Charts Graphs and CCK with user input

So I'm still way new to drupal, but I'm trying to put something together where I can have users input data, then have that data show up on a chart.

For example: I have made an input page that has 4 CCK fields. One of the fields is a date, and the other three are numbers from various projects.

I want the user to put in the date, plus the numbers -- then have the X-axis on a chart be the date (so the x-axis would grow each time someone put something in) and then have the chart all three numbers on the y-axis. If I had to only do one number at a time, I could, but it would be convenient to have all three plotted on the same graph. It would be even nicer if I could have one them a bar graph, and the other two lines. But thats not as important.

I've been able to do something kind of like this with Views and Views-chart. Its okay, and I may be able to figure it out to work well enough. Like I said I'm pretty new with drupal and views is a monster in how much it can do. But I'm slowly figuring it out.

But I've also installed fusion-charts (and fusion-charts-cck), and it comes with some demos that are pretty cool. But I can't figure out how to make it do something like views-charts where I can choose which value to be the x-axis and how many fields to include in the y-axis. I'm really hoping there is a way to do this with minimal php coding, because I have very little skills there.

Thanks everyone for the help. I really need it, and I appreciate a ton.
