using,

public override string ToString()
{
return "My Chart";
}

How can I change the font parameters ?

Secondly, how would I go about changing the labels in the "Indicator" panels as well ?

I found that the custom chart label font parameters could be changed simply in the "Chart Properties" window.

Still need an answer regarding placing similar label in an indicator panel...

The indicator label, you can change that in the indicator panel, it gives a standard text that comes
from the indicator, but you can change it to anything, or put it to empty.

I generally leave the label blank for each indicator to keep the panels clean.
If I place any text in an indicator label box, it displays what I typed plus all of the parameters for the indicator.
I don't want the parameters listed, just a text label in the indicator panel.
unless I'm mis-understanding, in which case, I apologize.

No way around that other than to write your own text onto the panel, then you get to set whatever font you want as well, either through Ninja fixed text call or direct graphics draw string call.
