Overlays a series onto another in a specified Window.
OVERLAY(series, win, color, sync, scales)
series |
- |
A series, the series to overlay. |
win |
- |
Optional. Window in which series is to be overlayed. Defaults to the current Window. |
color |
- |
Optional, An integer, the color value of the overlayed series. |
sync |
- |
Optional. An integer, the sync axes mode. Defaults to 0 (no sync): |

Optional. An integer, the type of scales for the overlay. |
W1: gnorm(1000,1)
W2: integ(w1);overlay(W1)
W1 contains 1000 random samples.
W2 integrates the data in W1 and overlays W1 onto the series in Window 2. The two series can be scrolled and scaled independently, preserving their own frames of reference.
W1: gnorm(1000,1)
W2: integ(w1);overlay(W1, seriesgreen, 3, 9)
Similar to above, except the overlay color is SERIESGREEN, scrolling and scaling of the traces are synchronized and the overlay uses the Y-Left scale.
Each overlay in a Window has its own set of scales.
See SCALES for valid values for the scales option.
In order for an overlay to be updated automatically when the Window is updated, it must be part of the Window formula.
Use UNOVERLAY to remove an overlayed series and axes.
See STRIPCHART and SETPLOTTYPE to create a stacked stripchart of multiple series.
See OVERPLOTALL to add overplots to a stripchart.
See NUMFOCUS to return the total number of overlays in a Window.
See XYALT to create an XY plot with an alternate X axis.
See OVERLAYXSYNC to synchronize one or more overlays based on the X axis.
