Control Colormap Limits. For many types of visualizations you create, MATLAB ® maps the full range of your data to the colormap by default. 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. All intermediate values map linearly to the intermediate rows of the colormap.Nov 11, 2015 · You are on the right lines setting ytick, but as you noticed this only changes the position of the ticks on your colorbar, but the scaling stays the same. Instead, try to set yticklabel: % Show the colorbar. c = colorbar; % Define the desired ticks. ticks = [0:10:180]; % Sets the correct location and number of ticks. The reason for this is the way pixel values are mapped to colormap colors, which can be seen by showing a colorbar. Your custom colormap happened to work because red was used for pixels with a value of about 0.5 - of which there were none. What you need to do is correctly set the color limits for your axes:The first color in the colormap will correspond to a min value that I set manually, and the last color to the max value. I also want to draw a colorbar beside the axis I draw the data.

c = colorbar; The default location of the colorbar is on the right side of the axes. However, you can move the colorbar to a different location by setting the Location property. In this case, the ' southoutside' option places the colorbar below the axes. c.Location = 'southoutside'; You can also change the thickness of the colorbar.Hi : I wanted to write a small code to generate a colorbar with limits from -180 to 180. any help please? 0 Comments Show -2 older comments Hide -2 older comments ….

The contourf function uses the current colormap to fill the spaces between the levels in the plot. The first color fills the space between the lowest level and the level above it. The last color corresponds to Z-values that are greater than the highest level in the plot.If Z contains values that are smaller than the lowest level displayed in the plot, the region …You can set the locations of your ticks like so: set(h, 'XTick', [Min, (Min+Max)/2, Max]) Be aware that this will probably not look correct, unless the colour limits of your plot are set to the range [0.8, 12]. You can do this with: set(gca, 'CLim', [Min, Max]) Furthermore, a better way of adding the units 'mm' to your colourbar would be as ...
