I have to make a netgraph with 5 axis which meet at one end. With MS Excel it is easy but you can not scale them seperately.

Who knows a way to do this?

Thanx for help!

Origin does not have a "Radar Plot" or any of its variants, but since we do support multiple axes, you can get something similar using our Polar Plot.

The graph below is a four layer plot with four polar graphs that have been merged to a single graph with three layers linked to one. Note the custom offset of the Y axis and their color-coding to their data. Each Y axis has its own scale. We can't do tilted axes, so this seems the best way to display using Origin.

These Y datasets use 0-90-180-270 as their X values and another dataset of text (First-Second-Third-Fourth) is used for the X Axis Tick Labels.

I just tried following this advice, but can't get it to work. Your example seems to be scaled for each Y dataset, not each of the axes.

A concrete example of cereal flakes may help:
First axis: moisture content (10-16%)
Second axis: water absorption (50-120%)
Third axis: flake thickness (0.5-1.2 mm)
Fourth axis: bulk density (300-500 g/l)

We have various uses for the flakes (breakfast cereal, biscuits, porridge). We want to compare profiles of various products with the needs of the end-user.

The only thing that I found that worked was to normalise the data, but this does not make the results easy to interpret. Any more suggestions? For example, a better way than radar plots.

Thanks
