or Ctrl+click to select a single label text. User can drag it to new position. Or double click the special label to customize it. An individual node 7(row index) will be created on the left panel for special point.
