Displaying on the same chart lines and points with not the same x values

[soso77]

Hi,
I've started using Chart js recently. I'm trying to achieve something that I assume should not be too difficult, but I could not find how to do it:
I want to display abacus (eg temperature v/s pressure) and at the same time points. So far, I managed to draw on the same chart lines with my abacus and some points.
The problem is that my abacus are built based on predefined x and y label, while my points are more likely to be a fraction of the x values. E.g. if my x values are 1, 2, 3, 4... for my abacus, my points x coordinate might be like 1.32, 8.52, ...
I guess the way to tackle it, would be to have two sets of independant x-labels, but I couldn't find how to do it.
Any idea would much appreciated. Cheers.

Use linear scale.

Thanks for your answer. Doing so, ie setting type: 'linear', in xAxes displays the points nicely but my abacus (which are lines) are just not displayed. I googled it and found the following:
#4687

Someone answered:

linear x axes only work with scatter data. An example of this is http://www.chartjs.org/samples/latest/charts/scatter/basic.html

If you want to use data.labels you need to use a category x axis

But I did not understand how to use category in this case.

So you can't provide the abacus data in {x, y} format? Are your labels numbers or strings? Can you create a pen (minimal)?

An abacus I started playing with was for instance:

  data: {
    labels: ['', '1M', '2M', '3M', '4M', '5M', '6M', '7M', '8M', '9M', '10M', '11M', '12M', '13M', '14M', '15M', '16M', '17M', '18M', '19M', '20M', '21M', '22M', '23M', '24M'],
    //labels: [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24],  // or alternatively if easier, but would be interested in knowing if text labels can be mixed with integer labels
    datasets: [{
      label: "Mean",
      backgroundColor: "rgba(78, 115, 223, 0.05)",
      borderColor: "rgba(78, 115, 223, 1)",
      pointRadius: 0,
      data: [49.8842, 54.7244, 58.4249, 61.4292, 63.886 , 65.9026, 67.6236, 69.1645, 70.5994, 71.9687, 73.2812, 74.5388, 75.7488, 76.9186, 78.0497, 79.1458, 80.2113, 81.2487, 82.2587, 83.2418, 84.1996, 85.1348, 86.0477, 86.941 , 87.8161], //[0, 10000, 5000, 15000, 10000, 20000, 15000, 25000, 20000, 30000, 25000, 40000],
    },]}
