Hi I am pretty new to PyQtGraph so help is much appreciated.
I am currently making a polarplot with pyqtgraph. I have a histogram and a colormap. The area outside the circle I am plotting has NaN-values in the data matrix containing the plot values, like this: NaN NaN NaN val NaN NaN NaN NaN NaN val val val NaN NaN NaN val val val val val NaN val val val val val val val NaN val val val val val NaN NaN NaN val val val NaN NaN NaN NaN NaN val NaN NaN NaN Currently I do this, using scipy's griddata function and these variables: x, y : points data : values I want to plot in the circle Xi, Yi : grid fill_value : Value used to fill in for requested points outside of the convex hull of the input points self.interpolated_data = griddata( (x, y), data.astype(np.float), (Xi[None:], Yi[:, None]), method='linear', fill_value=limits[0]-100) where 'fill_value' sets NaN values to 100 below the bottom limit. However, this makes this area blue with 'jet' colormap (yes I know everyone hates jet). I want to skip plotting these points altogether, how could this be done? -- You received this message because you are subscribed to the Google Groups "pyqtgraph" group.
