Can't plot a raster from map canvas or whole raster
Issue #4
resolved
When I try to plot using the map canvas nothing appears. When I try Whole Raster, this error happens
An error has occurred while executing Python code:

My map canvas looks like this. I have a regular raster I loaded from a geotiff, not sure what is happening when it says there is not an instance of a QgsRasterLayer. Any tips appreciated and thanks for making this tool, looks cool!

For the scatter plot you have to select two raster bands inside the Raster Data Plotting Dock Widget (i.e. X Axis and Y Axis).
