make unshaded line graphs

[tom]

After looking through the documentation, I do not think this is
possible, but I want to make sure.

Is it possible to make a line graph with the area under the line
unshaded?

Thanks

I did some customization of my own a while back to make this possible. I dont have a lot of time to explain it right now but you can take a look at this site

http://igs.indiana.edu/mes


If you look at the source of the first page you will see that there is a new type of chart called "lineonly"


The javascript files that are modified I believe are http://igs.indiana.edu/mes/javascript/plotkit/layout.js and http://igs.indiana.edu/mes/javascript/plotkit/canvas.js. I believe that I have commented places where I have made changes.
I am not sure if I modified Base.js or not. I did document this a long time back and I believe I had send it in as an enhancement but it was never incorporated, I know that this project is sort of on the backburner now for the principles.

Feel free to rip the code and use it, I have not updated the plotkit library since I modified it so it may not be uptodate, I worked on this project a while back.


Hope this helps
Cheers
Prem

Check out the plotkit-patches version of PlotKit. It supports
plain-line graphs for Canvas. I had to patch the drawing a bit to make
it look nice.

Or you could always try the same { shouldFill: false } option with
standard PlotKit.

I think I have figured it out. Its really simple actually. Apperently
there is a "shouldFill" option in the Renderer contructor.

I just set that to false and had a normal line graph. Thanks for the
help guys.

Oops, I just saw that Per made the shouldFill suggestion already.
Should have checked here sooner :(

Ehm... I think that is what I said:

But I still recommend you to give the PlotKit patches code a try. It
looks much nicer in this case if you are using Canvas.
