Use .charAt(0) === 'x'/'y' to test for xref/yref pointing to an axis.

Thanks @my-tien for the fix.
Two questions:

  1. Is a similar fix needed for the case of path?
  2. Could you please add a test here:

    plotly.js/test/jasmine/tests/draw_newshape_test.js

    Line 1433 in 79559af

    describe('Activate and edit editable shapes', function() {
    ?

I'll have a look at path and adding a test. However, my fix is not yet correct. Among other things, afterEdit can be a shape with xref and yref paper apparently even if the ref was something different before. I'll have to see, how I can correctly translate the shift variables to paper as well. I will probably push some changes later today.

UPDATE: This is a separate bug. As mentioned further below, I'll open an issue for it later.

For the path case the change is not necessary, because the shift properties are ignored if path is used instead of x0, x1, y0, y1.

Regarding the test, I added one with a test case that previously failed and now works. However, I am not sure how to test this locally because for some reason on my machine several Jasmine tests always fail. Could you please look at it on your end and make the necessary adjustments?

If you change it( to fit( then you could only run this test on your machine using

npm run test-jasmine draw_newshape

Plotly.newPlot(gd, {
data: [
{
x: ["2015-02-01", "2015-02-02", "2015-02-03"],

FYI - The test didn't pass on my machine.

Instead of path shouldn't we look into x & y parameter changes?
