View source for Toggling Key Item Visibility

[[Category:Graphs]]

You can click on each item in Graph Key to show or hide the corresponding line or bar.

== Turn on all, Turn off all ==

Right-click on a graph Key to see menu options '''Turn on all key items''' and '''Turn off all key items'''. Use these when you want to show or hide almost all of them. They save you many clicks when there are a lot of key items.

== Show lines and symbols  ==

You can now show a graph with some data as symbols only, some as lines without symbols, and some lines and symbols.  This is very useful when you want to show data points and a line fitted to those points on the same graph.

To achieve this, select the Line+Symbol plot style:

Initially, every data series (key item) has lines and symbols (as before).  Click on each Key item to toggle it from line+symbol to line-only to symbol-only, and back to line+symbol. So with just a few clicks, you can select how to display each each series.

What if your graph has multiple keys, line and symbol or symbol size each depicting different information?  You can then toggle each element on each key separately through three states: On to Off to Partial, and back to On. In the Off state, it hides both lines and symbols. In the Partial state on the Line key, it hides the line but shows the symbols.  Or in the Symbol Key, when an item is Partial, it shows the line but not the symbol.

In the above graph, the 2 points corresponding to '''Least''' would appear at x=2 in the fully-on graph, but fit_err=Least is been clicked once, putting it into the off state. As a result, there is a gap in the lines at x=2. In the symbol size key (x cat), the x_cat=8 item is in the partial state. The points corresponding to x_cat=8 appear at x=8. In this case the lines pass through the points, but the symbols are hidden. 

When fit_graph=y in the line key is off, all the red "ink" on the graph disappears. But when it is in the partial state, the line disappears but the symbols continue to show, as illustrated here:

== Save visibility states ==
Changes to key item visibility reset by default when you close and re-open a graph anew. If you want your current visibility state to be saved as the starting point next time the graph is opened, select '''Save key item visibilities''' from the right-mouse menu.
