How do I make a chart with multiple material parameters on y-axis?

      Hi,

      I am trying to plot the following two parameters for all metals, plastics, and composites in the Granta EduPack database:

      1) Energy required to melt [kJ/kg] = 8.4*Cp*Tm, where Cp and Tm are specific heat and melting temperature;

      2) Energy required to deform [kJ/kg] = 3*(sigma_y + sigma_uts)/density, where sigma_y and sigma_uts are yield and failure strengths

      Currently I am able to make 1D charts of these parameters for each material class. Below I show the two plots for all plastics in the database.

      At the top left hand corner of the chart creating dialogue box, you'll find tabs for the X and Y axis. Click on each of these to select the parameter for that axis. When you've done them both, you can click OK and you'll have a bubble chart.

      So that works for making a bubble chart. But I'm hoping to make a 1D chart with nothing on the x-axis and the both parameters plotted on the y-axis. Something like this:
      So I want Granta EduPack to output a plot with both the melting and deforming energies on the y-axis for each material class: plastics, metals, and composites. Then I can make this chart by stitching together the three individual plots.
      Is this possible with the software? Is there any way to output the numerical values in the database?

      Hello, there,
      There is a trick I have used a couple of times for your reference:
      Create both charts in edupack with the scales adjusted
      Copy both into PowerPoint, set the background to transparent
      Overlapping two charts together
      I have create a quick example (without aligning scales though, just to show the idea):
      Hope this could be of some help.

      This is a much better figure

      Thank you WZhao, I will try this.
      How did you create the individual plots with composites, metals and alloys, and plastics all plotted on the x-axis?
      When I plot the parameter with a custom subset of composites, metals/alloys, or plastics, I only get one material class on the x-axis.
      And to match the scales, I should set the same max and min limits for both plots, right?

      Hi You are right about the scales. This is what I have done so far.
      As to add different material class on x-axis, I used the Advanced under Chart:
      (BTW, the axis setting down there is where I set the scales)
      And then if you go to Trees:

      You are then ready to add whatever material class you would like to. I am guessing until now you should be able to create the individual charts as the way you like them.

      Hi, to get such graphic it is explained above by defining material families you want to show in the tree option of x-axis. And for the y axis limits (min and max, it depends if you show 1 or 2 axis on your graphic. If you keep 1 axis, you have to set the same max and min values for the y-axis. If not it doesn't matter but you have to play on the color for example to differentiate the 2 different plots (eg Young's modulus and Yield strength).
