Radar Chart - need a suggestion

[rickai]

Hello everyone, I have a created multiple radar charts to monitor 7 indicators. The 7 indicators are all rated on a % scale 0-100%. To improve resolution for items above 90% (couldn't tell the difference between 98% and 100%), I changed the scale to start at 80 and go to 100%. However, now items below 80, or even the rare occasion I get a zero, the chart looks really funny. So, my question is, how do I get good resolution on the above 90%s while not looking ridiculous on the zeros? Thank you!

You might reconsider the choice of chart type.

Without knowing your data and not knowing what you want to show with your charts, I can't, with any confidence, suggest alternatives.

Probably not what you’re looking for but I thought I’d throw it out there anyways. Does creating two charts per indicator work? One at 0-79% and one 80-100%.

As ThisOldMan hinted, radar charts suck. A better way to plot similar data is using parallel coordinates. See Wikipedia or Eager Eyes for good descriptions.

Hi everyone. Thank you for the tips. I don't disagree with the radar chart comment - however, that is what I'm stuck with based on management decision. That said, is there a way to have the focus of the scale be in the upper 20%, but accommodate lower values with out looking ridiculous? Thanks again.

Sorry, Rickai. I understand having to deal with management edicts, but I don't know how to make radar charts not look ridiculous.
