symbol for "delta" #147

Closed pixelzoom closed 5 years ago

pixelzoom commented 5 years ago

Noticed while reviewing English strings for code review #143.

In curve-fitting-strings_en.json:

  "deltaEqualsPattern": {
    "value": "D<sub>y</sub> = {{deltaValue}}"
  },

This appears on the points, like this:

Is "D" the proper symbol to be using for "delta"? Why not "Δ" or "δ" ?

The original uses 'D' so I just assumed that's what Mike wanted, but I just emailed an confirmed with him that it should use the capital greek delta. Please use '∆' instead of 'D'.

Changed in the above commit, see screenshot below. In #159, we're still working out whether this should be using math font.
