MathJax in the axes labels of Flot - flot

Question

I would like to render LaTeX in the axes labels of Flot. It works the first pass through on this page because this is executed in my header:
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
tex2jax: {inlineMath: [["$", "$"], ["\\(", "\\)"]]}
});
</script>
<script type="text/javascript" async src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
However, the user has the option of entering new parameters other than the defaults and executing a JS via <input type="button" value="Evaluate" onclick="discrete()">. It's at this point that MathJax fails to "see" what's happening at the end of discrete.js:
MathJax.Hub.Config({//needed?
tex2jax: {inlineMath: [["$", "$"], ["\\(", "\\)"]]}
});
function doPlot(position) {//Flot
$.plot("#placeholder", [//data
{ data: z_m_plot }
],//options
{
series: {
points: {
radius: 3,
show: true,
fill: true,
fillColor: "navy"
},
color: "navy"
},
xaxis: { axisLabel: "$z_{max}(j - 1)$" },
yaxis: { axisLabel: "$z_{max}(j)$" }
}
);
}
doPlot("left");
Is there a way to pass individual strings to MathJax in order to render $z_{max}(j - 1)$ and $z_{max}(j)$ in the axes labels?

Answer 1

MathJax runs on page load and converts the math markup. If you want it to run again after you redraw your plot add this:
doPlot("left");
MathJax.Hub.Queue(["Typeset",MathJax.Hub]); // queue up MathJax
