Setting NoData to 0 causes entire raster not to render

[JamesLMilner]

Hello, firstly thanks for a great little library much appreciated. At the moment I am trying to render a GeoTIFF on an OpenLayers 3 map with Plotty. Things are going great up until the point where I try and set the no data value (in this case to 0, represented by the dark blue in the image below). The whole layer simply disappears :(. No error messages are thrown in the console.

Hello James, nice to hear you find the library useful. I am trying to reproduce your issue but setting the nodata value (for example to 0) seems to be working as expected in a series of tests. For the webgl rendering as well as for the javascript fallback. Im not sure if it is an issue related to how the rendering is done in combination with open layers. Could you provide a code snippet on how you are using it? Or maybe even point to the file you are using? **edit: Looking at the provided image i had another idea, setting the no data value will make plotty not to render it, meaning all blue will disappear and only relatively small features (some pixels) will have color. Are you sure nothing is being rendered?

Hey, thanks for getting back to me.

You can check out my code and data here (it's quite large ~35mb):

Looking at your second point, this doesn't seem to be the case unfortunately:

With 0 set to the noDataValue:

I managed to resolve my issue, looks like the extent wasn't set correctly which must have been throwing some of the logic off somewhere in the library. My bad!

Glad to hear you find a solution!
