subscript in ylabels of heatmap

1 次查看(过去 30 天)
Hi
I want to write a word with subscription in ylabel of the heatmap.
but is shows: A_b
how can I edit this?
how can I show the xlable values as yearly (1971,1972,...)?
tbl = readtable('heatmap.test.xlsx');
t1 = datetime(1971,1,1);t2 = datetime(1986,12,1);
t = t1:calmonths(1):t2;t= t(:);
xlabels = string(datestr(t,12));
ylabels = {'A_b' 'B_b' 'C_b' 'D_b'};
cdata = tbl{:,2:5};
h = heatmap(xlabels,ylabels,cdata');
idx = [true;diff(year(t))] ~=0; % index of datetime values to show as x tick
h.XDisplayLabels(~idx) = {''};

Starting in R2019a, heatmaps interpret text using TeX markup instead of displaying the literal characters. Therefore it seems you are using a release earlier than R2019a. Therefore, upgrading to the latest release might help!
For displaying "xlable values as yearly (1971,1972,...)" use the code below
close all; clc;
tbl = readtable('heatmapTest.xlsx');
t1 = datetime(1971,1,1);t2 = datetime(1986,12,1);
t = t1:calmonths(1):t2;t= t(:);
xlabels = string(datestr(t,10));
xlabels = char(xlabels);
xlabels = cellstr(xlabels);
ylabels = {'A_b' 'B_b' 'C_b' 'D_b'};
cdata = tbl{:,2:5};
h = heatmap(cdata');
h.XDisplayLabels = xlabels;
h.YDisplayLabels = ylabels;
idx = [true;diff(year(t))] ~=0;
h.XDisplayLabels(~idx) = {''};

Thank you so much.
the code works well.
do you think the subscription in R2018b does not work for the heatmap?

You need to upgrade to at least R2019a to avail the tex markup feature in the function heatmap. tex markup for heatmap was not supported until R2019a.
