Show the numbers in one color in scatterplot
显示 更早的评论
Hi,
Please look at the following code. I need to show the points (as numbers) in black color. But it is showing in different colors according to the colormap. How can I make it show all the points (as numbers) in black color (just one color).
Thanks in advance.
n = 6; % number of data points
cmap = jet(n); % builtin colormap; could choose another...
C = mat2cell(cmap, ones(1, size(cmap, 1)), 3); % reshape for 'set'
k = [1:n].';
marker_size = 25;
marker_type = 's'
xlim([2 6]),ylim([2 6])
ht = text(Ob_All_avg, WGEN_All_avg, num2str(k));
set(ht, {'Color'}, C)
set(ht, 'FontWeight', 'bold','FontSize',18,'edgecolor','none');
colormap(cmap);
box on
line([2,6],[2,6],...
'linewidth',0.6,...
'color',[1,0,0],'LineStyle','--');
set(gca,...
'xlim',[2,6],...
'ylim',[2,6]);
axis square;
xlabel('TRMM (1998-2012)','FontSize',14)
ylabel('WGEN generated 10000 yrs','FontSize',14)
title('Daily Mean','FontSize',14)

Damith - where is the line (or lines?) of code that is used to plot the data via scatter? Unless you mean the line of code
ht = text(Ob_All_avg, WGEN_All_avg, num2str(k));
which displays the numbers from 1 through 6 at coordinates defined by Ob_All_avg and WGEN_All_avg which does plot the numbers using the colormap defined by jet(n).
If you want these numbers just in black then just remove the lines
cmap = jet(n); % builtin colormap; could choose another...
C = mat2cell(cmap, ones(1, size(cmap, 1)), 3); % reshape for 'set'
and later
set(ht, {'Color'}, C)
which sets the colour of the text (numbers) to that of the colour map. With these three lines gone, the default colour of black should be used.
