How can I get the frame of one of the x-axis labels in the horizontal bar chart of Charts?

I've created a bar chart by using the Charts framework. Currently, I'm trying to draw a red circle underneath the current day. However I'm not able to get a reference to the bounds nor the frame of the x-axis labels. How could I achieve this?
What I want to achieve is something like the added image

Restrict the dragging/movement of smart lines in fusioncharts to avoid weird shapes

I'm creating doughnut chart with smart lines and labels. When there is only one item in the chart, I'm facing an issue. If you drag the smart label or line around, the chart changes its shape in some angles. When the doughnut chart has 3-4 items this doesn't occur. I have attached screenshots. Is there any way to fix this or disable the rotation of chart when lines/labels are dragged?
To restrict the dragging of smartlines, add "enableRotation": "0" to the chart object. Here's the updated fiddle http://jsfiddle.net/g1254w67/19/

geoJson stroke overlap on hover

I am creating a MapBox project with a geoJson vector layer. I have been using the following example as my guide.
https://www.mapbox.com/blog/neighborhood-mapping-with-dynamic-vector-data-layers/
When I hover over any geoJson feature the stroke is changed to 2 pixels. However the stroke gets clipped by the neighboring features sometimes. I believe this has something to do with how the different features are stacked. So if I hover on a feature which is stacked near the bottom the neighboring features are covering that stroke.
Here is an example...

Is their a way to set the stroke to be inside of the polygon or a way to bring a feature to the top of the stack when hovering?
Thanks for any help!
By adding the function
layer.bringtoFront();
after setting the hover styling your polygons will come to front.

Dojox charting legend image rotation

Is there a way to rotate an image symbol in the legend widget??
I'm using a few vertical lines in my graph to show the location
of a leak on a chart. The legend shows these lines as horizontal
which is fine but, it would be better to rotate it and show
a vertical line. That would be wayyyy more intuitive to the user.
Thx!!
