    Mike,

    ·· You can use the Parallax 2X16 Serial LCD Display for this purpose.· Not only can it show both temps on one line, but if you need a Bar Graph, there is an example in the Projects Forum.

    If it is just a simple bar graph you can get away with a character display using block graphics. However,
    have a look at parallax lcd section, they have some with pixel graphics capabiliites:

    an other source (also docu & specs available):

    You mentioned a Bar Graph in your first post, and a Line Graph this time.· Bar graphs can easily be done on character LCD Displays...Line Graphs require a graphical display.

    Line Graphs require a graphical display.

    Buy a used nokia 5160/5165 cell phone(make sure it works) and do this:

    Hi Mike,

    You may also want to check out Matrix Orbital serial interface displays aswell. We have included bar graph commands built into the modules. All you would need to place in your code is the command syntax which is outlined in the manuals. Everything is adjustable in the software, and it's easily interfacable with the Basic Stamp. There are plenty of examples with the Basic Stamp communicating with a Matrix Orbital display shown at www.matrixorbital.ca/appnotes/basic_stamp/ I would take a look at one of the displays manual like the LK162-12. This is a 16x2 character display, and the manual is located at www.matrixorbital.ca/manuals/LK_series/LK162-12/ You check out our large selection of dislays at www.matrixorbital.com/

    Feel free to PM me, if you have any further questions.

    Yep, you'll need a graphical display, and some practice programming one.· This won't be something that there will be a packaged code to do.· And the code will vary with the display.

    Mike,

    ·· As I said, different LCD Displays have different ways to program them.· You will have to decide on one first, then worry about programming it.· Depending on the display you choose, there may or may not be programming examples out there that you can use.

    Also bear in mind...You show a plot of temperature over time, so you will need to find a range of that plot and contiously update the display with it, but only after you've filled both panes with that data.· There are some displays which are graphical and which support multiple user zones, but it really depends on your programming skills as to how easy/hard it will be.

    This site was recently posted in another thread on color LCDs, it might be worth looking at.

    I'm a big fan of Scott Edwards' displays.· It's been a while since I've done anything graphical, but this article might help.
