The Refresh method enables and disables the refresh (drawing) of the graphics window. This method is useful if you are doing a large number of graphics updates and you do not want to see the intermediate steps.

Example

---

; Run this line of code first.

p = PLOT(/TEST)

; Disable re-draws.

p.Refresh, /DISABLE

; Change some properties, add another plot.

p.COLOR = "red"

p.FILL_BACKGROUND = 1

p.FILL_COLOR = "yellow"

p.TITLE = "My Data"

p1 = PLOT(FINDGEN(21)*10, RANDOMU(seed,21)-0.5, "g2o-", /OVERPLOT)

WAIT, 1

; Re-enable drawing and show the results.

p.Refresh
