Profile tool : wrong display for large z number

[sebbelese]

Hi,

I am using the profile control tool to display different types of data along lines.

However, for large values, the display is wrong with hidden digits, some of which are also placed under the vertical label.

I think that this behaviour could be easily improved by switching to floating point notation when the numbers are too large, i.e. modifying line 705:

             if (this.get('zunit') != 'km') ctx.fillText(i.toFixed(fix), -4*ratio, i*scy+dy);

Maybe linked with #738

Profile control is mainly designed to display altitude (at least 4 digits) and there is no origine offset.
Using zunit = 'km' lets you divide values Z value by 1000 (kilo units) for more visibility (floating point), use zDigits to set the number of digit you want (default is 0).
Graduations are rounded for display, you have to set the graduation option to fit a round coordinate on the Z axis.

I think you can try setting:
zunit: 'km',
graduation: 1000,
zDigits: 1

Thanks for your reply.

I understand that the tool mainly targets altitude but it is very general, certainly enough to be used for any kind of profile, except maybe due to the formatting of these labels.

If you are interested to improve this, I proposed some changes in a post request that I just created (#749).
