Javascript Question

I have a rowchart that currently looks like this:

`deltaChart`

.width(300)

.height(250)

.dimension(deltaDim)

.group(pointsByDelta)

.xAxis().ticks(4);

In which the

`deltaDim`

`pointsByDelta`

`deltaChart`

Since the

`deltaDim`

I've tried just simple ordering like this:

`.ordering(function(d){return -d.value})`

That results in error. Ideally I'd like to be able to do something like:

`.ordering(function(d) {`

if(d.value == "5 ft") return 0;

else if(d.value == "4 ft") return 1;

else if(d.value == "3 ft") return 2;

else if(d.value == "2 ft") return 3;

else if(d.value == "1 ft") return 4;

else if(d.value == "0 ft") return 5;

else if(d.value == "-1 ft") return 6;

else if(d.value == "-2 ft") return 7;

else if(d.value == "-3 ft") return 8;

else if(d.value == "-4 ft") return 9;

else if(d.value == "-5 ft") return 10;

else return 11;

})

It looks like most of the posts on this topic are responded to with a way to sort in ascending or descending order. I've not even been able to get that to behave, and in my case, I need to be able to dictate the order if possible.

Any help appreciated. Thank you!

Combined with Gordon's input from above regarding .xAxis(), the solution that works is as follows.

```
deltaChart
.width(300)
.height(250)
.dimension(bfeDeltaDim)
.group(pointsByBFEDelta)
.ordering(function(d) {
if(d.key == "5 ft") return 0;
else if(d.key == "4 ft") return 1;
else if(d.key == "3 ft") return 2;
else if(d.key == "2 ft") return 3;
else if(d.key == "1 ft") return 4;
else if(d.key == "0 ft") return 5;
else if(d.key == "-1 ft") return 6;
else if(d.key == "-2 ft") return 7;
else if(d.key == "-3 ft") return 8;
else if(d.key == "-4 ft") return 9;
else if(d.key == "-5 ft") return 10;
else return 11;
})
.xAxis().ticks(4);
```
