Here, the colorbar is narrowed and the axes position is reset so that there is no overlap with the colorbar. contourf (X,Y,Z) specifies the x and y coordinates for the values. 6% of the data is <10 or NaN. Change Colormap. How can I ensure that the data is always plotted using the same scale even if the range of z is. 0, 3. I would like to set the same colour scale for each subplot so that a single colorbar can be used for all of them. If you drop the "LineStyle","none" you get contour lines even in the pure yellow area and in the pure dark blue area. set these inversly scaled colorbar ticks: set(a3,'YTickLabel',ticks) and you finally get a seemingly linearized plot (but you could just backup your non-linear data from before), with a with non-linear colormap and colorbar ticks. fig,ax = plt. This does not affect where the actual contour lines go, though. The smallest value in your data maps to the first row in the colormap, and the largest value maps to the last row in the colormap. 1 Answer. The colorbar does display some log-scale ticks but the labels displayed do not correspond at all to the value being plotted. If the current axes contains a contour object created by the contourm, contourfm , contour3m, or geoshow function, then the number of colors in the colormap matches the number of contour intervals. It also determines the orientation of the colorbar (colorbars on the left and . The 16 contour lines have been drawn for that. Oct 29, 2009. x = [-1:0.
