How to plot 2 series of values to the same y axes?

[eox2]

Basically I have 2 sets of data (both measuring different things) but I want to plot them on the same graph using the same axes. I figured out how to plot it with 2 different axes but then they both are very close and I don't want that. I want the contrast to be visible between the range of values since one set of values is way lower than the other.

var svg = dimple.newSvg("#chartContainer", 590, 400); var myChart = new dimple.chart(svg, thetable); var x = myChart.addCategoryAxis("x", "entries");

x.showGridlines = true; x.addOrderRule("entries");

var y = myChart.addMeasureAxis("y", "tpp");

var s = myChart.addSeries(["entry","tpp"], dimple.plot.line); var s2 = myChart.addSeries(["entry","ap"], dimple.plot.line);

myChart.draw();

I am not too familiar with the API. I want the y axis to be universal and plot both series relative to the same y axes. However, I am having trouble doing that as I don't know the api very well and the things I did try are not working. The only way it somewhat works if i create a seperate y axes and plot it against that but then I don't want that.

Thanks for your help.

Don't you just plot the second series using the same scale as the first?

Well no because then it has no way to distinguish and it would be the same results. The y values are what determine its location on the y axes.

If I understand your situation correctly I think you just need to create a composite axis but your code only has a single data set and no measure axis so I'm a little confused. If I'm right then tpp and ap are both measures in the same data and you want a line for each. In which case you would do a composite axis by creating a second y axis referencing the first axis in it's first parameter:

var svg = dimple.newSvg("#chartContainer", 590, 400);
var myChart = new dimple.chart(svg, thetable);
var x = myChart.addCategoryAxis("x", "entries");

x.showGridlines = true;
x.addOrderRule("entries");

var y_tpp = myChart.addMeasureAxis("y", "tpp");
var y_ap = myChart.addMeasureAxis(y_tpp, "ap");

var s = myChart.addSeries("entry", dimple.plot.line, [x, y_tpp]);
var s2 = myChart.addSeries("entry", dimple.plot.line, [x, y_ap]);

myChart.draw();

Thank you John. That is exactly what I needed. I got it working now!
