 Q:

multidimensional mutable Vectors: possible? if so, how?

i notice that the generate function is not defined for mutable vectors. i'm wondering if there is another way to define multidimensional mutable Vectors in haskell

A:

I assume your mean something from the vector package, like Data.Vector.Mutable? 
It provides several ways to create and fill mutable arrays, such as with replicate. However, the vector package is for 1-dimensional, growable vectors, not multi-dimensional arrays.
For n>1 dimensions, you need to either code the index manually, or use repa or hmatrix.
repa, in particular, is interesting, as it also provides automagically parallel operations, and you can fill one from a vector. However, repa arrays are immutable, and rely on fusion for a nice interface.
If you need mutable and multi-dimensional arrays, you might have to resort to the old school array package, and one of the MArray types.

 Q:

dynamically update the scale type of chartjs graph

I have a bar chart on a page that has data displayed that is dynamically updated.  The problem I have is that I need to change the type of the y-axis based on the data that is displayed.  I need it to be a linear scale when the data has a range of less than 100 (e.g. 0-99) and logarithmic if it is greater (e.g. 0-1000).
I can calculate whether I need a logarithmic scale or not fine, but when it comes to changing the scale type I am at a loss.  I have tried changing the options object of the chart and calling update():
myChart.options/scales.yAxes.map(function (axis) { axis.type = 'logarithmic' });
myChart.update();

and also tried changing the scale itself directly:
Object.keys(mychart.scales).forEach((function (axisName) {
            var axis = myChart.scales[axisName];
            if (axis && axis.id.startsWith('y')) {
                axis.options.type = 'logarithmic'
            }
        }));
myChart.update();
