Deneb Vega-lite: AND/OR logic

Question

Hello everyone,I have a control chart (see below) which I want to set a conditional color "red" if the Diameter is above or below required limits, "Diameter LSL" or "Diameter USL". If within limits "darkblue"-I struggle to find the correct syntax in Deneb to add AND/OR statements to the condition test.if ((Diameter &gt; Diameter USL) OR (Diameter &lt; Diameter LSL))...How can I modify the code below (or is it an better way to achieve the results I want?) to also set the mark below Diameter LSL to "red"? },
          "encoding": {
            "color": {
	            "condition": {
	              "test":  "datum['Diameter'] &gt; datum['Diameter USL']", "value": "red"
                     },
	              "value": "darkblue"
	    },

Hi&nbsp;Salle,
You can use JavaScript logical operators in expressions, so something like the following will work:
"test":  "datum['Diameter'] &gt; datum['Diameter USL'] || datum['Diameter'] &lt; datum['Diameter LSL']"

And: &amp;&amp;
Or: ||
Not equal: !=

If you're using the predicate approach (using more structured objects rather than expressions), you can use 'predicate composition' to combine these using arrays - there's an example at the bottom of the doc page here.
Hopefully this will help get you moving. Good luck!

Daniel
