====Max (Analytic Filter)====

===Description===
The **Max** filter is used to calculate the maximum value from the data set.

When used on //multiple// rows, it returns the per-row maximum (ie. it will return the same number of columns and only one row).

When used on a //single// row, it returns the overall maximum (ie. it will return a single number).

This is the same as using the Pandas 'max' function on a DataFrame.

===Parameters===
This filter has no parameters.

===Example===
<code>
<filter type="Max"/>
</code>

//Calculates the max of the data frame//
