  2. Use the TAB key to toggle between the following standard annotation options which you can see on the top-right corner of Annotation tool icon:
    1. In a 2D XY data plot:
      • (X coordinate value, Y coordinate value) Creating Annotation XY.png
      • (X coordinate value, Y coordinate value) [index number] Creating Annotation XYi.png
      • X coordinate value Creating Annotation X.png
      • Y coordinate value Creating Annotation Y.png
      • Index number (row number) Creating Annotation i.png
    2. In a contour:
      • (X coordinate value, Y coordinate value, Z coordinate value) Creating Annotation XYZ.png
      • (X coordinate value, Y coordinate value, Z coordinate value) [Row index number] Creating Annotation XYZi.png
      • (X coordinate value, Y coordinate value, Z coordinate value) [Row index number] [Column index number] Creating Annotation XYZij.png
      • X coordinate value Creating Annotation X.png
      • Y coordinate value Creating Annotation Y.png
      • Z coordinate value Creating Annotation Z.png
      • Index number (row number) Creating Annotation i.png
      • (Index number (row number),Index number (column number)) Creating Annotation ij.png
  3. Click to select the data point to which you want to add the annotation, and then double-click on the selected data point to add the custom annotation label when the red cross appears.

When you select a data point of a data plot, you can click on the data plot, and then press ← and → on keyboard to select the one you desired.

Editing an annotation

To quickly customize an annotation, right click on the label and select Properties… to bring up Annotation dialog:

  1. As any other text objects, you can edit and format the text of the annotation in Text tab and its frame and background in Frame tab.
  2. The leader line is a line object attaches an annotation object and points to its reference position. If you want change the style of leader line, go to Leader Line tab.
    Note: Once an annotation created, you can drag it to anywhere but in this Graph page, and the leader line connecting the label to the data point will follow.
  3. If you want to reposition the annotation to another data point, go Position tab and enter the X Value or Point Index to reposition the annotation to the specified point. Also, you can reposition the annotation to the data point has minimum Y or maximum Y by clicking Min Y button Creating Annotation MinY.png or Max Y button Creating Annotation MaxY.png directly.

    You can select an existing annotation label and press ALT key, when the cursor turns into Creating Annotation ALT.png, drag the annotation to reposition it to another data point.
