I am trying to plot previously collected ELISA data on a line graph and cannot seem to figure out how to plot multiple y values per single x value. For example, for each x value, there would be 12 y curves. I tried a cart extension and using the canvas block. Can anyone help?

To get help:

1.) You might explain what ELISA is. Here, done it for you

2.) Show us what you tried. Provide a data sample.

3.) An obvious method is to plot multiple y values is to plot the y value points that share a common x value in a different color. What you do depends on what your data set shows.

4.) This could be done using a Canvas or using an extension. What you do depends on what you will do with the data. If you use a Canvas, your curve drawing is limited to connect the dots. Some javascript techniques might allow curve fits. See Juan-Antonio’s javascript tricks Proposals of math codes. Area polygon. Vertices rectangle. Linear regression. Decimal IP

Here an example of Cubic Regression with JavaScript.

You put values and get the parameters of the expression.

Another possibility is to use Google chart:
