Is it possible to display a variable value within the ThingSpeak plot area?

Use a MATLAB Visualization and the text() function to add the number you want to the plot. You can add the visualization to your channel view. The built in ThingSpeak plots do not support adding a label like you asked, but there is also the numeric display widget that you can add yo you channel view.
Here is some example code ( I used MATLAB playground to help)
x = linspace(0,pi,200);
y = sin(x);
figure
plot(x,y,'b','LineWidth',1.5)
xlabel('x')
ylabel('sin(x)')
title('sin(x) from 0 to \pi')
grid on
text(pi/2, 0.5, '17', 'HorizontalAlignment', 'center', 'VerticalAlignment', 'middle', 'FontSize', 18, 'FontWeight', 'bold')

I am not brilliant with ThingSpeak but if you don’t get any other answers please let me try to help. Please give a more detailed description of what you want, perhaps sketch it down on paper so we can see your goal?
